Question

xcodebuild因以下错误而失败：

<unknown>:0: error: unable to execute command: Segmentation fault: 11
<unknown>:0: error: merge-module command failed due to signal (use -v to see invocation)
** BUILD FAILED **


The following build commands failed:
    MergeSwiftModule normal arm64 /Users/vmanot/Documents/Xcode/Projects/Frameworks/ExSwift/build/ExSwift.build/Release-iphoneos/ExSwift.build/Objects-normal/arm64/ExSwift.swiftmodule
    CompileSwiftSources normal arm64 com.apple.xcode.tools.swift.compiler
(2 failures)

（上面提到的ExSwift不是开源ExSwift，而是私有框架。

如何找到错误的代码？

Answer 1

我认为此错误的来源可能会有很大差异，取决于您编写的Swift源代码。我在尝试为符合UIPickerViewDataSource的自定义协议编写扩展时收到此错误。具体来说，我正在编写numberOfComponentsInPickerView(_:)和pickerView(_:numberOfRowsInComponent:)的默认实现。

我还没有确认，但我怀疑我们遇到的错误与Objective-C互操作性有关。我所知道的只是将这些实现从协议转移到符合要求的类中为我修复了错误。

编辑：更改优化级别，因为Bruno建议没有帮助。
