Please can someone explain to me how to stop a scheduled timer in latest swift version.

Question

Timer.scheduledTimer

I used to stop it with. Timer.invalidate()
But this no longer seems to work.

I’m trying to have a start button to make the label display and add +1 each 3 seconds. Then I want a stop button to just stop the timer.

Most appreciated if someone could explain the simplest way to achieve this.

Thanks team

Answer 1

i figured it out tial and error style
i used var stopNum
then inside the timer {} i used
if stopNum >= 1 {
Timer.invalidate()
}
then inside the stop button i used stopNum += 1

now when i hit stop it adds 1 and triggers the invalidate()

thanks for your answer though most appreciated im attempting to make a bitcoin bot for auto trading so many more problems infront of me :)

Answer 2

It should still be invalidate()

Are you perhaps re-firing the timer?
Is the timer is scope of invalidate()?

Glad you got it sorted out
