O365 - IOS - Swift - Unified API - Display the list of users from the tenant

After my recent switch over to Mac as my main laptop for O365 / SharePoint development, Finally I got an IOS native app running using the O365 IOS SDK and Swift. Nearly after 15 years of development using Microsoft Technologies and Tools, the mobile app development using XCode and Swift rekindles my memory of learning the Object Oriented Programming using C and C++.

Step 1 : Register the app on the Azure AD 

Step 2: Create a Single View application in the XCode

Step 3 : Setup the Pod file to install the following

• pod 'ADALiOS', '~> 1.2.2'

• run "pod install" on the terminal or "pod update" if you want to upgrade to the latest. (The below screen shot shows the output of the update - because I installed the old version first and updated to the latest).
