无法在模拟器上构建模块“UIKit”，但不能在电话上构建模块

Question

当我试图在iphone模拟器5、6和6+上构建我的项目时，我收到了以下错误。我试图再次清理和重建，但没有工作。我不知道为什么会发生这种事。因为当我插上我的手机时，它会在手机上正常运行。

这里最重要的错误是UIKit和QuarztCore都是毫无根据的。

有人能调查一下吗？我如何解决这个问题，以便我可以运行我的应用程序模拟器！谢谢!

原因不是StoreKit。也许“CAMetalLayer”是因为它需要A7设备(而不是模拟器)。

更新： ref/doc/uid/TP40012848-CH4-SW1

您可以在此链接中找到模拟器中不支持的API。显然，苹果已经把StoreKit从这个名单上删除了。所以也许，原因不是StoreKit。也许'CAMetalLayer‘因为
