Similar to this thread. How do we go about testing or triggering the UI for this new iOS/macOS 18 API?
Thanks!
Once you have implemented the API and enabled your extension in Settings > General > AutoFill & Passwords, you can tap twice or long press in any text field to bring up the callout bar (the UI for actions like Copy or Paste) and from there select AutoFill > Passwords to show your extension UI. Note that this API is for iOS only.
