除非模拟器是 XS 类型，否则屏幕上的按钮不起作用

Question

基本上我的应用程序运行良好，但是当我尝试在 Xcode 中的 XS 模拟器以外的任何其他模拟器上运行它时，主菜单按钮不再起作用，而且我没有去哪里寻找错误，因为什么也没有正在抛出任何错误。此外，当我将打印语句放在节点内时，打印语句会打印到控制台，告诉我屏幕正在检测选择，但由于某种原因，代码无法运行。这很奇怪，因为它是被调用函数中的一个简单 if else 语句，所以我看不出它不应该运行的原因。

一般来说 spriteKit/Metal 等在模拟器中不起作用！

你必须构建到手机！

它可能只是“巧合地”在新的 XS 模拟器中工作。就是这样。仅适用于手机。
