i'm trying add information image files when user takes picture in ios. there way add more key/value pairs image's metadata? i've been looking imageio framework, seems constant. example in objective-c editing pre-existing properties: is possible add own metadata in captured images in swift. , swift example allows user read metadata stored in image: ios 8 photos framework. access photo metadata.
is adding new information .jpeg images possible? , if so, example in swift?
