Having issues with Vuforia

Hi everybody,

I imported vuforia on a Google Cardboard Project to make Augmented Reality.

Now i edited some stuff and I dont need Vuforia no more, i tried to remove any Vuforia component (in Unity) but then i got some issues while building with XCode.

Also removed vuforia libs & other stuff from linking in build phase from XCode and it compiles but i get app crashes (not even starting).

Can anybody help me?

Using:
Unity 5.3, Latest cardboard, latest vuforia, latest XCode
