Could not build the application for the simulator. Error launching application on iPhone

[nelsonic]

Just tried to run our App on localhost with:

flutter run

Got:

Launching lib/main.dart on iPhone SE (3rd generation) in debug mode...

@LuchoTurtle were you able to run the App on the Simulator using iOS 17?

I'm using the physical iPhone S for testing. But I can get it to work on my simulator. Have you tried this comment? https://github.com/pichillilorenzo/flutter_inappwebview/issues/1735#issuecomment-1699023475

This seems to be related to the unwarranted XCode upgrade that was mentioned a few weeks ago.

Use the latest version of flutter_inappwebview. ie. flutter_inappwebview: ^5.8.0. They have fixed the issue in the latest version
