Xcode:无法加载 ModelIO.framework、SceneKit.framework 等 [英] Xcode: could not load ModelIO.framework, SceneKit.framework, etc

问题描述

在更新到 macOS Mojave 之前，我的应用程序运行良好，没有错误，但是，我在更新后收到此错误.我已经谷歌搜索了 2 天，但似乎还没有人遇到过这个错误.注意:该应用确实按预期运行.3D模型文件为.scn格式.

Before updating to macOS Mojave my app ran fine without errors, however, I get this error after the update. I have been Googling for 2 days but it seems no one has run into this error yet. Note: The app does run as expected. The 3D model file is in the .scn format.

该错误现已无故消失.它以前发生过.错误出现，消失，然后再次出现.奇怪.

The error has now disappeared without any reason. It's happened before. The error shows up, disappears, then shows up again. Strange.

推荐答案

我的原因是命令行工具设置为空.我通过在 XCode 菜单 > 首选项 > 位置中设置命令行工具来解决.

My cause was that the command line tools setting was empty. I solved by setting Command Line Tools in XCode Menu > Preference > Locations.
