+(_:_:)
Creates a new collection by concatenating the elements of a collection and a sequence.
static func + <Other>(lhs: Self, rhs: Other) -> Self where Other : Sequence, Self.Element == Other.Element Parameters
The two arguments must have the same Element type. For example, you can concatenate the elements of an integer array and a Range<Int> instance.
let numbers = [1, 2, 3, 4]
let moreNumbers = numbers + (5...10)
print(moreNumbers)
// Prints "[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]"The resulting collection has the type of the argument on the left-hand side. In the example above, moreNumbers has the same type as numbers, which is [Int].
