When I build this project with strip enabled, things start to break in the app. Previously if I built with strip bytecode it would not start up. Taking it down to strip assemblies would fix it. Now that I’ve started using some of the GUILayout code, strip assemblies starts to break functionality. Some UI’s won’t appear and the framerate goes down. Am I doing something wrong? Are there known issues with this?
Thank you. 
Is anyone using iPhone stripping Strip Bytecodes?
Hello,
Please submit bug report with sample project attached to it and PM bug number to me.
Just submitted… 
I’ve had a similar problem. It was mentioned and reported in the thread http://forum.unity3d.com/viewtopic.php?t=17056&highlight= and it sounds like it will be fixed in the next iPhone release.
Thanks for pointing out that thread. Part of the problem mentioned in the thread sounds very similar to mine, but when not using the UI components at full iPhone strip level “strip bytecodes” my project doesn’t run at all which sounds like it could be a different issue.
