# init(_:) Creates a range set containing the values in the given ranges. ``` init(_ ranges: some Sequence>) ``` ## Parameters `ranges` The ranges to use for the new range set. ## Discussion Any empty ranges in `ranges` are ignored, and non-empty ranges are merged to eliminate any overlaps. As such, the `ranges` collection in the resulting range set may not be equivalent to the sequence of ranges passed to this initializer. --- Copyright © 2026 Apple Inc.
