The camera app in iOS adds metdata such as the geolocation to your images, but adding this metadata to images in your own camera or imagee editing app is not exactly straightforward.
While working on his own image app Gustavo became frustrated at the lack of detailed documentation on how to add metadata to your own images and decided to create his own tutorial. After figuring things out Gustava decided to provide an open source library allowing you to easily do so yourself.
You can read Gustavo’s tutorial on his website here:

You can find the Github for the image metadata classes here:
