According to Starscream's docs we want to add Starscream in both "Link Binary with Libraries" as well as "Copy Frameworks" (a "Copy Files" Build Phase that sets the destination to "Frameworks"). When I do the second step, I get the following error:
Unable to run command 'PBXCp Starscream.framework' - this target might include its own product.
