iOS App Update Notification

How to alert user of new update of iOS app

Don't worry there is no code required. I've recently updated my app and I was wondering the same thing. It should do it automatically once the new version is on the store. A small red icon will appear in the top right of the App Store app icon. ;)

Is it possible to send update notification to app users iOS

Code for App Version Comparision is:

 func checkAppUpdateAvailability(onSuccess: @escaping (Bool) -> Void, onError: @escaping (Bool) -> Void) {
        guard let info = Bundle.main.infoDictionary,
              let curentVersion = info["CFBundleShortVersionString"] as? String,
              let url = URL(string: "http://itunes.apple.com/lookup?bundleId=com.facebook.app") else {
            return onError(true)
        }
        do {
            let data = try Data(contentsOf: url)
            guard let json = try JSONSerialization.jsonObject(with: data, options: [.allowFragments]) as? [String: Any] else {
               return onError(true)
            }
            if let result = (json["results"] as? [Any])?.first as? [String: Any], let appStoreVersion = result["version"] as? String {
                print("version in app store", appStoreVersion," current Version ",curentVersion);
                let versionCompare = curentVersion.compare(appStoreVersion, options: .numeric)
                if versionCompare == .orderedSame {
                    onSuccess(false)
                } else if versionCompare == .orderedAscending {
                    onSuccess(true)
                    // 2.0.0 to 3.0.0 is ascending order, so ask user to update
                }
            }
        } catch {
            onError(true)
        }
    }

Now you can check App Update.

checkAppUpdateAvailability { (status) in
            //When status == true show popup.
        } onError: { (status) in
            // Handle error
        }

Iphone app update notification not getting from app store to My iphone

Harpy checks a user's currently installed version of your iOS app
against the version that is currently available in the App Store. If a
new version is available, an alert can be presented to the user
informing them of the newer version, and giving them the option to
update the application.
