Actually, it's quite simple with Swift. As mentioned in the Apple's doc, you can initialize an array with the same repeated value like this:

With old Swift version:

var threeDoubles = [Double](count: 3, repeatedValue: 0.0)

Since Swift 3.0:

var threeDoubles = [Double](repeating: 0.0, count: 3)

which would give:

[0.0, 0.0, 0.0]
