Swift之判断路径隐藏状态

判断路径隐藏状态：

func fileUrlIsInvisible(_ fileUrl: URL) -> Bool {
        let myUrl = fileUrl
        var isHidden: AnyObject?
        
        var keys = Set<URLResourceKey>()
        keys.insert(URLResourceKey.isHiddenKey)
        do{
            isHidden = try myUrl.resourceValues(forKeys: keys) as AnyObject
            return (isHidden as? NSNumber)?.boolValue ?? false
        } catch let error as NSError {
            print(error.debugDescription)
            return false
        }
    }
