提问by user1257220

Im very new to iOS programming. Im literally just trying to compile an empty project which as far as I know should work but I'm running into an error:

Just wondering does anyone have any solutions or ideas at what I am doing wrong?

只是想知道有人对我做错了什么有任何解决方案或想法吗？

You're most likely out of disk space. Where is your build folder located? It might not be allowed to write and causing that error.

您很可能没有磁盘空间。您的构建文件夹位于何处？可能不允许写入并导致该错误。

Had this issue, tried most things, but in the end an OSX reboot solved the problem for me.

遇到了这个问题，尝试了大多数事情，但最终 OSX 重新启动为我解决了这个问题。

Derek is correct. In my case the RAM disk I use for XCode derived data was full.

德里克是对的。就我而言，我用于 XCode 派生数据的 RAM 磁盘已满。
