No Space left on device

Description of the issue

In every iOS build, when we’re trying to generate .ipa for deploy we’re getting the following intermittent error: <unknown>:0: note: IO failure on output stream: No space left on device & FATA[18:07:49] [ENVMAN] - Failed to init at path:write /var/folders/6q/wgy6jtp12w5gzgm9lzcglpqw0000gn/T/bitrise319106669/input_envstore.yml: no space left on device


Xcode 11.3.X, on MacOS 10.14.6 (Mojave)

Hey everyone!

Just wanted to share the answer from our on-site chat, so others can learn from this issue as well :slight_smile:

While 26GB is a lot of space, it’s not difficult to fill this virtual machine. Unfortunately we are not at liberty to increase the size in the near future, so what we’d recommend doing here is try to remove bigger dependencies that get installed during the build - after the build phase of the build.

What could also help is removing unnecessary simulator images that you are not using, those tend to take up a big space.

For example, by issuing the
sudo rm -rf /Library/Developer/CoreSimulator/Profiles/Runtimes/iOS\ 10.3.simruntime/

command, the iOS 10.3 simulator will be removed.

Hope this helps :wink:
