Even with 1 storyboard, as long as you don&#x27;t commit completely unrelated changes, you can still have 9 people working on it just as easily as you can if you split it up into one storyboard per view controller. All this requires is that people actually look at the diff they&#x27;re committing and omit changes to unrelated view controllers (most graphical commit tools will let you pick the lines to commit).
