Long iOS Incremental Build Times even with Library Caching Enabled

Unity Services

Hello,

We’re seeing 1-2 hour incremental builds times.

Library caching is enabled:

We’re getting these long build times with any change. For example, even just adding a missing .meta file:

Any ideas?

Thanks,

This is a known issue with SVN specifically. With our current svn support, the last-modified timestamps for files are not properly applied when the checkout happens, which causes most of the the assets to be unnecessarily re-imported in Unity. For a project this size, that re-import is not going to be quick. It’s something we are actively working on fixing, however I don’t have a definite date it will be ready.

Just as note - Git and Perforce shouldn’t have this issue in our system (I know that’s not helpful in your specific case, just wanted to mention it for others that might see this thread).

Thanks for replying. That’s actually super helpful. I tried a fancy SVN → Git mirroring solution (SubGit), but it’s not available for hosted SVN. So we went ahead and moved over temporarily to Git on GitHub and are now seeing incremental build times that are about two-thirds faster (0.5 hours instead of 1.5 hours). Thanks!
