Hi, I have a similar problem running Xcode 8.3.3 on OS X 10.12.6 iOS target 10.3
After completing the steps in the tutorial I get ‘Use of undeclared type’ errors on all OE references, specifically OEEventsObserverDelegate and OEEventsObserver.
The OpenEars sample app works fine. But I could not integrate into my project, and I too tried starting a very simple single view app from scratch and followed the tutorial with no success.
OpenEars.framework and Slt.framework do show up in the Linked Frameworks and Libraries…
