Implementing Force Update Feature using Firebase Remote Config in iOS

AppDelegate.swift

override func applicationDidBecomeActive(_ application: UIApplication) {
        print("AppDelegate : application applicationDidBecomeActive()")
        
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
        super.applicationDidBecomeActive(application)
        
        //setup remote config
        setupRemoteConfig()
        
        ForceUpdateChecker(listener: self).check()
}
