Annoying: Wireless debugging in Xcode sometimes fails to reconnect
Annoying: Wireless debugging in Xcode sometimes fails to reconnect

Issue

When you develop an App with Xcode on macOS you can test your app without the need for a cable. Once setup is done you can select your iPhone in Xcode and just hit the โ–ถ๏ธ Button. The app starts directly on your device, no cable required.

However, sometimes Xcode seems to forget how to reconnect to your device. I haven’t figured out the exact circumstances but I figured out a workaround.

Fix

If connections fails or takes very very long, try this:

  • Select an emulator (like iPhone 12 mini)
  • Start your app on that emulator
  • Wait for the Xcode debugger to connect (at least one line should be printed into the dev-console)
  • Kill the emulator
  • Select your device again
  • Hit play, be happy
