Overview

SwiftLuhn

Swift CircleCI Version Carthage compatible License Platform

Warning! This repository is no longer maintained.

This is a port of the Luhn Algorithm, generally used for validating debit/credit card details, written in Swift.

SwiftLuhn's HEAD is written in Swift 4. If your project doesn't support Swift 4 yet, please use the 0.2.1 tag.

Objective-C port can be found at https://github.com/MaxKramer/ObjectiveLuhn.

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

Installation

SwiftLuhn is available through CocoaPods or Carthage (with or without using our pre-built binary).

To install it, simply add the following line to your Podfile:

pod "SwiftLuhn" # use '0.2.1' for Swift 3.X

Or alternatively the following line to your Cartfile:

github "MaxKramer/SwiftLuhn"

Usage

Validation

Call the class method which will throws an exception SwiftLuhn.CardError if the card is invalid.

let cardNumber = "378282246310005"
do {
    try SwiftLuhn.performLuhnAlgorithm(with: cardNumber)
    // process payment
}
catch {
    // invalid, alert user
}

Alternatively, you can use the String category:

let isValid = cardNumber.isValidCardNumber()

Card Types

You can also get the type of the card being used which will be one of:

Card Type
American Express
Visa
Mastercard
Discover
Diner's Club
JCB
do {
    let cardType = try SwiftLuhn.cardType(of: cardNumber)
}
catch {
	// card is invalid
}

Unit Tests

To run the unit test suite, please open the example project and hit CMD + U.

    Hi,

    On https://cocoapods.org the version available is 0.1 that is not compatible with Swift 3.

    Will you release the new version on cocoapods?

    Hello there,

    For some reason I have this error on pod install

    [!] Unable to satisfy the following requirements:

    • SwiftLuhn (~> 0.1.1) required by Podfile

    None of your spec sources contain a spec satisfying the dependency: SwiftLuhn (~> 0.1.1).

    and in the pod file I have this:

    What is happening? Broken tag?

  • Swift 3

    Swift 3

    Introducing Swift 3 support.

    Continuous integration is currently failing because CircleCI doesn't yet support Xcode 8 or Swift 3. I've opened a PR so that it can be manually tested by the community in the mean time. Unit tests are succeeding locally, so I don't have any further issues in terms of merging into master, however I'd appreciate some confirmations that this is indeed working as expected.

    Cheers, Max.

    Maestro and Rupay card type detection support

    Can we have the card type detection for maestro and rupay cards.

    looks like on line 119 (SwiftLuhn.swift)

    for i in CardType.amex.rawValue...CardType.jcb.rawValue {

    This iteration should go upto CardType.mir to support the card validation for maestro and rupay.
