However, in this case I think the issue is that the candidates weren’t from user code but from the standard library, which Xcode has all sorts of issues navigating within, seemingly at random.<br>
As an aside, it would be really cool if, instead of seeing the standard library as a compiled module, Xcode could navigate to the relevant source code (perhaps optionally). Otherwise I’m stuck either looking at documentation (Apple’s docs or swiftdocs) and if that doesn’t help, trying to navigate to the relevant code in GitHub. This is especially true for things like finding out what the default values defined for functions are, as the documentation just shows default, which is useless.<br>
