A better way is to print the value of tasksDocURL before the TaskStore loads its prioritized tasks. After this, check the appвЂ™s documents directory youвЂ™ll see that it created a new rwtl file.ДЇinding the data folder can be a hassle if you navigate folder by folder. Now change the first line so that it uses your new file extension:Д«uild and run, but notice that nothing changed.

Constructing the URL for reading and writing the list data with the file extension and saving it to a file named PrioritizedTasks.

Storing the file extension as a static variable.

RelativeTo: FileManager.documentsDirectoryURL) To see this at work, open TaskStore.swift and look at the two lines below the shared instance declaration: You can then write the data to a file on the userвЂ™s device. Since Task conforms to Codable, itвЂ™s easy to use SwiftвЂ™s built-in PropertyListEncoder to encode a list of tasks into a property list Data blob.

The sample project already includes code to save tasks to a file. The first step in this process is to use the custom file type in the app. RWTL, short for Ray Wenderlich Tasks List. For this tutorial, your custom file type will be. To achieve this, youвЂ™re going to create a new file extension and register the new file type as something your application can import. At the same time, it would be convenient for your users to be able to identify file types that are compatible with your app when they see them. Your app should be able to identify files it can import. But before you can kick off the import, youвЂ™ll create a custom file type to facilitate the process. Instead, why not import an existing list of tasks? YouвЂ™ll do just that. You could add items one by one, but that would be tedious. So, right now you donвЂ™t have any data to export. Whenever you change something in the list, like add an item or mark one as completed, the store saves its current contents into a plist file in the documents directory.Д«uild and run your project, and youвЂ™ll see no tasks under the four priority levels.

TaskStore.swift is the data store of the app.

It lists all the items in the data store with their priority.

ContentView.swift is the view you see when you fist launch the app.

YouвЂ™ll enhance this project by modifying the following two files: The project has everything you need to do basic exporting and importing of data. It has basic functions such as adding, editing and deleting tasks, as well as marking them complete.Д«efore you dive into the code, you should know a little about the project structure. The project youвЂ™ll build is an app for saving and tracking tasks you donвЂ™t want to forget. If these are new topics for you, check out our SwiftUI: Getting Started and Combine: Getting Started tutorials before moving on.

The app is also built using SwiftUI and Combine. Note: The sample project is from the Video Course Saving Data in iOS by Felipe Laso Marsetti.
