OVERVIEW

PasscodeKit is a lightweight and easy-to-use, in-app Passcode implementation for iOS. It includes a custom numeric keypad, optional haptic feedback, and Face ID / Touch ID support.

INSTALLATION

Swift Package Manager

Swift Package Manager is a tool for managing Swift code distribution.

To add PasscodeKit as a dependency to your project, follow these steps:

1. Open your Swift project in Xcode.
2. Navigate to File -> Add Package Dependencies....
3. Paste https://github.com/relatedcode/PasscodeKit.git into the search bar.
4. Choose the version you want to use and click Add Package.

Manually

If you prefer not to use the dependency manager above, you can integrate PasscodeKit into your project manually. Simply copy all the *.swift files from the PasscodeKit/Sources folder into your Xcode project.

REQUIREMENTS

• iOS 13.0+

QUICKSTART

To activate the PasscodeKit in your codebase, you need to start it right after the app is launched. The best practice to do it in the AppDelegate didFinishLaunchingWithOptions method.

PasscodeKit.start()

The following PasscodeKitDelegate methods can be used to take actions related to the PasscodeKit user activity.

func passcodeCheckedButDisabled()

func passcodeEnteredSuccessfully()

func passcodeMaximumFailedAttempts()

To enable, disable the passcode functionality, or to change the saved passcode you can use the following methods.

PasscodeKit.createPasscode(self)

PasscodeKit.changePasscode(self)

PasscodeKit.removePasscode(self)

CUSTOMIZATION

The following settings are available for customizing the passcode-related user experience.

PasscodeKit.passcodeLength = 4

PasscodeKit.allowedFailedAttempts = 3

PasscodeKit.hapticFeedback = true

PasscodeKit.textColor = .darkText
PasscodeKit.backgroundColor = .lightGray

PasscodeKit.failedTextColor = .white
PasscodeKit.failedBackgroundColor = .systemRed

PasscodeKit.titleEnterPasscode = "Enter Passcode"
PasscodeKit.titleCreatePasscode = "Create Passcode"
PasscodeKit.titleChangePasscode = "Change Passcode"
PasscodeKit.titleRemovePasscode = "Remove Passcode"

PasscodeKit.textEnterPasscode = "Enter your passcode"
PasscodeKit.textVerifyPasscode = "Verify your passcode"
PasscodeKit.textEnterOldPasscode = "Enter your old passcode"
PasscodeKit.textEnterNewPasscode = "Enter your new passcode"
PasscodeKit.textVerifyNewPasscode = "Verify your new passcode"
PasscodeKit.textFailedPasscode = "%d Failed Passcode Attempts"
PasscodeKit.textPasscodeMismatch = "Passcodes did not match. Try again."
PasscodeKit.textTouchIDAccessReason = "Please use Face ID or Touch ID to unlock the app"

CONFIGURATION
