Swift Online weather forecast case tutorial

After a week of preparation, the swift online weather forecast video tutorial met with you. This set of video cases requires a certain language base learner.

Knowledge points involve many aspects.

For example: Swift location location corelocation, how Swift calls OC components, installation of afnetworking, etc. also involve Mac System terminal command line operations.

The implementation is simple, but the knowledge points use a lot, such as search location and so on.
