LLVM 4.0 Compiler
Xcode now includes the Apple LLVM Compiler version 4.0, including the following new Objective-C language features:
- Default @synthesize: automatically synthesizes an @property when unimplemented
- Objective-C literals: create literals for NSArray, NSDictionary, and NSNumber, just the same as the literals for NSString
- Objective-C container subscripting: use ’[]’ syntax to access containers such as NSArray and NSDictionary
