Compile Error using Parse and Facebook

I'm trying to integrate Parse and Facebook's SDK with my app using Xcode 6.3 and am getting these errors when attempting to build:

Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_FBSDKAppEvents", referenced from: __TMaCSo14FBSDKAppEvents in AppDelegate.o "_OBJC_CLASS_$_FBSDKApplicationDelegate", referenced from: __TMaCSo24FBSDKApplicationDelegate in AppDelegate.o "_OBJC_CLASS_$_PFAnalytics", referenced from: __TMaCSo11PFAnalytics in AppDelegate.o "_OBJC_CLASS_$_PFFacebookUtils", referenced from: __TMaCSo15PFFacebookUtils in AppDelegate.o "_OBJC_CLASS_$_Parse", referenced from: __TMaCSo5Parse in AppDelegate.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I don't know what this means, but I've tried many other solutions, such as cleaning, deleting the Derived Data folder, checking all of my frameworks, and I still can't solve the problem. If anyone has any idea how to fix this I would be very grateful. Thank you for your time.
