xCode 4 关闭一些特性

This is a (somewhat) hidden preference which allows you to define the number of concurrent compile tasks:

defaults write com.apple.dt.XcodeIDEBuildOperationMaxNumberOfConcurrentCompileTasks4

To Disable Indexing in the IDE

This one disables code sense indexing, which can save a lot of resources in large projects:

defaults write com.apple.dt.XCodeIDEIndexDisable1

to reenable:

defaults delete com.apple.dt.XCodeIDEIndexDisable

Note that you should quit Xcode, set the preference values as desired, changes take effect when you restart Xcode.

 

 

defaults delete com.apple.dt.XCode IDEIndexEnable
