尝试在设备（iPad）上运行我的代码时，我反复收到错误。一个错误，在其巨大的描述结束时说 命令/Volumes/Xcode/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang失败，退出代码为254
每次切换到从模拟器运行到设备时，我都需要清理，删除派生数据，退出并重新启动xcode。 下面是完整的错误描述 -

设备或任何其他东西是否有任何问题，如果您知道帮助，有人会找到答案。 感谢
答案 0 :(得分：1)
我遇到了类似的错误。在我的情况下，清理项目并删除构建和派生数据完成了这项工作。
答案 1 :(得分：0)
我想通了，它只是一个链接错误，只是重建项目解决了问题。感谢
