How to tell if an array contains an object

Written by Paul Hudson    @twostraws

It's easy to find out whether an array contains a specific value, because Swift has a contains() method that returns true or false depending on whether that item is found. For example:

let array = ["Apples", "Peaches", "Plums"]

if array.contains("Apples") {
    print("We've got apples!")
} else {
    print("No apples here – sorry!")
}

That example array does indeed contain "Apples" so that code will print "We've got apples!" to the Xcode console.
