I can answer the first question. Adding a folder to a project is similar to adding individual files. Choose File> Add Files To Xcode. When you add the file folder to the project, you should see something like the following screenshot:

Create groups if you need to access files in Xcode, for example, add a folder from source code files. Create links to folders if you donβt need to access files in Xcode, for example, add a folder of audio files.
You can also add folders to the project navigator by selecting a file or folder in the project navigator, right-clicking and selecting New Group.
