SimpleAuth is designed to do the hard work of social account login on iOS. It has a small set of public APIs backed by a set of “providers” that implement the functionality needed to communicate with various social services.

SimpleAuth currently has the following providers:


Install SimpleAuth with CocoaPods. For example, to use Facebook and Twitter authentication, add

pod 'SimpleAuth/Facebook'
pod 'SimpleAuth/Twitter'

to your Podfile.


Configuring and using SimpleAuth is easy:

// Somewhere in your app boot process
SimpleAuth.configuration()["twitter"] = [
    "consumer_key": "KEY",
    "consumer_secret": "SECRET"

// Authorize
func loginWithTwitter() {
    SimpleAuth.authorize("twitter", completion: { responseObject, error in
        println("Twitter login response: \(responseObject)")

Implementing a Provider

The API for creating providers is pretty simple. Be sure to look at SimpleAuthProvider and SimpleAuthWebLoginViewController. These classes will help you simplify your authentiction process. Providers should be stored in Pod/Providers/ and have an appropriately named folder and sub spec. All providers are automatically registered with the framework. There are a handful of methods you’ll need to implement:

Let SimpleAuth know what type of provider you are registering:

+ (NSString *)type {
    return @"facebook";

Optionally, you may return a set of default options for all authorization options to use:

+ (NSDictionary *)defaultOptions {
    return @{
        @"permissions" : @[ @"email" ]

Finally, provide a method for handling authorization:

- (void)authorizeWithCompletion:(SimpleAuthRequestHandler)completion {
	// Use values in self.options to customize behavior
	// Perform authentication
	// Call the completion

The rest is up to you! I welcome contributions to SimpleAuth, both improvements to the library itself and new providers.
