I stumbled across this site when looking for information on how to process and optimise images with Swift. Coming from web development, ImageMagick was my go-to but I was curious about what tools might be provided by Apple.
Artur's post about using the Metal API to smoothly render images was like a whole new world!
His entire website is crafted with care. The tutorials are clear, the images beautiful and the whole thing is pleasant to read. I love functional programming, so his recent series about RxSwift has been interesting reading and a good counter to the reams (relatively speaking) that is written about Combine.
