Xcode 为什么我得到这个错误无法为模拟器构建应用程序。在iPhone 11 Pro Max上启动应用程序时出错？

当我试图在iOS emulator上运行我的应用程序时，我收到了这个错误 有人知道我为什么会得到这个吗

这个应用程序在上周运行得很好，但我不知道为什么它现在不能运行

在从用户@Huthaifa Muayyad处进行了一些更改之后，这就是现在的错误

尝试取消对第一行ios/Podfile的注释，并将其更新为

10.0

您的错误还表明，

UIAlertView已弃用。将UIAlertController与首选样式UIAlertControllerStyleAlert一起使用

如果您正在使用它，请尝试更新imagepicker。

我做了您想做的事情，但现在遇到另一个错误我将更新我的帖子请签出OK请检查它告诉您

错误：调用中缺少参数标签“preferredTimescale:”

这是什么意思？检查这条线
