How to convert TimeInterval to CMTime in Swift 4?

Question

I can’t seem to figure out how to convert TimeInterval to CMTime. Does it need more than just a simple conversion method?

Answer 1

You can write something like this:

let timeIntvl: TimeInterval = 60
let cmTime = CMTime(seconds: timeIntvl, preferredTimescale: 1000000)

1000000 represents that the preferred Timescale is 1μsec (1/1000000 sec).

When you convert between some types, there's usually no simple conversion method and you may need to find an initializer of the destination type.

init(seconds: Double, preferredTimescale: CMTimeScale)
