Switches on the iPhone turn green when they are on. If green and grey are hard to tell apart, the switches can carry a symbol too: a line for on, a circle for off.
The screenshots show iOS 26.5 on an iPhone 17. On older versions the rows have the same names, with a slightly different look.
Step by step
Open Settings and tap Accessibility
Accessibility is in the first group of the main Settings list, below General.
Tap Display & Text Size
It is in the Vision group, below Hover Text.
Switch on On/Off Labels
It is the fourth row of the page. In the picture it is off, and the small circle is already visible inside the switch.

In short: Settings, Accessibility, Display & Text Size, On/Off Labels on.
