What is NSTimeInterval?
TimeInterval (née NSTimeInterval ) is a typealias for Double that represents duration as a number of seconds.

- Use the scheduledTimer(timeInterval:invocation:repeats:) or scheduledTimer(timeInterval:target:selector:userInfo:repeats:)
- Use the init(timeInterval:invocation:repeats:) or init(timeInterval:target:selector:userInfo:repeats:)
Is TimeInterval in seconds Swift?
How do you convert milliseconds to seconds in Swift?
To convert milliseconds to seconds, divide the number of milliseconds by 1000 and then call the Date(timeIntervalSince1970:) with the resulting seconds. To avoid having to do this every time, you can write an extension to do it.
Is Swift TimeInterval in seconds?
What is time interval in Swift?
A TimeInterval value is always specified in seconds; it yields sub-millisecond precision over a range of 10,000 years. On its own, a time interval does not specify a unique point in time, or even a span between specific times.
How do I add hours and minutes in Swift?
- Use Calendar and date(byAdding:to:wrappingComponents:) . E.g., in Swift 3 and later: let calendar = Calendar.current let date = calendar.date(byAdding: .minute, value: 5, to: startDate)
- Just use + operator (see +(_:_:) ) to add a TimeInterval (i.e. a certain number of seconds).
How many minutes are in a year?
