  • SR-2189 Nested function with local default value crashes

Issue Description:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: can't open input file: /Users/***/Library/Developer/Xcode/DerivedData/****-hfmagvhgn/Build/Intermediates/****.build/Debug-iphonesimulator/*****.build/Objects-normal/i386/****** (No such file or directory)

Compiler crash when a nested function uses as default value of one of the argument, a variable declared in the parent scope.

The crash happens only if the inner function is called with the default argument

This compilation issue (if real) should be highlighted as a real-time compilation issue instead of crashing at build time?

// This Works fine
  var testVariable: String {
    let iWillMakeTheCompilerCrash: String = "the crashing variable"
    
    func innerFunctionWithDefaultArgument(iCrashOnCompilation: String = "") {
    
    }
    
    innerFunctionWithDefaultArgument()
    
    return ""
  }
// This will crash due to the default variable

  var testVariable: String {
    let iWillMakeTheCompilerCrash: String = "the crashing variable"
    
    func innerFunctionWithDefaultArgument(iCrashOnCompilation: String = iWillMakeTheCompilerCrash) {
    
    }
    
    innerFunctionWithDefaultArgument()
    
    return ""
  }
