升级xcode15遇到的问题

写在最前
升到mac os 14 ，xcode 14.3.1就不给用了，必须使用xcode 15+，所以遇上问题必须解决，尤其是引入了一下小公司的SDK，更新不及时，所以慎重升级。

1. 编译报错 DT_TOOLCHAIN_DIR cannot be used to evaluate LIBRARY_SEARCH_PATHS, use TOOLCHAIN_DIR instead

Podfile最后加上以下代码 并pod install

post_install do |installer|
  installer.generated_projects.each do |project|
    project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'  
         end
    end
  end
  
  installer.aggregate_targets.each do |target|
    target.xcconfigs.each do |variant, xcconfig|
      xcconfig_path = target.client_root + target.xcconfig_relative_path(variant)
      IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
    end
  end
  
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.base_configuration_reference.is_a? Xcodeproj::Project::Object::PBXFileReference
        xcconfig_path = config.base_configuration_reference.real_path
        IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
      end
    end
  end
   
end

2.个推报错
升级到最新，并且只支持iOS 12+
