Go to Build Phases -> Link Binary with Libraries Add your third party library to this. If you could not find your library, click Add other.

Have you added the library path to Build Settings -> Libraries Search Path? Check at Build Settings -> Link Binary With Libraries that your library is added also.

Ahh, isn't Xcode great ?

What I would recommend is this: Click on your project in the left panel, then check your architecture settings in both the Project and the Targets sections. enter image description here

And if you have any third-party projects within your project, do the same for them aswell.

(I had to do this when building an Xcode project which used the MapBox iOS SDK library. Annoyingly, you do need to check this setting in each of the various Build Settings tabs, otherwise Xcode will complain.)
