命令SwiftCompile失败，退出代码为非零

Question

我刚刚升级到XCode 14，用iOS 16测试我的应用程序，因为在UI中发现了一个bug，但它只是停止了编译(降级到以前的XCode版本13.4再次工作)。

下面是构建项目时的错误堆栈跟踪。

4.  While evaluating request ExecuteSILPipelineRequest(Run pipelines { Mandatory Diagnostic Passes + Enabling Optimization Passes } on SIL for EightUsersUI)
5.  While running pass #0 SILModuleTransform "SILGenCleanup".

Command SwiftCompile failed with a nonzero exit code

我尝试过删除和添加Swift包依赖项，但没有运气，清理了派生数据，重新启动了Xcode和mac。我没有主意了。

Answer 1

因为与其他类似的问题(如another compiler error )相比，我们的信息非常有限。您的编译器在SILModuleTransform阶段就死了。我建议您删除任何可疑的模块依赖项，并查看您的项目是否编译。顺便说一下，仔细检查模块，例如包/模块名不应该像任何类/结构的名称那样作为示例。
