Parse for iOS: Errors when trying to run the app

Question

I've been working with the Parse SDK and I followed the quickstep guide. When I try to run, I get these 8 errors. Any ideas as to why? It looks like something to do with the Facebook part of Parse which I'm not using.

 Undefined symbols for architecture armv7:

Answer 1

This is some sort of bug associated with the Parse iOS 1.1.33 release as multiple people are seeing the same errors- myself included.

There are a couple of workarounds-

If you're not using a library which requires the -ObjC linker flag, you can remove -ObjC from your project:

Build Settings > Other Linker Flags > remove -ObjC

or if you are using a library which requires that flag, you can add the Facebook SDK.

Both options will eliminate the errors. Hopefully they fix this as I have no need for the Facebook SDK in my app.
