The license on the IOS GUI: http://facebook.github.io/design/license.html

You can't use any of this in an actual application. So, I make a mock up and show it to someone and then my finished work has to be different from the mock up to avoid copyright infringement? In that situation, I would say I have intentionally defrauded my customer(/employer) and they should refuse to pay (or fire me) and win.

(More likely still, I use them anyway since a graphic artist has made the mock-up and I presume they created or correctly sourced the graphics.)

Summary: I don't see an actual problem here.

"...found in the public release of iOS 9." Facebook can't claim copyright on Apple's UI elements by simply recreating them in a Photoshop mockup.

Upon further reading of the license, I see that it says you can't embed the Facebook Design Resources in an app. In other words, you can't redistribute their Photoshop files.

Now I am even more confused. What is Apple's license on Apple's UI elements that facebook can make this derivative work?

From reading the description it sounded like they were making original elements in the style of Apple's for apps with non-native features that need to blend in.

I'm sure the license that allows me, a 3rd party app developer, to make 'derivative works' (native applications) that use Apple's UI elements, also permits this kind of use. However, I am currently disinclined to read the current developer license agreement to find out if this actually is the case.

You are getting psds of iphone's own user interface...so that you can then put the mock up of your application inside it for say client presentation or to see how your app's design looks on the iPhone or to see if your app's design meshes well with iphone's aesthetics.

I understand how this works in terms of mockups and how useful it can be - where it gets confusing is in tools like Origami which uses Facebook frameworks:

>Origami can now export code for the parts of your prototypes you used to have to tediously spec to engineers. Now with the click of a button, you can deliver your animation specs as code to your engineers that they can copy-and-paste into the project.

> This uses our _free, open source_ animation frameworks to deliver the exact same feel across all platforms. Take a look at some sample code this can generate and learn more about it.

Which runs in direct contrast with the above License:

> The Facebook Design Resources may not be embedded in any software programs or other products without express written permission.

Unless Origami isn't considered a "Facebook Design Resource" (and is a different type of resource, correct me if I'm wrong here), this seems like lawsuit bait.
