I'm encountering an issue with the latest versions of Xcode (15.1 and 15.2) while programming in Objective-C. When I try to create a category or an extension for a class, the process does not succeed and there is no response, with the category file not being created. This problem was not present in Xcode 15.0.1. My development environment is macOS Ventura 13.6.1. This bug is affecting my development work significantly. Could you please investigate this issue and provide a solution? Thank you for your assistance. 我在使用最新版本的Xcode（15.1和15.2）进行Objective-C编程时遇到了一个问题。当我尝试为一个类创建分类或扩展时，过程并不成功，没有任何反应，且分类文件没有被创建。在之前的版本Xcode 15.0.1中并没有这个问题。我的开发环境是 macOS Ventura 13.6.1。这个bug严重影响了我的开发工作。您能否调查此问题并提供解决方案？感谢您的帮助。
