iOS job interviewers be like: “So you’re good with people, deliver on time, have a vast understanding of UIKit and the iOS platform, know both Objective-C and Swift, and you’ve tamed the beast called Xcode and code signing? Cool! Now do a binary sort please.”

Remember that teaser tweet from earlier? I'm ready to share the news! I quit my job and starting in July I'm off on my own. My plan is to focus more on my blog, books, and workshops, combined with contracting (got to pay those bills). Super excited about this new adventure 😱

In Xcode 14.0 Beta 2 Combine has received a super welcome update! They've added primary associated types to Publisher so now we can write "some Publisher<Output, Error>" instead of erasing to AnyPublisher! Learn more about primary associated types here: donnywals.com/what-are-prima…
