Removes the elements in the specified subrange from the collection.
mutating func removeSubrange(_ bounds: Range<Self.Index>)
The range of the collection to be removed. The bounds of the range must be valid indices of the collection.
All the elements following the specified position are moved to close the gap. This example removes three elements from the middle of an array of measurements.
var measurements = [1.2, 1.5, 2.9, 1.2, 1.5] measurements.removeSubrange(1..<4) print(measurements) // Prints "[1.2, 1.5]"
Calling this method may invalidate any existing indices for use with this collection.
