Smile-Lock is an open source iOS Swift based interface component from Rain for creating password entry views similar to the iOS provided lock screen complete with animations.
Smile-Lock can be implemented with interface builder, colors can be customized, and the number of dots displayed representing the number of digits within the password.
A delegate callback is used for when the user enters the right password.
Here’s an image from the readme showing Smile-Lock in action:
