Comparison and range operators
The Swift branching features: if and switch
Loops: for, while, repeat…while
You now have the skills needed to develop robust applications using Swift's powerful and expressive language syntax. In the next lesson, you'll learn the skills to develop functions and classes to organize your code. You will also explore and use error handling to efficiently handle unexpected errors in your programs.
