# sort(_:sortOrder:) Sorts a vector of double-precision values in-place. ``` static func sort(_ vector: inout V, sortOrder: vDSP.SortOrder) where V : AccelerateMutableBuffer, V.Element == Double ``` ## Parameters `vector` The array to sort. `sortOrder` The sort order. ## Discussion The single- and double-precision [`sort(_:sortOrder:)`](/documentation/Accelerate/vDSP/sort(_:sortOrder:)-wx0w) functions sort an array in place. The following code sorts an array in ascending order, followed by decending order: ```swift var values: [Float] = [4.0, 8.0, 3.0, 0.0, 7.0, 5.0, 9.0, 2.0, 6.0, 1.0] vDSP.sort(&values, sortOrder: .ascending) // Prints "[0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0]". print(values) vDSP.sort(&values, sortOrder: .descending) // Prints "[9.0, 8.0, 7.0, 6.0, 5.0, 4.0, 3.0, 2.0, 1.0, 0.0]". print(values) ``` --- Copyright © 2026 Apple Inc.
