I set up a new flutter project with flutter create, and it looks like the “UiKit.h not found” is a general issue with Xcode 15.3 … I will update on that once I solved it.
So, in the new project I removed cocapods 3rd party libs.
I use the same flake posted above:
Xcode 15.3, flutter 3.19
and ran
flutter create new_flutter
flutter build ios
so a pretty striped-down setup, but get this error:
Error (Xcode): Target debug_unpack_ios failed: Error: Flutter failed to create a directory at
"/nix/store/09v9fm2zq664rhdnbvyg2wr9j4j7ak2i-flutter-3.19.0-unwrapped/bin/cache/artifacts".
Now I am looking why this happens besides a solved issue and if I can symlink the cache directory myself using nixpkgs.config.lib.file.mkOutOfStoreSymlink.
I will keep updating here - but if anyone has any pointers I would be very grateful
