A new feature in iOS 5 is the support for Bluetooth 4.0 Low Energy (LE) devices using the Core Bluetooth Framework. For those who do not have a Bluetooth LE capable device, it is still possible to begin development and test Core Bluetooth iOS applications using the iOS simulator with a Bluetooth LE USB adapter. This Technical Note describes how to configure an OS X system to enable iOS simulator support for Core Bluetooth iOS applications. This Technical Note also explains the need for a Bluetooth LE adapter for OS X systems, which have Bluetooth LE built-in, for simulator testing.

This Technical Note also provides important information if you are using an OS X system for testing both iOS and OS X Core Bluetooth applications. When you make the changes described in this Technical Note, you may need to restore the system in order to run OS X Bluetooth LE application tests.

Introduction

iOS 5.0 provides the Core Bluetooth framework for creating iOS applications, which can detect, connect, and communicate with Bluetooth 4.0 Low Energy (LE) devices. The standard method for testing Core Bluetooth applications is on a device such as the iPhone 4S, which has Bluetooth LE support. In order to facilitate the development of Core Bluetooth iOS applications when one does not have a Bluetooth LE iOS device, the iOS 5 SDK simulator can be used to test these applications with the help of a third-party Bluetooth LE USB adapter. This Technical Note describes the process to enable and verify simulator support on an OS X system.

Note: Developer Technical Support does not support the iOS Simulators in cases where code execution is found to be different when executed on iOS devices. When code is found to run differently on the simulator, please submit a bug report using the Apple Developer Bug Report web site Apple Developer Bug Report web site.

Important: You must test your Core Bluetooth application on an iOS device with Bluetooth 4.0 built-in before submitting the application to App Review. Do not base your iOS application submission on the success of running the application only in the iOS simulator.

Requirements

To test iOS Core Bluetooth applications in the iOS simulator environment, you must have the following

• Mac system with Mac OS X 10.7.3 or greater

• Xcode 4.2.1 with iOS 5 SDK or greater

• Bluetooth LE USB adapter

For Mac systems with Bluetooth 4.0 built in, it is still a requirement to have a Bluetooth LE USB adapter in order to test iOS Core Bluetooth applications. An explanation as to why an adapter is required for this case is described in the section Bluetooth LE USB adapter Required on OS X Systems with Bluetooth 4.0 built-in

Steps For Enabling iOS Simulator Support

The following are the steps to enable iOS simulator support for Core Bluetooth applications.

Step 1 - Set the NVRAM Setting

Open a Terminal window and use the NVRAM command as shown in Listing 1

Listing 1 Setting the bluetoothHostControllerSwitchBehavior NVRAM Setting

A system restart is not required after performing this setting. To understand why this step is necessary, see section Understanding the OS X Bluetooth Driver Behavior

Step 2 - Attach the Bluetooth LE USB adapter

The Bluetooth LE USB adapter must be connected after performing the NVRAM setting.

Step 3 - Verify the NVRAM Setting

Open the System Information application to verify that the system Bluetooth driver is matched to the built-in Bluetooth host controller interface (HCI). For the Hardware->Bluetooth setting, verify that the Vendor ID is '0x5AC'. Refer to Figure 1 below for an example of what the System Information application window should show.

If the system Bluetooth controller is matched to the Bluetooth LE USB adapter, then the iOS simulator will not be able to use the external Bluetooth controller for Bluetooth LE services. In this case, you might see a System Information Bluetooth panel as shown in Figure 2. Here, the Bluetooth driver is matched to the Cambridge Silicon Radio (CSR) Bluetooth LE USB adapter. If this is the case, remove the Adapter and return to Step 1 - Set the NVRAM Setting

Step 4 - Enable Bluetooth in the iOS Simulator

In Xcode, launch the iOS application in the iOS 5 iPhone/iPad simulator. When the iOS simulator launches, close the application and open the Settings application and select the General tab and verify that Bluetooth is ON.

Relaunch the iOS application in the simulator. The iOS Core Bluetooth application should connect and communicate with Bluetooth LE devices, as it would when run on an iOS device with Bluetooth LE support.

Note: If there is no Bluetooth LE adapter attached to the system, it will not be possible to turn Bluetooth on in the Settings application. In running CoreBluetooth code in the simulator where there is no Bluetooth 4.0 support, -[CentralManager state] will return the CBCentralManagerStatePoweredOff result. On an iOS device with no Bluetooth LE support, -[CentralManager state] will instead return CBCentralManagerStateUnsupported.

Understanding the OS X Bluetooth Driver Behavior

The default behavior of the OS X Bluetooth driver is such that when an external Bluetooth HCI is attached, the driver will detach from the built-in Bluetooth interface and attach to the external HCI - if the HCI is not an Apple device. This behavior benefits OS X application developers who are developing Bluetooth LE applications, in the case that they have older Mac systems, which do not have built-in Bluetooth LE support. The developer can attach the Bluetooth LE USB adapter, the system Bluetooth driver attaches to the new HCI, then when the OS X Core Bluetooth application is run, Bluetooth LE services are accessed through the adapter. The downside here is that existing Bluetooth connections via the built-in driver are lost (Bluetooth HID devices for example).

For iOS Core Bluetooth application developers, this behavior is not compatible with the iOS simulator. In order to simulate the same Bluetooth behavior as the iOS device, the iOS simulator must open a direct connection with a Bluetooth LE HCI. If the built-in driver automatically attaches to the external Bluetooth LE HCI when it is attached, the simulator will not be able to open a connection with the external HCI. To control the driver matching behavior, the built-in Bluetooth driver recognizes the bluetoothHostControllerSwitchBehavior NVRAM setting. If the setting is set to 'never', when the Bluetooth LE adapter is connected, the system Bluetooth driver does not switch to supporting the external HCI.

The following is a listing of behavior settings with respect to the OS X built-in Bluetooth driver. Refer to Listing 1 for setting the bluetoothHostControllerSwitchBehavior NVRAM variable.

• bluetoothHostControllerSwitchBehavior='never' // when a new HCI is connected, the built-in driver stays attached to the built-in HCI

• bluetoothHostControllerSwitchBehavior='always' // when a new HCI is connected, the built-in driver disconnects from the built in HCI and attaches to the external HCI

• bluetoothHostControllerSwitchBehavior='default' // when a new HCI is connected, the built-in driver only disconnects from the built in HCI and attaches to the external HCI if the new module is not an Apple module.

Bluetooth LE USB adapter Required on OS X Systems with Bluetooth 4.0 built-in

On Mac systems with Bluetooth 4.0 built-in, a Bluetooth LE USB adapter is still required to support Core Bluetooth functionality in the iOS 5 simulator. As explained in Understanding the OS X Bluetooth Driver Behavior the system Bluetooth driver attaches to the built-in Bluetooth HCI. This leaves no available Bluetooth HCI for the iOS 5 simulator to attach to. For this reason, the external Bluetooth LE USB adapter is required for testing Core Bluetooth applications in the iOS 5 simulator.

Note: For Mac systems with built-in Bluetooth LE support, there is a known issue under OS X 10.7.3 in the case that an external Bluetooth LS Adapter is connected. If the built-in driver attaches to an external Bluetooth HCI leaving the built-in HCI available for the iOS simulator, the simulator fails to attach to the built-in Bluetooth HCI - Radar bug: (r. 11267888)

Testing OS X Bluetooth LE Applications

If you are testing Bluetooth LE applications for both iOS and OS X, you may need to restore the bluetoothHostControllerSwitchBehavior setting. There are 2 cases to consider.

Testing iOS / OS X Bluetooth LE Applications on a System with built-in Bluetooth LE

If your system has Bluetooth LE built-in, leave the bluetoothHostControllerSwitchBehavior='never' setting in NVRAM. With the bluetoothHostControllerSwitchBehavior setting set to 'never', the system Bluetooth driver will stay matched to the built-in Bluetooth HCI which supports Bluetooth LE and OS X application will use the built-in HCI for Bluetooth LE services.

Testing iOS / OS X Bluetooth LE Applications on a System without built-in Bluetooth LE

If your system does not have Bluetooth LE built-in, then to test an OS X application, you want the built-in Bluetooth driver to attach to the Bluetooth LE USB adapter to support the OS X application. To achieve this behavior, you must change the bluetoothHostControllerSwitchBehavior setting to the 'default' behavior. When you want the test iOS Bluetooth LE applications in the iOS simulator, you will need to set the bluetoothHostControllerSwitchBehavior to 'never'.

Simulator app, available within Xcode, presents the iPhone, iPad, or Apple Watch user interface in a window on your Mac computer. You interact with Simulator by using the keyboard and the mouse to emulate taps, device rotation, and other user actions.

The chapter presents the basics of using Simulator. You can perform these steps using your own iOS app or, if you do not have an app to use, with the HelloWorld sample code. For more detailed information on interacting with Simulator and using it to test and debug your apps, refer to the later chapters in this guide.

Access Simulator from Xcode

There are two different ways to access Simulator through Xcode. The first way is to run your app in Simulator, and the second way is to launch Simulator without running an app.

Running Your iOS App

When testing an app in Simulator, it is easiest to launch and run your app in Simulator directly from your Xcode project. To run your app in Simulator, choose an iOS simulator—for example, iPhone 6 Plus, iPad Air, or iPhone 6 + Apple Watch - 38mm—from the Xcode scheme pop-up menu, and click Run. Xcode builds your project and then launches the most recent version of your app running in Simulator on your Mac screen, as shown in Figure 1-1.

Note: If you are testing an app with a deployment target of iPad, you can test only on a simulated iPad. If you are testing an app with a deployment target of iPhone or universal, you can test on either a simulated iPhone or a simulated iPad.

Running Your watchOS App

To run your WatckKit app, choose a combination of an iOS device and watchOS device from the Xcode scheme pop-up menu. For example, to run the watch app in a 38mm watch paired with an iPhone 6, choose 'iPhone 6 + Apple Watch - 38mm' from the scheme pop-up menu.

Running the WatchKit target launches two simulators, one for the iOS device and one for the watchOS device. Figure 1-2 shows an iPhone 6 and a 42mm watch running in two different simulators.

Running Your tvOS App

To run your tvOS App, choose a tvOS device from the Xcode scheme pop-up menu. Running the tvOS target launches the most recent version of your app in a simulated new Apple TV device, as shown in Figure 1-3.

Launching Simulator Without Running an App

At times, you may want to launch Simulator without running an app. This approach is helpful if you want to test how your app launches from the Home screen of a device or if you want to test a web app in Safari on a simulated iOS device.

To launch a Simulator without running an app

1. Launch Xcode.

2. Do one of the following:

   • Choose Xcode > Open Developer Tool > Simulator.

   • Control-click the Xcode icon in the Dock, and from the shortcut menu, choose Open Developer Tool > Simulator.

To launch a watchOS Simulator without running an app

1. Launch Xcode.

2. Do one of the following:

   • Choose Xcode > Open Developer Tool > Simulator (watchOS).

   • Control-click the Xcode icon in the Dock, and from the shortcut menu, choose Open Developer Tool > Simulator (watchOS).

Simulator opens and displays the Home screen of whichever simulated device was last used.

View the Installed Apps

From the Home screen, you have access to all of the apps that are installed in the simulation environment. There are two ways to access the Home screen in Simulator from your app:

• Press Command-Shift-H.

• Choose Hardware > Home.

Use the installed apps to test your app’s interaction with them. For example, if you are testing a game, you can use Simulator to ensure that the game is using Game Center correctly.

iOS Device Home Screen

Much like the Home screen on an iOS device, the simulator’s iOS Home screen has multiple pages. After clicking the Home button (or accessing the Home screen through the Hardware menu), you arrive at the second page of the Home screen. To get to the first page, where all of the preinstalled apps are found, swipe to the first Home screen by dragging to the right on the simulator screen.

On the Home screen, you see that all of the apps that have been preloaded into Simulator. See iOS Device Home Screen.

The apps that you see on the Home screen are specific to the iOS device simulation environment. Because Passbook and the Health app are available only for the iPhone, these apps don’t appear if you are simulating a legacy device or an unsupported device type.

watchOS Device Home Screen

The Home screen for a simulated watchOS device behaves the same as it would on an actual device. You can click and drag to simulate the finger dragging around the screen and launch an app by clicking on it. Figure 1-4 shows the home screen of a 42mm watch with a developer app, the Lister sample code.

Use Safari to Test Web Apps

From the Home screen, you can access Safari within Simulator. Use Safari to test your iOS web apps directly on your Mac.

1. From the Home screen, click Safari.

2. In the address field in Safari, type the URL of your web app and press the Return key.

If your Mac is connected to the Internet, it displays the mobile version of the URL you specified. For example, type apple.com into the address field and press Return. Safari displays the Apple website. See Figure 1-6.

Use Maps to Simulate Location Awareness

Simulator provides tools to assist you in debugging your apps. One of the many features you can debug in Simulator is location awareness within your app. Set a location by choosing Debug > Location > location of choice. The menu has items to simulate a static location or following a route.

A simulated watchOS device with the location set to None checks the paired iPhone device for the location.

You can specify your own location, which can be seen in the Maps app.

1. From the Home screen, click Maps.

2. Choose Debug > Location > Custom Location.

3. In the window that appears, type the number 40.75 in the latitude field and the number -73.75 in the longitude field.

4. Click OK.

5. Click the Current Location button in the bottom-left corner of the simulated device screen.

After completing this task, notice that the blue dot representing your location is in New York, NY, near the Long Island Expressway, as shown in Figure 1-7.

Change the Simulated Device and OS Version

Simulator provides the ability to simulate many different combinations of device type and OS version. A device type is a model of iPhone, iPad, or Apple TV. Some iPhone devices can also have a paired Apple Watch. Each device-OS combination has its own simulation environment with its own settings and apps. Simulator provides simulators for common device-iOS, device-watchOS-iOS device, and device-tvOS combinations. You can also add simulators for a specific combination you want to test. However, not all device type and OS version combinations are available.

Note: To test apps for the iPad mini, use a simulated iPad with the same pixel resolution as the iPad mini.

You can switch between different device-OS combinations. Switching closes the window for the existing device and then opens a new window with the selected device. The existing device goes through a normal OS shutdown sequence, though the timeout might be longer than the one on a real device. The new device goes through a normal OS startup sequence.

To change the simulated device

1. Choose a Hardware > Device > device of choice.

   Simulator closes the active device window and opens a new window with the selected device.

If the device type and OS version combination you want to use is not in the Device submenu, create a simulator for it.

To add a simulator

1. Choose Hardware > Device > Manage Devices.

   Xcode opens the Devices window.

2. At the bottom of the left column, click the Add button (+).

3. In the dialog that appears, enter a name in the Simulator Name text field and choose the device from the Device Type pop-up menu.

4. Choose the OS version from the iOS Version pop-up menu.

   Alternatively, if the iOS version you want to use isn’t in the iOS Version pop-up menu, choose “Download more simulators” and follow the steps to download a simulator.

5. Click Create.

If the OS version you want to use is not installed, download it and follow the steps to add a simulator again.

To download a simulator

Best Jumping Cube Simulation Mac Os Download

1. In Xcode, choose Xcode > Preferences.

2. In the Preferences window, click Downloads.

3. In Components, find the legacy simulator version you want to add, and click the Install button.

You can also delete and rename simulators in the Devices window.

To delete a simulator

1. In Simulator, choose Hardware > Device > Manage Devices, or in Xcode, choose Window > Devices.

   Xcode opens the Devices window.

2. In the left column, select the simulator.

3. At the bottom of the left column, click the Action button (the gear next to the Add button).

4. Choose Delete from the Action menu.

5. In the dialog that appears, click Delete.

To rename a simulator, choose Rename from the Action menu and enter a new name.

For how to manage real devices that appear in the Devices window, read Devices Window Help.

Alter the Settings of the Simulated Device

You can alter the settings within Simulator to help test your app.

On a simulated device, use the Settings app. To open the Settings app, go to the Home screen and click or on tvOS, choose Settings. In Figure 1-8 you see the Settings app as it appears when launched in the iOS simulation environment.

The Simulator settings differ from the settings found on a hardware device. Simulator is designed for testing your apps, whereas a hardware device is designed for use. Because Simulator is designed for testing apps, its settings are naturally focused on testing, too. For example, in a simulated iOS device the Accessibility menu provides the ability to turn on the Accessibility Inspector, and the Accessibility menu on a device allows you to turn on and off different accessibility features.

Through the settings, you can test both accessibility and localization of your app. See Testing and Debugging in iOS Simulator for information on how to manipulate your settings for the various types of testing you are interested in.

Remember: Changes made in the Settings app of simulated device affect only the simulation environment that is currently running.

Rotate iOS Devices

You can use Simulator to manipulate the simulated device much as you do a physical device.

To rotate your simulated device, choose Hardware > Rotate Left. When you rotate your simulated device, Settings rotates (see Figure 1-9), just as it would on a hardware device.

Test in Simulator and on a Device

Simulator is designed to assist you in designing, rapidly prototyping, and testing your app, but it should never serve as your sole platform for testing. One reason is that not all apps are available in the simulator. For example, the Camera app is available only on hardware devices and cannot be replicated in the simulator.

In addition, not all bugs and performance problems can be caught through testing in Simulator alone. You’ll learn more about performance differences in Testing and Debugging in iOS Simulator. You can also find more information on testing your app on a device in Launching Your App on Devices in App Distribution Guide.

Quit Simulator

Simulator continues running until you quit it. Quitting Xcode will not close Simulator because they are separate applications. Similarly quitting simulator will not close Xcode.

To quit Simulator, choose Simulator > Quit Simulator. The device is shut down, terminating any running apps.

Note: Both Simulator and watchOS Simulator can be open at the same time.
