GitLab CI+Fastlane上传App遇iOS SDK版本验证错误求助

使用GitLab CI配合Fastlane上传iOS应用时，持续出现以下验证错误：

本地环境已更新至最新版本：

• macOS 14（Sonoma）
• Xcode 15.3
  且Mac上仅安装了Xcode 15和iOS 17 SDK，应用为iOS平台应用。为何仍提示基于iOS 16.2 SDK构建？该如何解决此问题？

1. 确认GitLab CI Runner的Xcode环境 #

本地环境正常不代表Runner环境正确，重点检查Runner端：

• 在CI脚本中添加xcodebuild -version命令，输出当前使用的Xcode版本，确认是15.3
• 执行xcodebuild -showsdks查看已安装的SDK列表，确认包含iOS 17.x SDK
• 若Runner存在多个Xcode版本，在CI脚本开头添加xcode-select -s /Applications/Xcode_15.3.app切换到正确版本路径

2. 验证项目构建设置 #

CI环境可能读取到旧的缓存设置，需明确指定SDK：

• 在CI脚本中先执行xcodebuild clean或Fastlane的clean动作，清理旧构建产物
• 用xcodebuild -project YourProject.xcodeproj -showBuildSettings | grep SDKROOT查看实际使用的SDK路径，确认指向iOS 17 SDK
• 检查项目的Base SDK配置，确保设置为Latest iOS或明确选择iOS 17.x

3. 调整Fastlane配置 #

Fastlane的gym动作可能未指定正确SDK：

• 在Fastfile的gym配置中添加sdk: "iphoneos17.3"参数，强制指定构建所用SDK
• 更新Fastlane到最新版本：bundle update fastlane，避免旧版本的兼容性问题

4. 清理CI环境缓存 #

旧缓存可能导致构建时使用旧SDK：

• 在CI脚本中添加清理DerivedData的命令：rm -rf ~/Library/Developer/Xcode/DerivedData
• 检查GitLab CI的缓存规则，确保未缓存旧的构建产物或构建设置文件

5. 处理DNS解析错误 #

日志中附带的DNS错误可能影响上传流程：

• 确认Runner所在网络能正常访问App Store Connect相关域名
• 可尝试在CI脚本中添加DNS刷新操作，或切换到公共DNS服务器
