![]() Open the Project Navigator on the left and click the project at the top. Tell Xcode where you'd like to store the project and click Create. Name the project Configurations, set Language to Swift, and make sure the checkboxes at the bottom are unchecked. Adding a Configurationįire up Xcode and create a new project by choosing the Single View App template from the iOS > Application section. There are several strategies to manage build configurations, but there are important differences you need to consider, especially in the context of security. In this episode, I show you how to safely manage data that is specific for a build configuration, such as API keys, credentials, and other sensitive data. This isn't new and it's a good practice to use build configurations to tailor a build to the specific needs of the environment it's going to be deployed to. Most projects define one or more additional build configurations for various reasons. On macOS, it uses a bar on the top of the view with titles, a lot like a segmented view.A brand new Xcode project defines two build configurations, Debug and Release. A TabBar on iOS has its bar at the bottom and an image and text as buttons. SwiftUI tries to adapt the UI declared in code to each platform. :] Optimizing the User Experience for Each Platform Build and run to see how SwiftUI adapts the UI on macOS.įantastic! You already have a simple app that runs on iOS and macOS! Take a moment to enjoy what you’ve accomplished so far. Favorite some gems and open the Favorites tab to see them listed there. Add FavoriteGems as the second view, with a Label with the title Favorites and the image of a heart.īuild and run on iOS.Next, add GemList as its first view, with a Label with the title “All” and the image of a list bullet.First, create a TabView as the root view.Open AppMain.swift inside the Shared AppMain: App Understanding the New App and Scene Protocol As such, having a group for each platform allows you to write specific code for each while still reusing a lot of code. You can create views that are reusable on each platform, but some behaviors are better suited for certain platforms. SwiftUI lets you share UI code between platforms, and it automatically adapts the UI depending on the device. Shared: code for both platforms, including models, business logic and reusable views. ![]() The starter project for this tutorial was built using this template. In it, you’ll find the new template for multiplatform apps. When creating a new project, Xcode 12 has a new section called Multiplatform. Notice how the groups are different than those in your usual iOS starter project. Considering the Project Structureīefore you start making any changes, take a look at the starter project. By tapping a row, you navigate to a details view located in DetailsView.swift. The main view of the app is in GemList.swift, showing a list of rows found in GemRow.swift that are fetched from a Core Data store. Open the different views inside the starter project to become familiar with the app. You’ll add this feature during this tutorial. The app has the code to fetch and save favorite gems from Core Data, but it can neither save nor list favorites yet. You can already scroll and tap gems to read facts about each one. Users can read interesting facts about them and save their favorites. RayGem is a simple multiplatform app that lists a collection of gems, which are precious or semiprecious stones. Open RayGem.xcodeproj inside the starter folder. So to follow this tutorial make sure you’re running the latest macOS version and Xcode 12.ĭownload the project materials by clicking the Download Materials button at the top or bottom of the tutorial. Also, this tutorial uses features from SwiftUI that are only available on iOS 14 and macOS 11 Big Sur. ![]() ![]() Although you don’t need a deep understanding of Core Data to follow along, here’s a great starting point if you want to learn more: Core Data with SwiftUI Tutorial: Getting Started. If you’re just getting started, check out SwiftUI: Getting Started. Note: This tutorial assumes you’re familiar with SwiftUI.
