Running app on iOS device "stalls" several mins at "Compile asset catalogs" stage

After a recent Ionic update, running my app through Xcode (or command line) on iOS takes a really long time (several minutes) after each build.

I assume this is something to do with the recent support for xcassets, but beyond that have no insight. Am I the only one experiencing these long delays and does anyone know of a workaround?

Thanks :slight_smile:
