QUESTION
I've got a precise timer that needs to be update every 40ms (most precisely than possible). On iOS10 it's good (I use the new scheduleRepeating
method) but on iOS9 I need to use the old way (scheduledTimer
) and it's pretty laggy (sometimes 24ms, sometimes its 72...), so my hardware interface and visual effects and lagging.
Any suggestion?
...ANSWER
Answered 2017-May-19 at 09:48From Apple doc about NSTimer
:
A timer is not a real-time mechanism. If a timer’s firing time occurs during a long run loop callout or while the run loop is in a mode that isn't monitoring the timer, the timer doesn't fire until the next time the run loop checks the timer. Therefore, the actual time at which a timer fires can be significantly later. See also Timer Tolerance.
If you want a very precise timer you can check an implementation from Apple Tech Note and adapt in Swift or use a CADisplayLink
for display updates.
QUESTION
I have created a simple timer in swift 3.
For some reason though, even though it works the label display too many numbers :S it displays a crazy amount of 9's. Is this to do with rounding?
Thanks, code below :)

instead of round(swiftCounter)
