This post is from the WWDC26 UIKit Q&A.

What is the expected behaviour of UISlider.TrackConfiguration.Tick's title and image properties?

On iOS, these seem to be no-ops. The docs also don't indicate what these properties do.

let ticks = [
    UISlider.TrackConfiguration.Tick(position: 0, title: "Slow", image: UIImage(systemName: "tortoise.fill")),
    UISlider.TrackConfiguration.Tick(position: 1, title: "Fast", image: UIImage(systemName: "hare.fill"))
]

let configuration = UISlider.TrackConfiguration(ticks: ticks)

let slider = UISlider()
slider.trackConfiguration = configuration

These do not currently show in the UI on iOS but are reserved for adding functionality such as enhanced accessibility or context without requiring a deprecation of the existing API.

It is worth noting, as well, that not all APIs like this behave exactly the same on all platforms. For example, UISwitch has a title option that only applies visually on macOS.
