Swift 5.7, can you use a string to dynamically use a keyPath with Structs?

struct Server: Codable {
 let cats: Int
 let dogs: Int
 let fishies: Int
}

It must be Codable.

let x = Server(cats: 42, dogs: 13, fishes: 777)

We can use keypaths:

print( x[keyPath: \.dogs] )

Which would print "13".

Is there a way to use a string for the keypath? So, something like

let str = ".dogs"
print( x[ keyPath: \$str ] ]

or perhaps

let s = ".dogs"
let k = KeyPath(fromString: s)
print( x[keyPath: k] )

(Note, I appreciate there are any number of other approaches, eg, use sql, dictionaries, switch statement, etc etc. The question at hand is as stated, TY)

For the record, the answer is No, you cannot, as of Swift5.

If you need to access struct fields, by string (for example in a typical "column definition" setup), just IMO the best thing to do is simply something like ...

func structField(viaString key: String) -> String {
    switch key {
    case "height": return String(self.height)
    case "lat": return self.lat
    case "long": return self.long
    ... etc
    ... etc

which would vary in your use case.
