值类型“字符串”没有成员“stringByAppendingPathComponent”

我只是将我的项目斯威夫特3，我得到了一个错误directory.path行：值类型“字符串”没有成员“stringByAppendingPathComponent”

Error: Value of type 'String' has no member 'stringByAppendingPathComponent'.

我已经尝试过let realmPath = (directory as NSString).stringByAppendingPathComponent相反，我有以下错误：

Cannot convert value of type 'URL' to type 'NSString' in coercion.

override func awake(withContext context: Any?) { 
    super.awake(withContext: context) 

    let directory: URL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.RazvanJulian.app")! 
    let realmPath = directory.path.stringByAppendingPathComponent("db.realm") /* ERROR */ 

    RLMRealm.setDefaultRealmPath(realmPath) 
    realmToken = RLMRealm.default().addNotificationBlock { note, realm in 
     self.reloadTableData() 
    } 
    reloadTableData() 
}

请检查一下，让我知道。

预先感谢您！

看到这个https://stackoverflow.com/questions/35541747/create-directory-in-app-group-container-swift –

你是强制为具有'stringByAppendingPathComponent'的'NSString'，因此不要施放它 – Jack

stringByAppendingPathComponent斯威夫特3.成为appendingPathComponent试试这个：

directory.appendingPathComponent("component")
