Repeating Clock

I’m trying to build a clock app that has multiple hourly countdowns plus the time.
I have the time displayed properly but I can’t find a way to simplify the code to compare the minutes of the hour, without writing a line for every hour.
Is there a way to just use minutes to trigger?

maybe you can use swift timers to “check” and compare the times at a defined interval? https://codewithchris.com/swift-timer/
