FigVirtualFramebufferServer:不支持的操作

FigVirtualFramebufferServer: Unsupported Operation

我在尝试 ARKit 时出现黑屏并显示以下错误消息。 WWDC 2017 示例 PlacingObjects 在同一设备上 运行 没有问题。

[] <<<< FigVirtualFramebufferServer >>>> FigVirtualFramebufferGetMaxCount: unsupported operation
[] <<<< FigVirtualFramebufferServer >>>> FigVirtualFramebufferGetFramebufs: unsupported operation
[] <<<< FigVirtualFramebufferInstallation >>>> FigInstallVirtualDisplay_block_invoke: FigVirtualFramebufferGetFramebufs failed (0 framebufs)

缺少什么?

因为info plist中的设置"PrefersOpenGL"发生了。
