错误1:无法将字符串类型的值转换为指定的类型 NSManagedObjectContext **

Error1 : Cannot convert value of type String to specified type NSManagedObjectContext**

错误2:无法将URL类型的返回表达式转换为返回类型URL.

Error2 : Cannot convert return expression of type URL to return type URL.

 class func persistentFileURL(_ name: String, enclosingDirectoryName: String) -> Foundation.URL {
        let directoryURL = self.directoryForPersistentStorage(enclosingDirectoryName)
        let urlPath = directoryURL.path
        let filePath: NSManagedObjectContext = (urlPath as NSString).appendingPathComponent(name) //Error1 : Cannot convert value of type String to specified type NSManagedObjectContext 
        
        return URL(context: filePath) // Error2 : Cannot convert return expression of type URL to return type URL.
