After rebuilding one of my projects I am now getting 21 Mach-O Linker errors that all seem to be related to "_videoPlayer...". Is Vuforia comptaible with the latest version of xCode? Perhaps I need to downgrade xCode or Unity to a previous version without the patch update?

For example on iOS SDK 8.1 this would be something like: /Applications/Xcode.app/Contents/Developer/Platforms
