python – xcrun “iphonesimulator” error after running toolchain build kivy

I’m building a mobile app with Python and Kivy and I want to compile it for iOS.

I have:

• kivy-ios installed
• Python 3.9
• Xcode 13.2
• Xcode command line tools
• macOS 11.7.10

I followed the guidelines in the official kivy documetation: https://kivy.org/doc/stable/guide/packaging-ios.html

And I managed to get to the toolchain part.

When I run the toolchain build kivy command in the macOS terminal, I’m getting this error:

  STDERR:

Does someone know how to fix this ?

I’ve saw that some people said that in this case you need to go in the Xcode preferences/settings section and do some stuff but I can’t find them on my Xcode version.

Maybe the problem is elsewhere.
