Where is it most suitable? Good for large projects with a lot of abstract layers (horizontal separation) Good for middle-sized projects where you can separate features into different modules (vertical separation) Bad for small projects - will just make things too complicated

Slide 34

Slide 34 text

Pros Code separation and namespaces Due to that you design is better XCode will compile only what has changed You can go open source with your solution!

Slide 35

Slide 35 text

Cons Structure may become too complex for some apps CI gets harder (only if you have code in different repos) "Image not found” error. You have to master libraries Resources may end up not in main bundle Conflicts in *.pbxproj file. But you can use separate projects
