Input instructions on iOS

When a label might not describe the requested input sufficiently, you should add additional instructions. For example, if passwords are required to be at least 8 characters, indicate this to users.

On iOS, we recommend using an UILabel to indicate an error. The error message should also be posted to assistive technologies by using an accessibility announcement.

You could also use a third party library to displaying instructions. Unfortunately, accessibility is often not considered in the implementations.

helpLabel.isHidden = false
helpLabel.text = "Your password should be at least 8 characters."
