EnterpriseAppUpdater

Enterprise App Updater loads app's manifest file, checks for a new version, provides an alert with patch notes and starts the update.

Setup

Swift Package Manager (preferred)

Open your application project in Xcode 11 or later, go to menu File -> Swift Packages -> Add Package Dependency... and paste the package repository URL https://github.com/DnV1eX/EnterpriseAppUpdater.git.

CocoaPods (deprecated)

Add the pod to your Podfile:

pod 'EnterpriseAppUpdater', '~> 1.1'

Copy File (not recommended)

Alternatively, you can manually copy EnterpriseAppUpdater.swift into your project.

Prepare Application Manifest

1. Generate manifest.plist during enterprise app distribution in Xcode Organizer;
2. Make sure software-package asset contains direct https link to the app's .ipa;
3. Optionally add release notes to subtitle metadata to display in the update alert (use \n for line break);
4. Upload the manifest and get a direct https link you will use to initialize EnterpriseAppUpdater.

Manifest URL must remain the same when the update is released, you only edit .plist content such as app url, bundle-version and optional subtitle.

Usage Example

import EnterpriseAppUpdater
typealias Updater = EnterpriseAppUpdater

let updater = Updater(manifest: url) // Initialize EnterpriseAppUpdater with manifest.plist URL.
updater.loadManifest { result in
    switch result {
    case .success(let manifest):
        switch updater.check(manifest: manifest) {
        case .success(let item):
            let alert = updater.alert(for: item, onStart: { _ in
                print(Updater.Message.started, item.metadata.version)
                updater.start { error in
                    print(Updater.Message.error, error)
                }
            }, onPostpone: { _ in
                print(Updater.Message.postponed, item.metadata.version)
            })
            self.present(alert, animated: true) // Use UIApplication.shared.windows.first?.rootViewController? if self is not UIViewController.
        case .failure(let error):
            switch error {
            case .noAppUpdateNeeded:
                print(Updater.Message.upToDate, error)
            default:
                print(Updater.Message.error, error)
            }
        }
    case .failure(let error):
        print(Updater.Message.error, error)
    }
}

It's up to you whether to load manifest and check for update on the app launch, at time intervals, or by user request.
