问题：
因为升级了Macos系统->15.2导致旧版的xcode无法使用，只能升级了xcode到最最新版(16.2.0)，升级完以后运行flutter报错：
Running pod install...

Running Xcode build...

我目前的版本如下：
#flutter version:
Flutter 3.22.3 • channel stable • https://github.com/flutter/flutter.git
Framework • revision b0850beeb2 (6 months ago) • 2024-07-16 21:43:41 -0700
Engine • revision 235db911ba
Tools • Dart 3.4.4 • DevTools 2.34.3
#xcode version
16.2.0
#pod version:
1.16.2
#xcodeproj version
1.27.0
如果还是无法解决问题
打开Xcode 16
修改 Allow Non-modular includes in Framework Modules -> Yes
可以搜索关键字CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES进行修改
