How set different widths for a UISegmentedControl's elements

Swift version: 5.2

Paul Hudson    @twostraws   

Segmented controls give each segment equal width by default, which is aesthetically pleasing when you have space to spare but technically irritating when space is tight. Rather than try to squash too much into a small space, you have two options: set custom segment widths, or ask iOS to size them individually for you.

The first option looks like this:

segmentedControl.setWidth(100, forSegmentAt: 0)
segmentedControl.setWidth(50, forSegmentAt: 1)

That gives you individually sized segments while sticking to a value you define, which means you get to tweak the aesthetics as you want. The second option looks like this:

segmentedControl.apportionsSegmentWidthsByContent = true

That hands full control over to iOS, which is probably the best thing to do most of the time.
