Summary:
Xcode has the option to disable auto-insertion of the closing curly bracket "Automatically insert closing brackets ("}")" and an option named "Automatically balance brackets in Objective-C method calls". The latter suggests that closing square brackets will not be inserted, however it doesn't work unless a second option is also unchecked. Plus it is not obvious that this same setting also disabled insertion of the closing parenthesis.

Steps to Reproduce:
- Open Xcode, open an Objective-C .m file
- Open Xcode Preferences > Text Editing and uncheck "Automatically balance brackets in Objective-C method calls" and check "Enable type-over completions" (whatever this means)
- Write an arbitrary method in the .m file
- Start typing: "NSString *str = [[NSString alloc" OR "if (flag"

Expected Results:
- No auto-insertion happens

Actual Results:
- Two closing square brackets (1) or a closing parenthesis (2) are automatically inserted

Regression:
When unchecking the other option, "Enable type-over completions", of which I have no idea what it does, the closing brackets and parenthesis do NOT get inserted, as was desired. It's not obvious why this option is dependent on the other type-over option and it's also not obvious that it also applies to parentheses.
