This article is part of a series on learning Swift by writing code to The Swift Programming Language book from Apple. This is the seventh 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 Subscripts.
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 Subscripts 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 Subscripts inside of Structures and Classes
For these exercises, we are going to imagine a simple media playing app.
In your Playground write code to do the following:
songsand initialize it with a few names of songs. For example:
"Style", "Shake it Off", "Bad Blood", "Welcome to New York"
countthat returns the count of the
subscriptgetter that takes an
indexand returns the corresponding song from the
countand the subscript to get the names of the songs.
The next article will provide exercises for the Inheritance chapter.
