Sign In with Apple - Swift


In this section you learn how to get started with Sign In with Apple using our Swift template and get ready to use Back4App in a few easy steps.


To complete this quickstart, you need:

  • Xcode 11
  • Set up Sign In with Apple in your Apple Developer account.

Step 1 - Get the template

Clone or download the template at
Back4App’s GitHub repository, open the Swift foder.

Step 2 - Open the project template

  1. Open Xcode.
  2. Click on File->Open.
  3. Navigate to the project folder and double click on app.xcworkspace.
  4. Wait for Xcode to open the project.

Step 3 - Setup app’s credentials

Update your App Delegate’s Parse Client Configuration values to set up the app’s credentials. Parse iOS SDK uses these settings to connect to the Back4App servers.

  2. Go to your App Dashboard at Back4App website.
  3. Navigate to app’s settings: Click on Features > Core Settings block > Server.
  4. Return to your AppDelegate.swift file and paste your applicationId and clientKey.
