Summary
In this chapter, we looked at some of the different documentation that Apple and the Swift community offer. This documentation can be essential as you are learning Swift and also for reference once you have mastered the language itself. We also looked at how we can build and install Swift and its full toolchain. While using the latest build of Swift is not recommended for production systems, I usually keep a virtual machine or my desktop setup with a recent build. This enables me to use the latest features of the language and also run my code against it to make sure I am not introducing changes that are not compatible with future versions of the language.
In the next chapter, we will start to get into the language itself and we will see how to use variables and constants in Swift. We will also look at the various data types and how to use operators in Swift.
