Xcode also lets you alter the settings available on the simulated device, depending on the device and iOS version, to see how those settings affect your app. For example, you can test how your app behaves when the screen is rotated to make sure it works in both portrait and landscape modes. If you want to dig deeper into using Xcode to test your app, check out the Xcode Help guide from Apple. Xamarin gives you access to important iOS tools like ARkit, Core ML 2, Siri Shortcuts, and Touch ID. While Xamarin requires a Mac to fully function, using it on a Windows device offers some benefits. For example, if you have a Windows touch-screen device, you can interact with the simulator or use shake gestures as if you were using an actual iPhone. You can pinch, swipe, take screenshots, and even use multi-finger touch gestures.
