The tiny paired arrows are the stepper — click, or hold for autorepeat
Stepper
/ NSStepper · Stepper /
also called stepper control, stepper arrows, numeric stepper, incrementer
A stepper is a pair of small stacked arrow buttons for changing a value by a fixed increment. It commonly sits beside a numeric text field so users can either type an exact value or adjust it one step at a time. Its enabled states should reflect the configured minimum and maximum, and holding an arrow can repeat the change.
Anatomy — every part, named
- 1Increment button
NSStepper.increment“The tiny upper arrow that raises the number” is the increment button.
- 2Decrement button
NSStepper.increment“The tiny lower arrow that reduces the number” is the decrement button.
Prompt — paste into your agent
Place a native Stepper using NSStepper (SwiftUI: Stepper) beside the numeric field, with the compact up/down arrow pair vertically aligned to that field. Bind both controls to the same value and enforce the intended increment, minimum, and maximum.
