Token Field
A Token Field turns each known value into a separate item that can be removed. People can keep typing to add more values.
A real example
An email field turns each valid address into a token. It marks an invalid address before sending.
Main parts
- 01Persistent label
- 02Input control
- 03Hint or format
- 04Validation message
Use it when
Use it for several structured values that the app can find, check, fill in, select, and remove one by one.
Do not use it when
Do not turn free writing or one value into tokens. Each item needs a clear label and room for any error message.
Name used in code
AppKit NSTokenField Before you ship
Check the supported macOS versions and AppKit or SwiftUI integration. Check standard focus and keyboard behavior. Also check VoiceOver, Full Keyboard Access, window resizing, and multi-window state. When needed, check restore, localization, and reduced motion.
Outcome: Apply or review Token Field in a native macOS app without breaking platform rules. User context: An email field turns each valid address into a token. It marks an invalid address before sending. macOS concept or control: Token Field. Why it fits: Use it for several structured values that the app can find, check, fill in, select, and remove one by one. Do not use it when: Do not turn free writing or one value into tokens. Each item needs a clear label and room for any error message. Platform requirements: List the supported macOS versions. Say whether AppKit or SwiftUI owns each part and how they connect. Define window, menu, focus, keyboard, saved state, restore, and multi-window behavior. Platform accessibility and resilience: Use the right accessibility APIs. Check VoiceOver and Full Keyboard Access. Support localization, contrast, and reduced motion when needed. Keep user state after a relaunch. Acceptance criteria: Check the behavior on supported macOS versions with a keyboard and VoiceOver. Window resizing, focus, state restore, and AppKit or SwiftUI integration work in the normal macOS way. Evidence and limits (evidence boundary): It is official for that source. Other platforms or teams may use the term in another way. Unknowns to confirm: Supported macOS versions, AppKit or SwiftUI structure, and window model. Also confirm sandbox and entitlement limits, save rules, and the accessibility goal.

Release checks: Check the supported macOS versions and AppKit or SwiftUI integration. Check standard focus and keyboard behavior. Also check VoiceOver, Full Keyboard Access, window resizing, and multi-window state. When needed, check restore, localization, and reduced motion.
