Editing

Unlike traditional Xcode projects or Swift Packages, where changes are done through Xcode's UI, Tuist-managed projects are defined in Swift code contained in manifest files. If you're familiar with Swift Packages and the Package.swift file, the approach is very similar.

You could edit these files using any text editor, but we recommend to use Tuist-provided workflow for that, tuist edit. The workflow creates an Xcode project that contains all manifest files and allows you to edit and compile them. Thanks to using Xcode, you get all the benefits of code completion, syntax highlighting, and error checking.

Edit the project

To edit your project, you can run the following command in a Tuist project directory or a sub-directory:

tuist edit

The command creates an Xcode project in a global directory and opens it in Xcode. The project includes a Manifests directory that you can build to ensure all your manifests are valid.

GLOB-RESOLVED MANIFESTS

tuist edit resolves the manifests to be included by using the glob **/{Manifest}.swift from the project's root directory (the one containing the /Tuist directory). Make sure the /Tuist directory contains a valid Config.swift

Edit and generate workflow

As you might have noticed, the editing can't be done from the generated Xcode project. That's by design to prevent the generated project from having a dependency on Tuist, ensuring you can move from Tuist in the future with little effort.

When iterating on a project, we recommend running tuist edit from a terminal session to get an Xcode project to edit the project, and use another terminal session to run tuist generate.
