今天讲使用Xcode Build and Run your app，你可以使用模拟器，也可以使用真机进行编译和运行。

Build and run your app

Build and run your code to compile, link, and debug it. For products that can be run directly, if the product builds successfully Xcode runs the product and starts a debugging session.



1.Optionally, select an active scheme and destination from the scheme menu in the toolbar.

For iOS, watchOS, and tvOS apps, choose a run destination from the Scheme menu.

To run in a simulator: Under iOS Simulators, choose a device family or click Add Additional Simulators to configure your own. For tvOS apps, choose Apple TV 1080p.

To build using the platform SDKs: Under Build Only Device, choose a generic device. Choose a generic device if later you want to create an archive of your app and you don’t have a real device. You can’t create an archive of a simulator build.

To launch on a device: Under Device, choose a device connected to your Mac.



2.Click the Run button to build and run your code with the active scheme.

The activity viewer shows the build progress and results. (If the device is not registered, click Register Device in the sheet that appears.)

3.Use the Stop button to stop an in-progress build or end the current debugging session.

Xcode displays any errors or warnings it encounters in the issue navigator. If there are errors during the compilation or link phase, Xcode does not run your code.
