Suddenly everything at https://github.com/Estimote/iOS-SDK has changed very much. Now example file but no old file. Why this big change with no warning?? very confusing.
Only examples were changed, no SDK was changed.
Now demos are much better and developer friendly. Just open one project and you can start playing with beacons. Previous demos were very cumberstone without much comment.
By no means this is a big change, just code samples were changed so it is easier for developers to pick it up.
