已确认是.storyboard文件导致的编译失败，我们尝试使用XCode打开你提供的storyboard，会导致XCode崩溃。
大概是以下约束条件导致XCode编译失败，建议使用XCode15.2重新创建storyboard文件，注意不要用其它工具编辑storyboard文件。

在使用 Uni-app 开发跨平台应用时，如果自定义启动页面（splash screen）在 iOS 打包时出现报错，可能是由于以下几个原因导致的。以下是一些常见的解决方案：
1. 自定义启动页面的配置问题
- Uni-app 默认使用原生启动页面，如果你自定义了启动页面，可能需要配置
manifest.json和原生工程。 - 在
manifest.json中，确保正确配置了启动页面的路径和图片资源：{ "app-plus": { "splashscreen": { "autoclose": true, "waiting": true, "image": "static/splash.png" } } } - 确保
static/splash.png文件存在，且路径正确。
2. iOS 启动页面的原生配置
- Uni-app 的启动页面在 iOS 上是通过原生工程实现的。如果你自定义了启动页面，可能需要修改原生工程的配置。
- 打开
HBuilderX，选择manifest.json文件，点击源码视图，找到app-plus->splashscreen配置。 - 确保配置了
ios平台的相关参数：{ "app-plus": { "splashscreen": { "ios": { "image": "static/splash.png", "contentMode": "scaleAspectFill" } } } }
