    Updated 11 Oct 2023 Solutions If you faced an issue after updating to Xcode 15 and can’t run your flutter app on iOS platform. Follow the solutions below.

    Solution 1: Update Cocoapods to v1.13 (1.13 released a fix)

    It seems to be an issue due to old Cocoapods version with Xcode 15. This is resolved in the CocoaPods version 1.13.0

    You can follow these steps https://stackoverflow.com/a/77229768/6890699

    Solution 2: Update Podfile (Flutter / Xcode 15)

    However, it’s important to note that this should only be used as a temporary solution until a cocopods update comes out that fixes your Xcode version

    post_install do |installer|
  installer.pods_project.targets.each do |target|
     flutter_additional_ios_build_settings(target)
      target.build_configurations.each do |config|
        xcconfig_path = config.base_configuration_reference.real_path
        xcconfig = File.read(xcconfig_path)
        xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
        File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
      end
  end
end

    For non-flutter users: Remove the below line from the script.

    flutter_additional_ios_build_settings(target)

    Additional fixes related: Update flutter libraries

    If you use inAppWebview, you will get an error like this

    Parse Issue (Xcode): Could not build module ‘WebKit’

    Update inAppWebview to v5.8.0 release

    flutter_inappwebview: 5.8.0

    Look for updates on the libraries you are using within your flutter project.

    REMEMBER after using any of the above solutions

    1. Clean your flutter project flutter clean && flutter pub get
    2. Remove Pods directory inside iOS directory rm Podfile.lock && rm -rf Pods/
    3. Install and update pods pod install && pod update
    4. Build and test your app on an ios device flutter run or build within your Xcode.
