Oops I just realized that the version 6.1.0 of wikitude plugin was included in my project !
I downloaded the sample app on thursday just after the release of SDK 7, and I probably sync with some obsolete cache when importing Wikitude Plugin.
I had some problems with compiling the sample app for iOS, but following the advice of Daniel here, I managed to make it work !

I just tried the new SDK 7 sample app on 2 iOS devices :
