TouchInspector
TouchInspector is a lightweight package that helps you visualize and debug touches on iOS and iPadOS.
Showing touches is super useful when recording and sharing demos from a device or Simulator.
TouchInspector can optionally also show hit-testing information (i.e. which view a touch is hitting). This is great when trying to identify the type of some view, or debug where a touch is actually going.
Installation
Add TouchInspector to your app's Package.swift file, or selecting File -> Add Packages in Xcode:
.package(url: "https://github.com/jtrivedi/TouchInspector", from: "0.1.0"))Usage
You'll need to change the type of your application/scene's window to TouchInspectorWindow, which you can do conditionally when developing:
import TouchInspector
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
guard let windowScene = (scene as? UIWindowScene) else {
return
}
let rootViewController = /* Create your root/initial view controller,
either directly or by extracting from a Storyboard */
#if DEBUG
window = TouchInspectorWindow(windowScene: windowScene)
#else
window = UIWindow(windowScene: windowScene)
#endif
window?.rootViewController = rootViewController
window?.makeKeyAndVisible()
}Touch and hit-testing visualization is enabled by default when creating a TouchInspectorWindow. You can change that with the following properties:
// Show the touch indicator, but not the hit-testing overlay.
window.showTouches = true
window.showHitTesting = false
