Passcode Screen

A Swift implementation of passcode lock for iOS with TouchID and FaceID authentication.

Getting Started

Passcode Screen requires Swift 5.0 and Xcode 11.

Library has main 3 features as follow:

• Create PIN
• Verify PIN
  • Verify PIN with Digits
  • Biometric Verification (Touch ID / Face ID)
• Change PIN

Manual Installing

A simple manual installation with drag and drop directory option will enabled your app with Passcode Lock.

Copy PasscodeVC directory to your project

Usage

Wherever you want to open Passcode Screen. Just copy past below code to your ViewController.

1. Show Passcode Screen over rootviewcontroller :

    if let vc = PasscodeViewController.instance(with: .VERIFY) {
        vc.show { (passcode, newPasscode, mode) in
            print(passcode, newPasscode, mode)
            if passcode.lowercased() == "biometric" {
                vc.dismiss(animated: true, completion: nil)
            }  else {
                vc.startProgressing()
                DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 3.0) {
                vc.stopProgress()
            }
        }
    }    

2. Show Passcode Screen over current viewController :

    if let vc = PasscodeViewController.instance(with: .VERIFY) {
        vc.show(in: self) { (passcode, newPasscode, mode) in
            print(passcode, newPasscode, mode)
            if passcode.lowercased() == "biometric" {
                vc.dismiss(animated: true, completion: nil)
            }  else {
                vc.startProgressing()
                DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 3.0) {
                vc.stopProgress()
            }
        }
    }    

3. Start Animating Dots :

vc.startProgressing()

4. Stop Animating Dots :

vc.stopProgress()

Theming

In PasscodeConfig class you can modify following options for changing the theme colors and icons

var logoImg: UIImage?
var backspaceImg: UIImage? = UIImage(named: "btn_backspace")
var touchIdImg: UIImage? = UIImage(named: "btn_biometric")
var faceIdImg: UIImage? = UIImage(named: "btn_faceid")
var backgroundColor: UIColor = .darkGray
var msgColor: UIColor = .white
var keyTintColor: UIColor = .white
var keyHighlitedTintColor: UIColor = .lightGray
var keyHighlitedBackgroundColor: UIColor = UIColor.white.withAlphaComponent(0.2)
var digitColor: UIColor = .white

Customization

You can easily customize the following options for the library

• Set no. of digits
  • PasscodeViewController.config.noOfDigits = 6
• Set enable/disable random key numbers
  • PasscodeViewController.config.isRandomKeyEnabled = randomKeySwitch.isOn
• Change label messages
  • PasscodeViewController.config.EnterCurrentPasscodeMessage = "Enter PIN"
  • PasscodeViewController.config.EnterNewPasscodeMessage = "Please enter a new PIN"
  • PasscodeViewController.config.ReEnterPasscodeMessage = "Confirm your PIN"
  • PasscodeViewController.config.PasscodeNotMatchMessage = "Confirm PIN doesn't match"
