Hi,
I have one question how to use the unity "seconds" in a Swift Playground.
I coded a countdown and want to make it as an countdown for 30 seconds.
The source code is quiet easy:
var countdown = 30
var start = 1
func countdown_running(value: Int) {
while start <= value {
print(start)
if start == 30 {
print("Finished")
}
start += 1
}
}What I have to submit for counting seconds?
Thank you for your help!
Then Playgrounds is the right place to post. But it's not a big issue, moderator of the forums will move this thread if he/she thinks it's needed.
I do not understand what you mean with `unity`, but when you want to implement sort of countdown timer, you use `Timer`.
In the Xcode Playground, you can write something like this.
import Foundation
import PlaygroundSupport
PlaygroundPage.current.needsIndefiniteExecution = true
var countdown = 30
var start = 1
let timer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { timer in
if start <= countdown {
print(start)
start += 1
} else {
print("Finished")
timer.invalidate()
}
}Seems it's a countup timer.
You mean Swift Playground on iPad, not Xcode Playground on mac?
(Just for confirmation, the code needed may not be much different.)
No, I want to create a Xcode Playground on Mac.

Thank you! It works!
Sorry for the language and understanding mistake - I'm new in App Development and the Community and of course, you see, English is not my mother ******...
But thanks for you feedback - I try to improve it all the time :-)!
