Xcode 9 and older xib files

We have a fairly old project, and we decided to test whether it will compile with Xcode 9. It seems that we have a problem compiling old xib files - we have encountered this error:


"Compiling IB documents for earlier than iOS 7 is no longer supported."


To try to get around this, we changed the deployment target to 8.2 for this particular xib file, and we changed the iOS deployment target to 8.2, but we still get this error! How do we get rid of this error? Do we have to recreate new xib files (I really hope not).

>but we still get this error!


Did you option-clean build folder after that change?


When selecting the xib(s), what is the setting on the right...File Inspector/Interface Builder Document/builds for...?


Note I can build an older app w/XIBs via Xcode 9b without that same error.
