Sorry to bump an older thread. I'm currently experiencing this problem of getting a black screen and the game failing to start. But reports are that its happening with iOS 9, while iOS 10 is ok.
My game runs fine on my test device which is running iOS 10, but some players have reported the black screen issue and they all seem to be using iOS 9. Discussion on TouchArcade where players are discussing this problem (end of page 1 and onto page2).
Im using the latest XDK (3759) and C2 beta 241, but I noticed that the Cordova WKWebView Engine plugin is version 1.0.3, not the latest 1.1.0. Ill try updating this and making a new build. Are there any other possibilities for what could be causing a black screen on devices running iOS 9 that I should also look at?
— hope you dont mind me tagging you. You seemed to have researched this pretty thoroughly back in Oct.. Can I ask your opinion?
