Any ideas?

Hi @all,

If you have a crash like that, please send us a demo project with which we can reproduce the issue or send the complete stack trace file to us so that we can see where it crashes. Another option would be to find a way that we can reproduce it with our example app.


Best regards,

I have the same problem, i am using SDK 8, but i am not using storyboard, i am controlling al the views programmatically. When i try to go to the ArchitectView VC i get that error

Hi @all,

Our JS API example app has the same setup (launching another view controller once an example was selected). Can you reproduce the described behavior with that example app as well?


Did you had a chance to try our latest release, SDK 8 already?

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.

Hi,

Which version of our SDK are you using?


Best regards,
Andreas
