flutter踩坑插件:Swift架构不兼容

最近接手一个老项目,净是遇到插件swift架构不兼容,报错如下:

Could not build the application for the simulator.

网上查一堆资料,也问了很多次AI都解决不了,也不知道啥问题,怀疑是mac 的m1、m2芯片的虚拟机和m4芯片的不一样,博主是M4。

废话不多说,下面是解决方案:

在ios下的Podfile文件中添加如下代码:

复制代码
# 添加以下配置来解决Swift架构问题
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '15.6'
      config.build_settings['SWIFT_VERSION'] = '5.0'
      config.build_settings['ENABLE_BITCODE'] = 'NO'
      
      # 关键:排除模拟器的arm64架构
      config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64'
      
      # 确保支持正确的架构
      config.build_settings['VALID_ARCHS'] = 'arm64 x86_64'
      config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'

然后完全清理并重建:

复制代码
# 停止所有Flutter进程
flutter devices
# 如果有设备在运行,先停止

# 清理Flutter缓存
flutter clean

# 删除iOS构建缓存
cd ios
rm -rf Pods Podfile.lock
rm -rf ~/Library/Developer/Xcode/DerivedData
cd ..

# 重新获取依赖
flutter pub get

# 重新安装Pods
cd ios
pod install --repo-update
cd ..

最后再运行,就OK了

我的完整Podfile:

复制代码
# Uncomment this line to define a global platform for your project
platform :ios, '15.6'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
 

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  target 'RunnerTests' do
    inherit! :search_paths
  end
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    
    # 添加以下配置来解决Swift架构问题
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '15.6'
      config.build_settings['SWIFT_VERSION'] = '5.0'
      config.build_settings['ENABLE_BITCODE'] = 'NO'
      
      # 关键:排除模拟器的arm64架构
      config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64'
      
      # 确保支持正确的架构
      config.build_settings['VALID_ARCHS'] = 'arm64 x86_64'
      config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'
    end
  end
end
