Preparation

Configure in Slack API Documentation (opens new window) and Authing Console (opens new window), please refer to [Slack Access Preparation](.. /../../guides/connections/social/slack-mobile/README.md).


Integrate Slack login

Step 1: Add Slack dependency

  1. Enter: https://github.com/Authing/authing-binary in the swift package search bar.

  2. Select Authing-binary (opens new window).

Authing-binary (opens new window) depends on Guard-iOS SDK (opens new window).

  1. Select Up to Next Major Version 1.0.0 for the dependency rule.

  2. Check Slack after Add Package.

Slack depends on Guard-iOS 1.4.5 (opens new window) later.


Step 2: Initialize Slack login

import Guard
import Slack

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
     Authing.start(<#AUTHING_APP_ID#>)
     // appId: Slack ClientID
     // redirectURI: Slack authorization callback page
     // scope: empty by default
     Slack.register(appId: <#your_slack_appid#>, redirectURI: <#your_slack_redirecturi#>, scope: <#your_slack_scope#>)
}

Step 3: Initiate Slack login authorization

Slack authorized login

func login(viewController: UIViewController, completion: @escaping Authing.AuthCompletion) -> Void

parameter

  • viewController UIViewController hosting the view

example

Slack.login(viewController: <#ViewController#>) { code, message, userInfo in
     if (code == 200) {
         // login successful
         // userInfo
     }
}

If the developer integrates Slack login by himself, after getting the AuthorizationCode, he can call the following API in exchange for the Authing user information:

Login via Slack Authorization Code

func loginBySlack(_ code: String, completion: @escaping(Int, String?, UserInfo?) -> Void)

parameter

code Slack authorization code

example

AuthClient().loginBySlack(authCode) { code, message, userInfo in
     if (code == 200) {
         // userInfo: user information
     }
}
