get · iOS 13.0+

startIndex

TypeScript
get startIndex(): number
Swift declaration
var startIndex: Int

The position of the first element in a nonempty collection. If the collection is empty, `startIndex` is equal to `endIndex`.

set · iOS 13.0+

startIndex

TypeScript
set startIndex(value: number)
Swift declaration
var startIndex: Int

The position of the first element in a nonempty collection. If the collection is empty, `startIndex` is equal to `endIndex`.

method · iOS 13.0+

index

TypeScript
index(i: number): number
Swift declaration
func index(after i: Int) -> Int

Returns the position immediately after the given index. The successor of an index must be well defined. For an index `i` into a collection `c`, calling `c.index(after: i)` returns the same index every time. - Parameter i: A valid index of the collection. `i` must be less than `endIndex`. - Returns: The index value immediately after `i`.

endIndex

TypeScript
get endIndex(): number
Swift declaration
var endIndex: Int

The collection's "past the end" position---that is, the position one greater than the last valid subscript argument. When you need a range that includes the last element of a collection, use the half-open range operator (`..<`) with `endIndex`. The `..<` operator creates a range that doesn't include the upper bound, so it's always safe to use with `endIndex`. For example: let numbers = [10, 20, 30, 40, 50] if let index = numbers.firstIndex(of: 30) { print(numbers[index ..< numbers.endIndex]) } // Prints "[30, 40, 50]" If the collection is empty, `endIndex` is equal to `startIndex`.

subscript · iOS 13.0+

subscript

TypeScript
subscript(sample: number): CMSampleBuffer_PerSampleAttachmentsDictionary
Swift declaration
subscript(sample: Int) -> CMSampleBuffer.PerSampleAttachmentsDictionary { get set }

Accesses the element at the specified position. The following example accesses an element of an array through its subscript to print its value: var streets = ["Adams", "Bryant", "Channing", "Douglas", "Evarts"] print(streets[1]) // Prints "Bryant" You can subscript a collection with any valid index other than the collection's end index. The end index refers to the position one past the last element of a collection, so it doesn't correspond with an element. - Parameter position: The position of the element to access. `position` must be a valid index of the collection that is not equal to the `endIndex` property. - Complexity: O(1)
