Objective-C Coding Convention and Best Practices

Most of these guidelines are to match Apple's documentation and community-accepted best practices. Some are derived some personal preference. This document aims to set a standard way of doing things so everyone can do things the same way. If there is something you are not particularly fond of, it is encouraged to do it anyway to be consistent with everyone else.

This document is mainly targeted toward iOS development, but definitely applies to Mac as well.

Operators

NSString *foo = @"bar";

mayoff

The attached lldb command pblock command lets you peek inside an Objective-C block. It tries to tell you where to find the source code for the block, and the values captured by the block when it was created.

Consider this example program:

#import <Foundation/Foundation.h>

@interface Foo: NSObject
@end

@implementation Foo

Catfish-Man

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.

    /**
     Draws the super-elliptic analog of a rounded rect. Unlike the regular rounded rect, the rounded corners
     are the quadrants of a superellipse (i.e., parabolic segments), _not_ circular arcs.
     If `rect` is a square and `cornerRadius` is equal to half the length or more, and actual superellipse is
     drawn (no straight sections along its boundary) just like doing the same with a rounded rect results in a
     circle being drawn.
