shared development in swift

This is my first answer. I'm sorry if it's far from what I asked.

In general, what do you do when you share and develop?

There are two types of development: development using storyboard and development without use (coding UI).
They can be used differently depending on the size of the project and the complexity of the UI.
Also, I think it is common for development using storyboard to divide Storyboard files and avoid enlargement.

As a prerequisite, I think that the members need to match the configuration using AutoLayout and the version of StoryBoard.

Basically, even if multiple workers use the same StoryBoard, you can automatically merge by pulling from the XCode.

If you conflict, the contents of the StoryBoard file are XML, so you may have to modify it directly.If the layout is worn out, the layout will collapse and the situation will be restored to COMMIT at some point, but the following measures can be taken to avoid this situation.(It's only a part)

• Reduce the granularity of COMMIT
  Reduce the number of changes to the StoryBoard by a single COMMIT and ensure that there are no problems as appropriate

• Divide StoryBoard
  ex)
  Set the layout between A and B to C to StoryBoard1
  D-E-F layout as StoryBoard 2

  If you switch between StoryBoard, you will need to read the StoryBoard in code and pass it to the ViewController.
