Note: When you build and run in Xcode, you might get mysterious build errors. You might see a prompt to allow access to the directory: Be sure to grant access so the app can read and write files. Click the folder icon to locate your begin folder.īuild and run, then open your browser to localhost:8080. Set Xcode’s working directory: Edit the Run▸My Mac scheme, and check the Run▸Options▸Working Directory checkbox. In Xcode, ensure you’ve selected the Run schema with My Mac as the target device. For this reason, your Model objects aren’t classes as usual, but simple Codable structs. Your project has no database support! Everything is driven by stored file content. It will take some for Xcode to download the dependencies but when it’s finished, Xcode will populate the schemes and show the dependencies in the project navigator.Īs with any Server-Side Swift project, your sample project uses MVC – but with a special twist! Take a look at the three files in your Models directory. Then open Terminal, navigate to the begin folder, and run this command: Use the Download Materials button at the top or bottom of this tutorial to download the starter project. While doing this, you’ll learn both synchronous and asynchronous file read and write techniques.įor a quick look at Vapor, see Getting Started with Server-Side Swift with Vapor Getting Started You’ll enable basic gameplay by reading and parsing stock templates from disk.įinally, since RetroLibs is best with your own stories, you’ll accept custom story templates and store them on the file system. You’ll find its starting page brimming with the vintage colors, fonts and styling of Web 1.0.įor this retro game, you’ll use the equally-classic method of reading and writing your story templates directly to and from the file system. It’s a nostalgic homage to the classic MadLibs text-based game. Your sample project for this file-handling tutorial is a Vapor app called RetroLibs. If you’ve worked with Server-Side Swift, you’ve likely used tools like Vapor’s Fluent or Kitura’s SwiftKuery to integrate databases and other structured data into your app.īut what if you need to interact directly with files and their contents? Do familiar iOS file management tools work as expected on a server and at web scale? You’ll find out in this tutorial. Part Two follows up by exploring best practices for serving up data between a Server-Side Swift app and its consumers. Part One focuses on the internal aspects of file handling: How to persist data to file, and how to access data stored within a server’s file system. In this two-part file-handling tutorial, you’ll take a close look at how Server-Side Swift handles and distributes files. The title parameter might become the email subject, the text, the message body, and the files, the attachments. Imagine if after running the code below, the user chose an email application as the target. Allowing all three members expands the flexibility of use cases. You can, for example, share text without a URL or vice versa. To keep the browser from throwing a TypeError, the object must contain at least one of the following properties: title, text, url or files. To share links and text, use the share() method, which is a promise-based method with a required properties object. safari 12.1, Supported 12.1 Source Sharing links and text #.
