Ios 无法符合objective-c中的swift委托协议

我正在一个objective C项目中使用swift pod。
我成功地从objective-c访问了swift类，无论如何，我面临着采用swift协议的问题。
编译器没有抱怨，生成的桥接头似乎正确

调用

[self.sceneLocationView setLocationNodeTouchDelegate:self]时在运行时出现问题[ARCL.SceneLocationView setLocationNodeTouchDelegate:]的代码>：发送到实例的选择器无法识别

我找不到这个问题的任何解决方案，我花了时间在这里搜索，但仍然没有成功。

任何帮助都将不胜感激。

谢谢

我的swift和objective-c文件如下所示

[self.sceneLocationView setLocationNodeTouchDelegate:self]；如果您只使用简单赋值
self.sceneLocationView.locationNodeTouchDelegate=self；
，会发生什么情况？同样，这会导致相同的运行时错误。在这里工作。使用Xcode 11.2进行测试。我刚刚使用
sceneLocationView:UIView
进行测试。原因似乎不在提供的代码中。感谢您的测试@Asperi，我正在使用X代码10.2，因为我的mac太旧了，无法安装最新的Xcode 11。你使用了swift 5吗？Xcode要求我将swift 4.2转换为5Works，以及macOS 10.13.6/Xcode 9/swift 4.0。我没有这些版本。这可能是pod或项目配置中的原因，但Objective-C swift bridge肯定没有问题。
