Last week when I last worked on this it was building ok.
Stopped working on this while adding new feature to an other app, week-end break I come back and both app do not compile any more. one is complaing that it as a socket exeception, and the other one as the below problem.

Could not build the precompiled application for the device.
Lexical or Preprocessor Issue (Xcode): 'Flutter/Flutter.h' file not found

Uncategorized (Xcode): Command SwiftEmitModule failed with a nonzero exit code


Error launching application on AR18 iPhone.

I tried the usual stuff DT_TOOLCHAIN_DIR cannot be used to evaluate LIBRARY_SEARCH_PATHS, use TOOLCHAIN_DIR instead in xcode 15
I even asked GPT for some help. Nothing as worked.

So to make a quick list.
-fully remove the cocoa pods, re-istalled them and update the repo.

• delete the ios folder to re-generate it.. a few times (just in case).
• cleaned, and cleaned flutter and ios projects.
• deleted xcode cache files.
• change my pod file (see below)

Still not able to get the app to build.
