Sort Array with reference of AnyCollection<(label: Optional, value: Any)> in Swift

Question

I'm getting variables of Struct as [Key:Value] inside an array by using Mirror. Mirror returns variables in a sorted order. However, after they are set on array, sort spoils. How can I protect the sort? I try to sort array after set with reference of Mirror.children but can't figure out.

for loop inside function returns a correct and sorted value. Problem is after they are set on result[property] = value, sort spoils. How can I protect the sort?

extension Loopable {

    func allProperties() throws -> [String: Any] {

        var result: [String: Any] = [:]

        let mirror = Mirror(reflecting: self)

        // Optional check to make sure we're iterating over a struct or class
        guard let style = mirror.displayStyle, style == .struct || style == .class else {
            throw NSError()
        }

        for (property, value) in mirror.children {
            guard let property = property else {
                continue
            }
            result[property] = value
        }
        //let sorted = result.sorted{ mirror.children.index(of: $0.key)! < mirror.children.index(of: $1.key)! } TRYING THIS
        return result
    }

}
