Single-line Comments
Single-line comments are created using two consecutive forward slashes. The compiler ignores any text after //
on the same line.
// This line denotes a comment in Swift.

Multiline comments are created using /*
to begin the comment, and */
to end the comment. The compiler ignores any text in between.
/*
This is all commented out.
None of it is going to run!
