Increase the length of Xcode's "recent project" list?

I switch in Xcode between working on a lot of different projects frequently (some I'm actively working on, some are old projects where I'm looking up code I want to re-use or quote in SO answers :)), so that part of my "working set" of projects invariably ends up falling off the recent project list. I do use finder tabs for the full working set of current project folders, but I really like the fast switching avail开发者_如何学Cable using the recent projects list.

Is there a way to increase the length of this list so that I can see more recently opened projects?

On a terminal window, for XCode 7 and above type the following command: (from Matteo Gaggiano):

defaults write com.apple.dt.Xcode NSRecentDocumentsLimit X

where X is the max number of projects in list.

For XCode version below 7, the following worked.

defaults write com.apple.Xcode NSRecentDocumentsLimit X

You could change the length of the list with the number of recent items in System Preferences -> General (Appearence on older macOS versions) as well. However that will change it for all apps.

You need to restart your machine for the change to kick in.
