Apple Mach-O Linker Error

Question

I've just updated to the newest version of unity and xcode and now I'm unable to build to any device. xcode spits out this message to me. I've tried changing build settings, reinstalling unity and xcode, restarting ect. Nothing is working for me. Please help!

I figured it out. I modified AppController.mm to handle a custom url scheme and overwrote the one in to the Xcode project using PostprocessBuildPlayer. To fix it I had to re-merge my custom code with the new AppController.mm.

I also got these errors, with a completely different fix. I had to go to the 'capabilities' tab and activate the (NYI) features that i'd requested for the application id. weird. Switched on iCloud, Game Center and In-App purchases. Apparently, anything not prohibited is mandatory.
