Leave the checkbox Create Git repository on My Mac unchecked. You can leave Use Core Data and Include UI Tests unchecked.Ĭlick Next and tell Xcode where you'd like to save the files for the project. At the bottom, check Include Unit Tests to tell Xcode to create a unit test target. Set Language to Swift and devices to Universal. Open Xcode and create a new project by choosing the Single View Application template from the iOS > Application section.

The first step is simple, setting up the project and updating the project structure. We also take a close look at how we can improve the default structure of the project.

We start this series by creating and configuring the project in Xcode.

You also learn some best practices that may become invaluable in your toolbox. If you have a basic understanding of iOS and Swift development, then this series teaches you how the various pieces fit together.

Putting Your Project Under Source ControlĮven though this list may seem daunting, a typical iOS project requires you to have these skills.

Creating User Interfaces With Storyboards and Auto Layout.

Creating an Application With Xcode and Swift 3.

Along the way, you learn several skills that are essential for iOS development, including:

You can add your own folders if you want.Sign in with GitHub to download the source files of this episode for free. Xcode treats any files we add to the Preview Content folder as development assets. We are not limited to this one preview asset catalog. Xcode will not include any assets you add to the preview asset catalog in your release builds. Xcode treats this asset catalog differently from your apps main asset catalog. You may have already noticed that if you create a new SwiftUI project Xcode creates a Preview Content folder for you and adds an empty asset catalog: The next step is to exclude this data from your release builds by letting Xcode know they are development assets. This might be in a standalone type or as an extension on the model (or view model):Įxtension Country Ĭollecting the preview data into one place is a good first step. Development AssetsĪn approach I’ve seen from a few iOS developers and Apple engineers during WWDC videos is to create the preview data alongside the model. Without doing anything special I’m already copying and pasting variations of the same preview data multiple times.

For example, how does my cell layout work when the country name wraps over multiple lines: I’m also likely to want variations on the sample data for different edge cases. I created the rows in my list with country cell views which also need some of the same sample data: I also want sample data when displaying countries in a list: That approach makes it easier to play with the data but it soon gets out of hand. For example, here’s my preview of a view that displays a Country with some sample model data created in the preview provider: At first I tended to create the sample data for the preview along with the preview. The tight integration Xcode provides between the declaration of a SwiftUI view and its preview gives you fast feedback as you make changes.

This speeds up development but where do you keep your preview data? If you’re not careful your view code can become cluttered with sample data. One of the great features of SwiftUI is the Xcode support for previewing views without launching the simulator.
