NSObject_Extensions.swift

extension NSObject {
    
    private enum SetValuableErrorType: Error, CustomStringConvertible {
        case unknown(key: String, type: NSObject)
        
        var description: String {
            switch self {
            case .unknown(key: let k, type: let t):
                return "Unknown parameters \(k) for object typped \(String(describing:t))"
            }
        }
        
    }
    
    func set(value: Any?, forKey key: String) throws {

        guard let _ = self.value(forKey: key) else {
            throw SetValuableErrorType.unknown(key: key, type: self)
        }
        
        self.setValue(value, forKey: key)
