實例方法
append(_:)
將元素添加到集合的末尾。
聲明
mutating func append(_ newElement: Self.Element)
參數
newElement
要附加到集合的元素。
詳述
如果集合沒有足夠的容量容納另一個元素,則會在附加 newElement
之前分配額外的存儲空間。以下示例將一個新數字添加到整數數組中:
var numbers = [1, 2, 3, 4, 5]
numbers.append(100)
print(numbers)
// Prints "[1, 2, 3, 4, 5, 100]"
可用版本
iOS 8.0+, iPadOS 8.0+, macOS 10.10+, Mac Catalyst 13.0+, tvOS 9.0+, watchOS 2.0+
