I really enjoyed reading your article. Here are a few minor changes based on newer versions of Swift.
The half-open range operator ..
is now ..<
.
Typed arrays are no longer declared and created using String[]()
; use [String]()
instead.
Your Sort syntax is invalid:
sort([1, 5, 3, 12, 2]) { $0 > $1 }
sort
takes an array as inout parameter, which you aren't passing hereSo this would work:
var numbers = [1, 5, 3, 12, 2]
sort(&numbers)
Or this:
var numbers = [1, 5, 3, 12, 2]
numbers.sort(<)
Or you can return the sorted numbers using sorted
instead of sort
:
let immutableNumbers = [1, 5, 3, 12, 2]
let immutableSortedNumbers = [1, 5, 3, 12, 2].sorted(<)
This is more of a suggestion than a correction. You might want to cover optional downcasting (let movie = object as? Movie
); I don't know if there's a Scala equivalent (I don't know Scala).
