Instance Method


Removes and returns the element at the specified position.


@discardableResult mutating func remove(at position: Int) -> UInt8



The position of the element to remove. position must be a valid index of the collection that is not equal to the collection’s end index.

Return Value

The removed element.


All the elements following the specified position are moved to close the gap. This example removes the middle element from an array of measurements.

var measurements = [1.2, 1.5, 2.9, 1.2, 1.6]
let removed = measurements.remove(at: 2)
// Prints "[1.2, 1.5, 1.2, 1.6]"

Calling this method may invalidate any existing indices for use with this collection.

Complexity: O(n), where n is the length of the collection.
