| Classification: | Serious Bug | Reproducible: | Always |
Summary: While using the beta is noticed that my hard drive kept running out of space. Every time I cleared more space, I would be out of space again within a few hours. I ran daisy disk and tracked down a lot of large files. All of the files are inside directories named "(A Document Being Saved By Xcode X)" where X is an incrementing number every time a new one is created. The folders containing the files are located in the directory at path "/private/var/folders/fn/zl6yy3ln68q26v7x_xn4ncsr0000gn/T/TemporaryItems" The file it creates is called "dyld_shared_cache_arm64" and is always exactly 1.07GB, but has a unique md5 hash every time. Steps to Reproduce: 1. Install and use Xcode 9 beta 5 2. Observe hard drive filling up 3. Browse to directory listed above and see that Xcode has been creating a new 1.07GB file every few minutes Expected Results: Xcode should not create endless new large files Actual Results: Xcode consumes my entire hard drive space until everything stops responding and I have to reboot and clear files. Version: Version 9.0 beta 5 (9M202q) Notes:

I had exactly the same issue, I suspect problem with "preparing for debugging" after connecting device with iOS version unknown to Xcode. It started happening after updating my iPad to iOS11b6, and stopped after I deleted contents of
iOS DeviceSupportdirectory manually (with Xcode turned off).
