objc.io was founded 2013 in Berlin by Chris Eidhof, Daniel Eggert, and Florian Kugler. We started objc.io to create a platform for in-depth technical topics relevant to all iOS and macOS developers.

From June 2013 to May 2015 we published 24 monthly issues, containing 125 articles written by 67 authors. We're very humbled by the feedback of the community and the huge effort put in by all the contributors.

After two years of publishing an issue every month, we decided to take a break and to focus on some more long-form writing. We published our first book -- Functional Swift -- in late 2014. In 2015 we published two new books: Advanced Swift and Core Data.

In June 2016 we returned to publishing regular online content with our Swift Talk series. We publish in-depth videos every week, in which we showcase and discuss solutions to problems we encounter while building projects in Swift.

In June 2017 we published Optimizing Collections — our first book written by an external author, Károly Lőrentey. In early 2018 we published App Architecture, which we co-authored with Matt Gallagher. Finally, we published our latest book Thinking in SwiftUI in the spring of 2020.

Next to our regular publishing of articles, books, and videos, we also teach workshops, focusing on advanced Swift and SwiftUI topics.
