This article is part of a series on learning Swift by writing code to The Swift Programming Language book from Apple. This is the second article in Section 2 (here is Section 1)
Read each article after you have read the corresponding chapter in the book. This article is a companion to Enumerations.
If you are jumping around these articles, make sure you read the Introduction to see my recommendation for setting up a reading environment.
To add a new page, in Xcode:
At this point, you should have read Enumerations in The Swift Programming Language. You should have a Playground page for this chapter with code in it that you generated while reading the book.
The chapter covers how to declare Enumeration types and use Associated Values.
For these exercises, we are going to imagine a simple media playing app.
In your Playground write code to do the following:
Genreand add cases for
genreNamethat takes a
Genrevalue and uses a
switchto return a string with the name of the genre. So, "Jazz" for
.jazzand "Rap" for
CaseIterableand write a
for inloop to print out all of the genres using
genre.rawValueinstead of a
MediaTypeand add cases for
mediaTitlethat takes a
MediaTypevalue and uses a
switchto return a string with the name of the name of the media type. If it's
music, make sure to use the associated
The next article will provide exercises for the Structures and Classes chapter.
