i want to add lock app feature, like iOS lock.

Can I add a lock screen on my iOS app?

my requirement is : whenever a user opens the app, he/she need to unlock the app first then only he/she can operate the app.


There so system affordance for this, but plenty of apps do it the hard way:

  • Present a UI that sits on top of the app’s real content, which prevents the user from seeing or interacting with that content.

  • Extend that UI to support unlocking.

You included the Face ID tag on your post, so I presume you want to support unlocking with Face ID. If so, check out the Local Authentication framework.

Share and Enjoy
