realm ignoredProperties（）显示错误

Question

我已经应用了两种忽略var photos = Array<RLMFile>()的方法，但这两种方法在swift中都显示错误。我用方法写下了错误。

1.  public class func ignoredProperties() -> [AnyObject] {
        return ["photos" as AnyObject]
    }////this method give error :- method ignoredProperties() with objective-C selector 'ignoredProperties' conflicts with method 'ignoredProperties() from superclass
2.     override class func ignoredProperties() -> [AnyObject] {
        return ["photos" as AnyObject]
    }//this method give error :- Method does not override any method from its superclass
