SIGABRT 在 macCatalyst 中随机“以下金属对象正在被销毁，同时命令缓冲区仍要求其处于活动状态”

Question

我的 macCatalyst 应用程序最近发生了一些随机崩溃。到处寻找但没有找到任何好的线索。我的猜测是，这与内存或屏幕上可见的视图太多有关。我没有得到很好的堆栈跟踪，但这就是日志中显示的内容：

我正在配备 32Gb 内存的 Intel Mac mini 上运行。在屏幕上显示 MapView 时，它经常崩溃。但在其他一些情况下也是如此。

编辑：可能与在 MacCatalyst 上的 MapView 中以编程方式放大动画有关。目前的解决方法是禁用动画。会进一步研究。

此开发者论坛帖子建议禁用 Metal API 验证。我遇到了同样的问题，这似乎解决了它。

在 Xcode 中，在“产品”菜单中，转到“方案”，然后“编辑方案...”。在左侧面板中选择“运行（调试）”，然后在“诊断”选项卡中取消选中 Metal 设置下的“API 验证”
