SwiftLee Weekly

You can get ready for iOS 17.

Hopefully, this does not catch you by surprise. We're close to September, meaning we're about to expect the Release Candidate of Xcode.

At WeTransfer, we started preparing for iOS 17 early on by maintaining a specific Xcode 15 branch. We kept it updated with our development branch and tested newly developed features for every new beta release.

From our experience, new bugs and fixes are still required for every beta update. Yet, I'm confident you'll be able to finalize your app for this next major release once the release candidate of Xcode becomes available.

My spare time focus is slowly shifting towards preparing a talk on Macros that I'll perform at several conferences in Q3 and Q4. I'm also excited about bringing this with me.

Stay tuned for more info, and enjoy this week's SwiftLee Weekly!
