Flutter app does not compile with Xcode 15

[srinivas-codezyng]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

Compile a Flutter app with Xcode 15 in Code magic

Expected results

It should compile and .ipa should be generated

Actual results

Gives a compiler error with following error :

Running Xcode build...

Encountered error while archiving for device.

Note that the issue happens in the local machine as well with Xcode 15. This solution worked pichillilorenzo/flutter_inappwebview#1735 (comment). As this require changing a SDK file and requires sudo access. How do we do it in the CD machine? or is there any workaround for the issue?

hey @srinivas-codezyng i recently also had compiling issues with xcode 15, but I tried with the newly released cocoapods 1.13.0 version, and it fixed my problems..

try defining inside your yaml the build environment like this;

    ios-workflow:
      name: iOS Workflow
      instance_type: mac_mini_m1
      max_build_duration: 120
      integrations:
        app_store_connect: testscodemagic 
      environment:
        xcode: 15
        cocoapods: 1.13.0
        flutter: stable

Thanks @dtrdic for the response. I did have couple of issues. Updating to cocoapods 1.13.0 version only fixed the Error: DT_TOOLCHAIN_DIR cannot be used to evaluate LIBRARY_SEARCH_PATHS.
Issue related to

hey @srinivas-codezyng looks like it was just released a patch version that you can try to use

I'm already running on 1.13.0 and still having the same error

I fixed all my Xcode 15 issues with flutter by going into [System Settings -> General -> Storage -> Developer -> & Delete the XCode Cache]
