How do you improve collaboration when working with Swift?

On How do you improve collaboration when working with Swift?, the part about collaboration and swift stands out to me.

It also gives you a cleaner baseline if you want to compare tools or settings later.
 
A useful way to look at How do you improve collaboration when working with Swift? is to focus first on collaboration and swift. That tends to make the trade-offs easier to compare. It is usually easier to troubleshoot when each change is tested on its own.
