Sort Swift Array of Dictionaries by Value of a Key

Question

I am attempting to sort a Swift array which is composed of dictionaries. I have prepared a working example below. The goal is to sort the entire array by the \"d\" element in t

Answer 1

edit/update: Xcode 11 • Swift 5

var array: [[String:Any]] = []
var dict: [String: Any] = [:]

dict["a"] = "hickory"
dict["b"] = "dickory"
dict["c"] = "dock"
dict["d"] = 5

array.append(dict)

dict["a"] = "three"
dict["b"] = "blind"
dict["c"] = "mice"
dict["d"] = 6

array.append(dict)

dict["a"] = "larry"
dict["b"] = "moe"
dict["c"] = "curly"
dict["d"] = 2

array.append(dict)

let sortedArray = array.sorted { $0["d"] as? Int ?? .zero < $1["d"] as? Int ?? .zero }

print(sortedArray)  // "[[b: moe, a: larry, d: 2, c: curly], [b: dickory, a: hickory, d: 5, c: dock], [b: blind, a: three, d: 6, c: mice]]"
