The app I am developing has a weird issue since a few months. Sometimes during building an archive the error cdtool cannot compile occurs. But only sometimes.
When I wipe the derived-data and do a clean-archive it works again.
I found a variety of people asking similar questions, but they all had this error occur nonstop.
To be precise: The error occurs always during archiving and always on the same file which is Config.xcdatamodel. This CoreData model only has one version so version-conflicts aren't a problem (also verified on the file-system).
Unfortunately it is nearly not reproducable at all, it seems to occur 100% randomly. It also doesn't provide an closer information about what exactly it is, that fails.
In the image there are two compile-errors. Thats because the Config.xcdatamodel that fails, is in both targets. They won't be used at the same time, so it should be fine. I also suspect that the second error-message is based on the first (upper) one.
Did anyone ever observe such a behaviour? I'm currently using XCode 7.2.1
