[Swift] Mirror 써보기

class User: NSObject { // setValue 는 NSObject 의 method
    @objc var login: String = "raw" // string -> key 로 접근 가능
}

func hasProperty(_ name: String, object: AnyObject) -> Bool {
    let mirror = Mirror(reflecting: object)
    for (label, _) in mirror.children {
        if label == name { return true }
    }
    return false
}

var user = User() // login: "raw"
let parameters: [String: Any] = ["login": "octodog"]

for (key, value) in parameters {
    guard hasProperty(key, object: user) else { continue }
    user.setValue(value, forKey: key)
}

print(user.login) // login: "octodog"
