A real world usage for git subtrees.
View example-subtree-usage.md

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add git@github.com:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

Table showing the major translations from Objective-C to Swift syntax
View Obectivej-C to Swift Syntax Translation.md

Conversion Process from Objective-C syntax to Swift The most important first step is to run Apple's "Convert to Modern Objective-C Syntax" refactoring, so that you're using array/dictionary literals and bracket-accesses; these will then be usable in Swift. Note also that I'm a beginner in Swift, so my apologies for any mistakes or incompleteness here.

When you see this pattern Replace with this
Module
@interface *newType* : *superType* <*protocol1*, *protocol2*> class *newType* : *superType*, *protocol1*, *protocol2*
@implementation OR @synthesize OR @end Delete
