There is a new API in iOS 16 that makes it easier to deal with and measure time.

Here’s a simple Form that uses two kinds of clock: a SuspendingClock, which stops when the app enters the background, and a ContinuousClock, which... continues.

Each clock has a Stepper to choose the amount of time you want to wait and a Button that starts the wait.

Clocks.swift

As the sleep function can throw, I am wrapping it in a do-catch, and it is inside a Task because otherwise the closure would be asynchronous and unsuitable as the action of a Button.
