Any ideas?

Hi,

Which version of our SDK are you using?


Best regards,
Andreas

I get the same problem using the July 4th build of the SDK whenever I attempt to launch a ViewController that starts the Wikitude SDK from anywhere other than being the initial view controller. If my initial view controller simply has a single button that then launches the view controller that starts wikitude, I get this exact same crash.
