Thanks Rick, that worked perfectly. Is there a reason that the target and the AFNetworking statements use single quotes instead of double ones? Trying to follow the instructions to add the Particle SDK is quite frustrating; the instructions in the docs say, “simply add the following line [pod “Spark-SDK” ] to your Podfile on main project folder:” It’s not clear from that statement if that’s the only thing that should be in the file. I was following more detailed instructions from a 2015 post (here). In that post @ido stated that pod “Spark-SDK” should be the only line in the file, and the OP also stated that in his summary; those instructions appeared to have worked at that time, so I’m guessing that something has changed since then.
