如何正确签署包含.dylib文件的xcframework？

问题背景 #

开发一款带C兼容接口的跨平台C++库，目标打包为XCFramework分发。使用CMake编译并单独签署各平台二进制文件后，通过xcodebuild -create-xcframework生成XCFramework。仅iOS物理设备加载库时出现签名错误，模拟器、macOS及Catalyst环境下无异常。

当前构建命令 #

生成XCFramework的命令：

xcodebuild -create-xcframework -library builds/catalyst/Release/mylib.1.1.0.dylib -headers include -library builds/macos/Release/mylib.1.1.0.dylib -headers include -library builds/ios/Release/mylib.1.1.0.dylib -headers include -library builds/ios-sim/Release/mylib.1.1.0.dylib -headers include -output Mylib.xcframework

排查情况 #

• 单独检查各.dylib文件，签名状态均正常
• 尝试遵循官方指南使用Xcode归档，执行命令：

  xcodebuild archive -project Mylib.xcodeproj -scheme Mylib -destination "generic/platform=iOS" -archivePath "archives/Mylib" SKIP_INSTALL=NO BUILD_LIBRARY_FOR_DISTRIBUTION=YES
  

  但归档产物的文件结构中出现可疑的@rpath目录：

  .
  └── Mylib_iOS_Simulator.xcarchive
      ├── Info.plist
      ├── Products
      │	└── @rpath
      │	    └── mylib.1.1.0.dylib
      └── dSYMs
