This API is very much a work in progress, but it allows you to authenticate to the servers, as well as request information about the player, inventory, etc.
This should be more than enough to get anyone going, especially since all of the protos are transpiled to Swift and are working.
Special thanks to https://github.com/tejado/pgoapi and https://github.com/AeonLucid/POGOProtos for making this possible.
You can install PGoApi with CocoaPods. It isn't fully published yet, but you can install it from git:
use_frameworks!
pod 'PGoApi', :git => 'https://github.com/lsapan/pgoapi-swift', :branch => 'master'
pod 'ProtocolBuffers-Swift', :git => 'https://github.com/alexeyxo/protobuf-swift', :branch => 'ProtoBuf3.0-Swift2.0'
Be sure to include ProtocolBuffers-Swift as shown above.
The API makes use of delegates, and a practical working example is in ExampleViewController.swift. It handles logging in, updating the API endpoint, etc.
To summarize, create an instance of PGoApiRequest and call whichever RPC commands you'd like to run (optionally with parameters). Once you've queued up the commands you'd like, call makeRequest to fire off the request and subrequests. Your delegate should implement didReceiveApiResponse and didReceiveApiError to handle the response (or lack thereof).
Updating the protos is a bit tricky, I'll add more information on that later. For now, the protos are fresh and should be good for awhile.
In short: please do! I threw this together in a few hours, but I'd love help in really fleshing it out.
getMapObjects is almost working but still needs a bit more. And there's lots of grunt work to do just adding all the possible requests to PGoApiRequest.
