Xcode Cloud构建本地SPM报错：检测到过时的Package.resolved文件

问题重现 #

本地基于Apollo iOS SDK v1.9.0添加了2个Swift包，通过Xcode管理依赖，本地构建正常，但Xcode Cloud构建时报错：

Could not resolve package dependencies:
an out-of-date resolved file was detected at /Volumes/workspace/repository/Play.xcworkspace/xcshareddata/swiftpm/Package.resolved, which is not allowed when automatic dependency resolution is disabled; please make sure to update the file to reflect the changes in dependencies. Running resolver because the following dependencies were added: 'myPackage' (/Volumes/workspace/repository/MyProject/MyPackage)
fatalError

解决方案 #

• 强制刷新本地依赖缓存并重新提交
  打开Xcode，依次执行：File > Packages > Reset Package Caches，完成后再执行File > Packages > Resolve Package Versions。检查Package.resolved文件是否有变更，将最新版本提交并推送到远程仓库。

• 核对Xcode Cloud的依赖解析配置
  进入项目设置：Project > Project Settings > Package Dependencies，查看Automatic Dependency Resolution的状态。如果项目禁用了自动解析，确保本地Package.resolved完全匹配当前依赖状态；也可以尝试临时启用自动解析，重新生成Package.resolved后再禁用，或者保持启用（如果项目允许），让Xcode Cloud自动处理依赖版本。

• 确保本地包使用相对路径
  检查添加本地Swift包时的路径配置：添加包时选择Add Local...，确保选择的是项目根目录下的包文件夹，而非绝对路径。Xcode Cloud的工作区路径与本地不同，绝对路径会导致依赖找不到，进而触发resolved文件过时的错误。

• 重新添加本地Swift包
  先从Package Dependencies中移除这两个本地包，清理项目缓存后，重新添加本地包，再次执行依赖解析，提交更新后的Package.resolved。

• 确认Package.resolved已正确提交
  用终端执行git status查看文件状态，git log --oneline检查提交记录，确保Package.resolved已经被添加到git仓库并推送到远程分支，避免Xcode Cloud拉取代码时缺少该文件。
