Swift KeyPath Sorting Retrofit

A convenient extension to the Sequence protocol that allows you to sort elements in a Swift-like way. It is inspired by the SortDescriptor implementation in iOS >= 15, and the Swift by Sundell article on sorting Swift collections. If your minimum project target operating system version is iOS >= 15, you should use the Apple-proprietary SortDescriptor.

Example

struct SomeSortableStructure {
    let id: Int
    let isSelected: Bool
    let title: String
    let description: String?
}

struct SorterGuy {
    func sort(_ items: [SomeSortableStructure]) -> [SomeSortableStructure] {
        items.sorted(using: [
            .keyPath(\.title, order: .ascending),
            .keyPath(\.isSelected, order: .descending),
            .keyPath(\.description, order: .ascending),
            .keyPath(\.id, order: .ascending)
        ])
    }
}

Installation

The implementation is quite compact so in most cases it can be just copied to the target project.
