Login Module

Welcome to the module. You are in the right place if you are looking to integrate a login form in your app. There two main configurations:

• List of providers for login. Apple is on by default, since Apple review process requires an Apple login option to always be present. Additionally, you can decide whether you wish to add Google and/or Facebook login.
• Request user notification access. Often in time, this is the best moment to request access to notification.

Usage

At any point of your app, use the following snippet to load the login view:

let vc = LoginControllerFactory.init(shouldRequestNotificationAccess: true, googleLogin: true, facebookLogin: true, shouldShowSkipButton: true).build()
vc.modalPresentationStyle = .overCurrentContext
self.present(vc, animated: true)

The UI will dynamically add the needed components according to your initial config:

• shouldRequestNotificationAccess
• googleLogin
• facebookLogin
• shouldShowSkipButton
