Swift Programming Language

Read the sections described below in the The Swift Programming Language: Language Guide. The goal of this reading is not to learn every aspect of Swift, but rather to learn the basics, become familiar with the documentation and where to find details of specific features, and to see lots of examples. To better emphasize important concepts, the sections in the reading have been annotated with three colors:

• Very Important : Read these carefully. They may more subtle than other parts but are important.
• Important : Read these carefully as well, but they should be easier to understand.
• Optional : Not required for now.
