Declaration
static func + <Other>(lhs: Array<Element>, rhs: Other) -> Array<Element> where Other : RangeParameters
lhsA range-replaceable collection.
rhsAnother range-replaceable collection.
Discussion
The two arguments must have the same Element type. For example, you can concatenate the elements of two integer arrays.
let lowerNumbers = [1, 2, 3, 4]
let higherNumbers: ContiguousArray = [5, 6, 7, 8, 9, 10]
let allNumbers = lowerNumbers + higherNumbers
print(allNumbers)
// 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, more has the same type as numbers, which is [Int].
