我制作Flutter应用程序。然后最近恰好无法在iOS模拟器上运行应用程序。我想原因是Xcode升级，但不太清楚。
你有什么办法帮它吗？非常感谢。

FIXED，在我的案例中是文件权限问题，有flutter管理员的帮助。https://github.com/flutter/flutter/issues/94692
但我认为根本原因是错误提示不明显，你可以看看调查步骤来了解原因，你可以找到你的解决方案
尝试更新pod，转到ios文件夹，运行pod deintegrate，然后运行"pod install"。如果这没有帮助，则运行pod update或"pod repo update"。试着找出哪个包出现问题，并更改它们的版本。
通过将Flutter版本从2.5.3升级到2.8.1，解决了此问题。
