You no longer need to switch IDEs and have Xcode running to check that your code works correctly on both mobile platforms. With the new plugin, you get integration with your iOS device and simulator directly in Android Studio. This gives you the following capabilities:
• Run and debug the iOS application on the simulator or a device with the predefined run configuration.
• Run and debug common and iOS specific tests on the iOS simulator by simply clicking the gutter icon on a test class or method.
For both the application and tests you can set breakpoints and debug your code on iOS.
