Enable Xcode-> Settings-> TextEditing-> Editing-> Automatically balance brackets in ObjectiveC method calls
I am using Xcode Version 5.0.2 (5A3005). Below both of them worked great for me. It automatically created a left bracket when I closed the correct one.
[self someFunc:1 Flag:YES|YES|YES]; [self someFunc:YES|YES|YES]; - (void)someFunc:(int)x Flag:(BOOL)yes { } - (void)someFunc:(BOOL)yes { }
Here are my Xcode settings
