![]() ![]() For most of these cases you just print the card title in this tutorial. onSceneEdit you get a callback and depending on what case it is you can react. (UserDefaultsHandler.encode(scenes: sceneIDs), forKey: ) SapURLSession: AppDelegate.sapURLSession) ServiceURL: URL(string: AuthenticationParams.redirectURL)!, NOTE: Make sure that the above mentioned files are added correctly to your project and are included in the build target.Ĭopy SceneAuthoringView(title: "Annotations", A static array would’ve done the job too but using the UserDefaults is just a bit smoother. Usually used for storing user preferences but in this tutorial a welcome alternative for using a true database. Now you can store, at runtime, information within the UserDefaults. ![]() The UserDefaults give you an interface to interact with the defaults system of the OS. This tutorial doesn’t use a true persistence layer for persisting information, here you will use the UserDefaults - Apple Developers. For this tutorial, because it is easier, you’re using an enum to store static information for establishing an OAuth connection challenge. There are many ways to work with static information in your iOS apps, one way would be to use a property list (plist), another is having an enum. Also the extension contains a method for attaching an OAuth Observer to the SAPURLSession in case you want to do deeper debugging on the network traffic. These are necessary to load, save and retrieve reality files stored within your app project.Īn extension written to create an OAuth session with the SAPURLSession. Here you get a quick overview of what the different utils are there for:Ī simple extension on FileManager - Apple Developers taking care of retrieving the documents directory, creating a directory in the documents directory and saving data to a directory. The util Swift files are provided in this tutorial:Įxtract the files into your project folder and drag them into the File Navigator of Xcode. This tutorial uses a number of utils used to do different type of tasks for your app. Make the ARScene conform to Identifiable and Codable: But it is an easy persistence for this tutorial. Of course this is not suitable for a production use case as the UserDefaults only exist in memory as long as the app is alive. In this tutorial you will use the ARScene model to store, the ID which is getting returned by the SAP Mobile Services API, in the UserDefaults. And there might be many cases where this is true for other entities. In that case your AR Scene entity as an 1-1 relationship to the Product entity. The user wants to place an augmented version of the product on a table. ![]() Imagine an ARScene might be displayed in case a user wants to see how a product from a product catalogue might look like. You should make sure to have an relationship between the Scene entity and some other entity it refers to. In a productive environment you want to have the AR Scene as an Entity in your Database holding the Scene information. Each time, the user creates a new AR Scene it gets an ID assign automatically after it has been published to SAP Mobile Services. ![]()
