Text fields
Best practices
Use a text field to request a small amount of information, such as a name or an email address.
Show a hint in a text field to help communicate its purpose.
Use secure text fields to hide private data.
To the extent possible, match the size of a text field to the quantity of anticipated text.
Evenly space multiple text fields.
Ensure that tabbing between multiple fields flows as people expect.
Validate fields when it makes sense.
Use a number formatter to help with numeric data.
Adjust line breaks according to the needs of the field.
Consider using an expansion tooltip to show the full version of clipped or truncated text.
In iOS, iPadOS, tvOS, and visionOS apps, show the appropriate keyboard type.
Minimize text entry in your tvOS and watchOS apps.
Platform considerations
iOS, iPadOS
Display a Clear button in the trailing end of a text field to help people erase their input.
Use images and buttons to provide clarity and functionality in text fields.
macOS
Consider using a combo box if you need to pair text input with a list of choices.
watchOS
Present a text field only when necessary.
