Hello, I am trying to define an operator that subtracts dispatch times:
#import Dispatch func -( time1: DispatchTime, time2: DispatchTime ) -> DispatchTimeInterval { return DispatchTimeInterval.nanoseconds( time2.uptimeNanoseconds - time1.uptimeNanoseconds ) } Compiler says: Ambiguous use of operator ‘-' Found this candidate Found this candidate As usual the candidates are unknown. What am I doing wrong? Jan E. _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
