我安装了
Xcode 10并将我的iOS应用程序升级到
Swift 4.2.当我通过Xcode运行我的测试(UI和单元)时,在运行iOS 12的iPhone模拟器上,测试成功启动.当我尝试在运行先前iOS版本(例如iOS 10.3.1)的模拟器上运行测试时,我得到“无法加载测试包”.这些测试在Xcode 9.4上成功运行.我可以在这个旧的模拟器上运行我的应用程序而不会出现问题.
Xcode输出如下(“Reading List”是应用程序名称)：

线路mach-o,但不是为iOS模拟器构建的,似乎它可能是关键.我该如何解决这个问题？
测试目标将iOS部署目标设置保留为默认值.
在Xcode 9.4中,这等于“iOS 11.4”,但由于某种原因,测试仍然可以在“iPhone 7(10.3)”模拟器上运行.在Xcode 10中,似乎行为发生了变化,因为测试不再运行在默认“iOS 12”之前运行iOS版本的模拟器上.
