That error is completely wrong. The block passed to Objective-C does not escape. It is called, not retained, and the function exits.
This looks like a bug in Swift 4.2's runtime checking. In any case, I'll have a look this evening and see if I can find a work-around.

According to Swift developer Joe Groff, this is a confirmed Swift 4.2 bug.

I'll still look for a workaround since I have no idea how long it will take this issue to be resolved in Xcode.

Yes, this is a Swift compiler bug (I and @phatblat are the reporters of this in the Swift lab).
Current workaround is Quick/Nimble#537.

The fix for the compiler bug is somehow included in Xcode 10 beta 3 (Quick/Nimble#560), so I'm closing this.
