SWIFT reflect all implementations of a certain protocol

I want to use SWIFT reflection to resolve all implementations of a certain protocol.

The problem I'm trying to solve is that I want to test all present and future implementations of a certain protocol.

The reflection in SWIFT is limited, but after reading up on it, I believe it should be possible. I have found the following articles on reflection in SWIFT, but I am having trouble mapping it in to my specific use case.

How can I resolve and iterate over all implementations of a specific protocol?

protocol Animal {
    var color: UIColor { get }
    var name: String { get }
}

class Cat: Animal {
    var color: UIColor = .red
    var name: String = "Joshua"
}

class Dog: Animal {
    var color: UIColor = .blue
    var name: String = "Anna"
}

class Animals {
    var animalCollection: [Animal]
    
    init() {
        ...
    }
}

class TestAnimals {
    func testAnimalCollection() {
        let mirror = Mirror(reflecting: Animals.self)

        for child in mirror.children {
            print(child.value)
        }
    }
}
