I'm not iOS developer but started learning Swift.
I try to convert some logic from Android project to iOS.
I have the following method:
func addGroupItemSample(sample : WmGroupItemSample){ // some custom class
var seconds: NSTimeInterval = NSDate().timeIntervalSince1970
var cuttDate:Double = seconds*1000;
var sampleDate: UInt64 = sample.getStartDate(); // <-- problematic place
if(sampleDate > cuttDate){
// ....
}
}
From the method above you can see that sample.getStartDate()
returns type UInt64
.
I thought it's like long
in Java: System.currentTimeMillis()
But current time in milliseconds defined as Double
.
Is it a proper way to mix Double
and UInt64
or do I need to represent all milliseconds as Double
only?
Thanks,
in iOS it is better to use double, but if you want to easy port your code and keep it consistent you can try this:
func currentTimeMillis() -> Int64{
let nowDouble = NSDate().timeIntervalSince1970
return Int64(nowDouble*1000)
}
