I updated Xcode and MacOS recently and haven’t been able to compile my Flutter app on iOS devices/simulators since then. The error keeps changing every time I run it but here’s one of the output in the terminal after running flutter run:

What I have tried so far:
- Deleting iOS SDK and simulators
- Cleaning Xcode build cache using
cmd+shift+k - Creating a new Flutter project and trying to compile it (it failed so that reduces the chances of it being a Flutter issue)
- Clearing the DerivedData folder
- Clearing settings and cache of simulators
- Restarting laptop
Versions:
- Xcode: 16.0
- iOS: 18.0
- MacOS: 15.1 (didn’t work with 15.0 either)
- Flutter: 3.24
I have found a workaround – change the location of DerivedData folder in Xcode Workspace settings (File -> Workspace Settings) to something else.
