just holding onto this for myself: reshuffling an array with generics

arrayMove.swift

let arr = ["a", "b", "c"]
let arr2 = [1, 2, 3]

func moveOver<Item>(_ arr: [Item], start: Int, dest: Int) -> [Item] {
    var out = arr
    let rem = out.remove(at: start)
    out.insert(rem, at: dest)
    return out
}
moveOver(arr, start: 0, dest: 2)
moveOver(arr, start: 2, dest: 0)
moveOver(arr, start: 1, dest: 0)
moveOver(arr, start: 1, dest: 2)
moveOver(arr, start: 0, dest: 1)
moveOver(arr, start: 2, dest: 1)

moveOver(arr2, start: 0, dest: 2)

extension Array {
    func move(start: Int, dest: Int) -> [Element] {
        var out = self
        let rem = out.remove(at: start)
        out.insert(rem, at: dest)
        return out
    }
    
}

arr.move(start: 0, dest: 2)
