relates to:

  • SR-7879 UIEdgeInsets.zero use crashes Xcode 10/Swift 4.2 compiler

Issue Description:

Any reference to NSPasteboard.PasteboardType.findPanelSearchOptions crashes the compiler. All other cases of the same enum seem to work fine.

Same error output, but caused by a different imported API. It's been resolved, but its solution doesn't fix this issue

Yeah, SR-7879 was a narrow fix. We've done some more general work since then, so this might be fixed by now as well. I'll take a look.

Nope, different issue, caused by AppKit having both NSFindPanelSearchOptionsPboardType and NSPasteboardTypeFindPanelSearchOptions.

@belkadan Hey Jordan, do you have a fix in mind?

I'm talking with AppKit. Meanwhile, you can either keep compiling in Swift 4 mode, or write a little Objective-C helper function that returns the constant rather than going through the property.
