简单创建SCNNode时抛出NSSecureCoding

Question

我正在尝试从我的.scn (最初是我转换为.scn的DAE文件)创建一个SCNNode，执行此操作时，控制台会生成以下内容：

[general] NSSecureCoding allowed classes list contains [NSObject class],
which bypasses security by allowing any Objective-C class to be implicitly
decoded. Consider reducing the scope of allowed classes during decoding by
listing only the classes you expect to decode, or a more specific base class
than NSObject.

这是导致抛出的代码：

if let usrScene = SCNScene(named: "Test.scnassets/Models/player.scn") {
    usr = usrScene.rootNode.childNode(withName: "root", recursively: true)!
}

场景图如下: root->player

我怎样才能移除掷物(或者我应该)？用外行人的话来说，这是什么意思？

对于那些有相同问题的人：

我从来没有想过抛出是什么意思，但我用下面的代码设法摆脱了它：

extension SCNNode {
    convenience init?(daePath: String) {
        self.init()

        guard let scene = SCNScene(named: daePath) else {
            return
        }

        for childNode in scene.rootNode.childNodes {
            addChildNode(childNode)
        }
    }
}

然后像这样导入...

usr = SCNNode(daePath: "Test.scnassets/Models/player.dae")
