Hi guys i'm receiving this error while try to run the Xcode project, i'm using Buildbox 2.1 and tried X code 6.4 and 7.3 both gives the same error.
Sound like Vungle library was not added to your project... I am still on 1.3.6 and for me it is called libPTAdVungle.a if that helps? It should be in the Frameworks folder or you can also check it in the Build Phases / Link Binary With Libraries...
