Figure 1-1 Simulated iPhone running the HelloWorld appNote:В If you are testing an app with a deployment target of iPad, you can test only on a simulated iPad. 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. To run your app in Simulator, choose an iOS simulatorвЂ”for example, iPhone 6 Plus, iPad Air, or iPhone 6 + Apple Watch - 38mmвЂ”from the Xcode scheme pop-up menu, and click Run. Running Your iOS AppWhen testing an app in Simulator, it is easiest to launch and run your app in Simulator directly from your Xcode project. The first way is to run your app in Simulator, and the second way is to launch Simulator without running an app.

Figure 1-2 Simulated iPhone and watch Running Your tvOS AppTo run your tvOS App, choose a tvOS device from the Xcode scheme pop-up menu. Figure 1-2 shows an iPhone 6 and a 42mm watch running in two different simulators. 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.

There are two ways to access the Home screen in Simulator from your app:Use the installed apps to test your appвЂ™s interaction with them. View the Installed AppsFrom the Home screen, you have access to all of the apps that are installed in the simulation environment. 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 appChoose 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 appChoose 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. Figure 1-3 Simulating tvOS Launching Simulator Without Running an AppAt times, you may want to launch Simulator without running an app.

See iOS Device 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. After clicking the Home button (or accessing the Home screen through the Hardware menu), you arrive at the second page of the Home screen. IOS Device Home ScreenMuch like the Home screen on an iOS device, the simulatorвЂ™s iOS Home screen has multiple pages.

You can click and drag to simulate the finger dragging around the screen and launch an app by clicking on it. WatchOS Device Home ScreenThe Home screen for a simulated watchOS device behaves the same as it would on an actual device. Because Passbook and the Health app are available only for the iPhone, these apps donвЂ™t appear if you are simulating a legacy device or an unsupported device type.

For example, type apple.com into the address field and press Return. Use Safari to test your iOS web apps directly on your Mac.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. Figure 1-5 Home screen for a simulated watchOS device Use Safari to Test Web AppsFrom the Home screen, you can access Safari within Simulator.

Figure 1-7 Running Maps and simulating a latitude and longitude in Simulator Change the Simulated Device and OS VersionSimulator provides the ability to simulate many different combinations of device type and OS version. 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.Choose Debug > Location > Custom Location.In the window that appears, type the number 40.75 in the latitude field and the number -73.75 in the longitude field.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. Set a location by choosing Debug > Location > location of choice. One of the many features you can debug in Simulator is location awareness within your app. Figure 1-6 The Apple website running in Safari in Simulator Use Maps to Simulate Location AwarenessSimulator provides tools to assist you in debugging your apps.

To open the Settings app, go to the Home screen and click or on tvOS, choose Settings. Alter the Settings of the Simulated DeviceYou can alter the settings within Simulator to help test your app.On a simulated device, use the Settings app. The new device goes through a normal OS startup sequence.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.Choose Hardware > Device > Manage Devices.At the bottom of the left column, click the Add button (+).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.Choose the OS version from the iOS Version pop-up menu.Alternatively, if the iOS version you want to use isnвЂ™t in the iOS Version pop-up menu, choose вЂњDownload more simulatorsвЂќ and follow the steps to download a simulator.If the OS version you want to use is not installed, download it and follow the steps to add a simulator again.In the Preferences window, click Downloads.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.In Simulator, choose Hardware > Device > Manage Devices, or in Xcode, choose Window > Devices.In the left column, select the simulator.At the bottom of the left column, click the Action button (the gear next to the Add button).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. The existing device goes through a normal OS shutdown sequence, though the timeout might be longer than the one on a real device.
