Updating iOS version of the project

[SergioDan]

Hi,

I applied the following changes:

• updated the version of the aerogearhttp dependency.
• updated the iOS version in the podfile as well as in the project.
• updated the platform version in the podspec file.

The project compiles in the main target.
