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.
