Buy me a coffee!

If this was useful to you, buy me a coffee to make my day!

What does it take?

• XCode 11.6
• SwiftUI
• To build a WatchKit application for a device, you first need to have an Apple Watch that’s paired with an iPhone. When you build and install the app, you’re actually building and installing an iOS app, and the watchOS app it contains is then copied to the Apple Watch.

HOWTO debug the iOS part of Apple Watch app in the Simulator

1. Select the WatchKit App target then click the Run icon. Xcode will install the iOS app, without launching it, then will install and launch the WatchKit app.

2. Select the iOS App target and click the Run icon. Xcode will install the iOS app again, but will also launch it, attaching it for debugging.

3. Finally, in the debug Xcode panel at the bottom, click on the target icon (next to the appearance icon), which is actually a popup button, to choose which of both targets should display its debugging output.
