As of iOS 11/macOS High Sierra, and only including ones in Foundation and CoreFoundation
Strings:
_NSCFString - a CFStringRef or CFMutableStringRef. This is the most common type of string object currently.
- May have 8 bit (ASCII) or 16 bit (UTF-16) backing store
_NSCFConstantString - a compile time constant CFStringRef, like you'd get with @"foo"
- May also be generated by dynamic string creation if matches a string in a pre-baked table of common strings called the StringROM
NSBigMutableString - an NSString backed by a CFStorage (https://github.com/opensource-apple/CF/blob/master/CFStorage.h) for faster handling of very large strings
NSCheapMutableString - a very limited NSMutableString that allows for zero-copy initialization. Used in NSFileManager for temporarily wrapping stack buffers.

Declare on your main init that all other init methods should call. It's a nice additional semantic warning. Works with Xcode 5.1 and above. Not tested with earlier variants, but should just be ignored. A reference to this macro shortly appeared in https://developer.apple.com/library/ios/releasenotes/ObjectiveC/ModernizationObjC/AdoptingModernObj…

Every time I hit something that annoys me in Xcode, I add the feature/UX improvement/change I'd like to the list.

Xcode Wish List:

Legacy Support

  • Additional optional downloads:
    • Older SDKs, eg, for building ancient projects.
    • Older compilers (for same).
  • Either ship gcc/llvm-gcc or don't. Don't ship clang and call it 'gcc', that just breaks anyone who actually needs GCC and finds your not-gcc in the PATH.

UX

Project/File Navigation
