请原谅这里的任何错误，我是一名编码爱好者，也是新手问的问题，但我已竭尽全力来查找此错误并失败了。
我在SKScenes之间移动时遇到崩溃，但前提是该应用程序已进入后台模式并从后台模式还原。而且崩溃仅发生在实际设备上，而不发生在模拟器上。控制台的输出是这样的：

libc++abi.dylib: terminating with uncaught exception of type NSException
我从中收集到一个我试图访问数组中不存在的索引的地方，但是我不知道它在哪里。
我在SO中搜索了类似的错误，并且遇到了引发异常时激活断点的建议。我已经做到了，并且在“旧”场景被取消初始化之后，代码似乎立即中断。似乎在[SKScene dealloc]之后立即在线程中引发了异常。
这似乎是引发异常的代码（这对我完全没有帮助！）
deinit {
print("Game Scene deinitialised")
}
这是否意味着在释放过程中发生了导致崩溃的事情？我很乐意发布一些代码片段，但不知道从哪里开始。 SKScene非常复杂。
这是主线程崩溃时的样子-＃17显然出了所有问题
