How do I add a tuple to an array in Swift?

[kjmcneish]

There are a few ways to add a tuple to an array of tuples. For example, Here is a tuple array declaration:

Code: [Select]

var results = Array<(code: Int, message: String)>()
It declares an array of named tuples that have Int (code) and String (message) values.

You can use the compound assignment operator to append a tuple to the array. Notice how the tuple is nested within square brackets :

Code: [Select]

results += [(code: 1, message: "Invalid Date")]
You can also use the Array's append method, which doesn't require the square brackets:

Code: [Select]

results.append(code: 1, message: "Invalid Date")
All the best!
