关于Objective C：构建带有资产目录的tvOS应用时出现错误

Error when building tvOS app with asset catalogs populated

我正在尝试构建一个简单的tvOS应用程序示例。如果我使用没有图像的资产目录，则没有构建问题，但是如果我在资产目录中添加"大图标"(1280x768)，则编译器在构建后会出现以下错误：

1 2	The image stack"App Icon - Small" must have at least 2 layers with applicable content. Although it has 3 layers, none have applicable content
