## Discussion

Discussion 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) print(measurements) // Prints "[1.2, 1.5, 1.2, 1.6]" Calling this method may invalidate any existing indices for use with this collection. note: O(n), where n is the length of the collection.
