Issue Description:
Under Xcode 9 / Swift 4.1, it was possible to construct an NSError with the appropriate domain and code and have it bridge to a CLError using an as? cast in Swift. This causes a crash in Xcode 10 / Swift 4.2.
To reproduce, run the attached playground in Xcode 10. It contains this code:
import CoreLocation
let error = NSError(
domain: kCLErrorDomain,
code: CLError.geocodeFoundNoResult.rawValue)
error.localizedDescription
error is CLError
error as? CLError
