It sounds like you're still using Xcode 9.2
as compactMap
is new in Swift 4.1
(which is bundled with Xcode 9.3
). You need to go into Software Update and update Xcode to 9.3
in order to build (as stated here).
If you keep running into build issues, try cleaning:
1) COMMAND-SHIFT-K before building
2) or, in Terminal: rm -rf ~/Library/Developer/Xcode/DerivedData/
before building
I had the same issue. An update of Xcode did fix this.
Yup, it's fixed! :)
