LoadLevel does not work on iOS devices

Hi,

I got stuck after the upgrade. I used latest Unity version 4 with Unity Script (didn’t want to upgrade to Unity 5 before releasing the game, just to avoid complications). Unfortunately I had to upgrade to iOS9 and to new xCode and xCode started getting the error. The game was built in Unity then opened in xCode, however during deployment on iPhone I started getting error:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

I decide to upgrade also to Unity5. Now xCode deployment to phone works however on the phone I’m not able to load another scene by clicking of GUI button or with timing, it just doesn’t load, however works in unity.

Is there something wrong with Application.LoadLevel (“NewScene"); Or perhaps something else needs to be done or done differently.

Also for some reason rotation of the object stopped working in Unity5 (even in editor)

transform.Translate(Vector3.left GameManager.speed/12 Time.deltaTime, Space.World); GetComponent.().angularVelocity = direction * 500;

Is there anything can be done to fix both issues? Or perhaps I need to downgrade to Unity 4, then how do I fix xCode error (above)?

Thank you
