Since Xcode 13, code comparison default is no longer side by side.

There must be a way of doing this still.

I am struggling to find the option!

CodePudding user response：

Click on Code Review (the blue button on the screenshot), the one with one arrow to the left and the other one to the right (or in View Menu).

Then, on the second icon, select Side by Side Comparison instead of Inline Comparison (or in Editor Menu).

"Commits list" is at the bottom, on the bar with Enable Breakpoints, etc.
