Question 1

How to add Touch ID authentication to my Swift app using SimpleTouch?

Accepted Answer

Import the SimpleTouch framework, check for Touch ID support with SimpleTouch.isTouchIDEnabled, and present authentication using SimpleTouch.presentTouchID with customizable prompts, as detailed in the README examples for a quick setup.

Question 2

Does SimpleTouch work with Face ID or only Touch ID?

Accepted Answer

SimpleTouch is specifically designed for Touch ID only and does not support Face ID. For projects needing both biometric methods, you should use Apple's LocalAuthentication framework directly or a more comprehensive library.

Question 3

SimpleTouch vs LocalAuthentication: which should I use for iOS biometrics?

Accepted Answer

SimpleTouch provides a simpler, type-safe wrapper focused solely on Touch ID, reducing boilerplate. However, LocalAuthentication is Apple's official framework that supports both Touch ID and Face ID, offering better future-proofing and integration with iOS updates.

Question 4

How to handle errors when Touch ID fails with SimpleTouch?

Accepted Answer

Interrogate the error enum in the response case to identify specific failures, such as user cancellation or hardware issues, using the comprehensive error handling features mentioned in the README for debugging.

Question 5

Is SimpleTouch still maintained and compatible with latest iOS versions?

Accepted Answer

The README does not indicate recent updates, and its focus on Touch ID only suggests it may not be actively maintained for newer iOS features. Check the GitHub repository for current activity or consider alternatives if up-to-date support is critical.

Question 6

Can I use SimpleTouch in a SwiftUI project?

Accepted Answer

Yes, but the README doesn't provide specific SwiftUI guidance. Since SimpleTouch uses standard UIKit APIs, you can integrate it via interoperability, but you may need additional bridging or wrapper code for a seamless SwiftUI experience.
