in swift 3 syntax of gcd has changed quite bit. a call dispatch_after() looks this: dispatchqueue.main.asyncafter(deadline: .now() + 5.0) {//do something} that code invoke block 5 seconds after it's called. how work? docs deadline parameter dispatch_time_t , typealias uint64. assume it's mach time in nanoseconds. however, .now() + delay syntax adding decimal seconds value. doesn't dispatchtime.now() return uint64 ? if so, adding decimal seconds should not work. if anything, expect value added .now() treated nanoseconds, not useful. (in swift 2 used have multiply value constant number of nanoseconds per second.) ok, found answer own question in thread: how write dispatch_after gcd in swift 3? apparently there override of + operator takes dispatchtime , double, treats double decimal seconds, , returns resulting dispatchtime .
