我试图在swiftUI中使用AR，但不支持配置我的设备是iPhone 7plus

我试图用swiftUI放置AR对象，但不支持配置显示，因此我的设备是iPhone 7plus

''' 如果是ARWorldTrackingConfiguration.SupportsGenereConstruction（.mesh）{ config.sceneReconstruction=.mesh

    } else {
        print(UIDevice.modelName)
        print("config not supported")
    }

这个if不起作用，它不在“else”语句中 '''
