Add a local Swift Package to your project with Swift PM

In SwiftPM, you may want to add a local Swift Package to your project. For example, if you want to work with projects and dependent packages in a single repository (mono repo).

According to Swift PM Lead Developer's Answer, drag a package into your project It's OK if you drop and drop it, but at least it didn't work in my environment (although this answer is "the way it should be", so I think it will be resolved in a future update).

This article summarizes the current workaround in my environment (2020/11/15).

environment

• MacBook Pro (Retina, 15-inch, Mid 2015)
• macOS Catalina 10.15.7
• Xcode 12.0

procedure

1. Make the Swift Package you want to add into your local git repository. This git repository will be deleted later, so it doesn't matter how you do it (git init; git add.; git commit -m "init" )
2. Place the Swift Package directory you want to add somewhere in your project folder.
3. Drag and drop the Swift Package directory you want to add into your Xcode project.
4. From the Xcode menu, go to [File]-[Swift Package]-[Add Package Dependency] and specify the path of the relevant Swift Package. It is in the form of "file: // + full path". For example, file: /// Users / n / d / expProject / expdat / swiftPackage.
5. Correct the path. Open .pbxproj as a text file and search for file: // Then find the path specified in 4. and replace it with a relative path. For example, ./expdat/swiftPackage.
6. Remove the .git directory from the Swift Package directory.

At the time of 4., the addition to the project has already been completed, but it can only be handled locally, and it will not be possible to push with Git or the like. In order to solve it, we are following the steps of 5. and 6..

that's all.
