Swift documentation

Apple and the Swift community, as a whole, have released a number of resources to help developers program in Swift. Apple's official documentation, which can be found at https://developer.apple.com/documentation/, includes API documentation for Swift as well as all of Apple's frameworks. Only a small portion of Apple's frameworks are open source and work across all platforms; however if you are looking to get started on one of Apple's frameworks this is definitely the place to start. However it can be hard to find documentation on specific Swift APIs.

To quickly find documentation on Swift's API, my favorite site is https://swiftdoc.org. This site is incredibly easy to navigate and has autogenerated documentation for all types, protocols, operators, and global functions that make up the Swift language. I have noticed that this site does not always stay up to date; however, it is a great reference for any Swift developer. The code that generates this site is open source as well and can be found on GitHub here: https://github.com/SwiftDocOrg/swift-doc. The GitHub page gives directions on how you can generate your own offline documentation.

The final site that I am going to mention here is one that I recently discovered on one of my favorite Swift sites. It is the Swift knowledge base on the Hacking with Swift site located here: https://www.hackingwithswift.com/example-code/. Once you learn Swift and need to know how to do something like parsing JSON, extracting a PDF, or any other specific function, there is a good chance you can find what you need here.

Now that we know where to look for documentation on Swift, let's see the different ways that we can install Swift.
