+=(_:_:)
Appends the elements of a sequence to a range-replaceable collection.
static func += <Other>(lhs: inout Self, rhs: Other) where Other : Sequence, Self.Element == Other.Element Parameters
Use this operator to append the elements of a sequence to the end of range-replaceable collection with same Element type. This example appends the elements of a Range<Int> instance to an array of integers.
var numbers = [1, 2, 3, 4, 5]
numbers += 10...15
print(numbers)
// Prints "[1, 2, 3, 4, 5, 10, 11, 12, 13, 14, 15]"Other members in extension
Type members
init<S>(S) Creates a new instance of a collection containing the elements of a sequence.
init(repeating: Self.Element, count: Int) Creates a new collection containing the specified number of a single, repeated value.
static func + <Other>(lhs: Other, rhs: Self) -> Self Creates a new collection by concatenating the elements of a sequence and a collection.
static func + <Other>(lhs: Self, rhs: Other) -> Self Creates a new collection by concatenating the elements of a collection and a sequence.
static func + <Other>(lhs: Self, rhs: Other) -> Self Creates a new collection by concatenating the elements of two collections.
Instance members
func append(Self.Element) Adds an element to the end of the collection.
