As discussed in this PR:
https://github.com/aerogear/aerogear-ios-http/pull/7

With dependant project you should built them in the order of dependency. Using Xcode dependent project is a workaround as we don't have cocoapods working with swift lib yet.

we should add that to README with:

First Run AGURLSessionStubs target to build Xcode dependent project
Build AeroGearHttp
Run AeroGearHttpTest target

@ ways t go:

• either find a more leegant way with xcode project or workspace
• or at least document it better on README instructions
