Hi, I am new to Xcode and just starting to write my first lines of code. When I start my app on the Simulator it works fine the first time. Sometimes one code change also works, but then I always run into problems. The Simulator does not update or run properly anymore.
I tried killing all Simulator processes, restarting xCode, stopping most other running apps, nothing worked but to reboot.
Anyone an idea what to do?
Here are two of the error messages that pop up:
Error message 1

I found the problem. I had the widget extension selected as target. And this would launch the app, but crash in subsequent calls. It also did not show any debug output. When I select the main app, it works fine. Only that I do not get the output of the extension in my log.
