项目内的Xcode项目

Question

I'm taking over some project of a colleague that is on holidays now.

Other projects have gone fine, but in this particular one, I have found a project inside a project, like using a framework I guess.

So what is the name of this technique?

How to insert and interact with it? just import?

Answer 1

They are called cross project references. From the link below:

Cross-project references are a convenient way to create relationships between two separate Xcode projects.

One method of creating shared frameworks is using sub-projects. You can also do it with single projects. More here:

Answer 2

cross-project references aka project in project aka sub-project aka nested projects . This approach uses Explicit dependency ^[About]

If you already have separate Xcode projects for your framework and application, you can take advantage of Xcode's cross-project references to embed the framework in your application. Cross-project references are a convenient way to create relationships between two separate Xcode projects.

To define explicit dependencies between targets in separate project files, project files should be nested . This means that a target can set explicit dependencies of any other target within the same project file, or any nested child project file.

This approach allows you to automatically build a binary with the rest of your app, using your current build configuration (eg, debug, release, etc.) and avoid pre-building several versions of the binary separately (where each version was built for a specific environment/configuration) using Explicit dependency ^{[About] [How to setup]}
