Swift/Objective-C iOS Developer

I need help pushing a set of existing iPhone apps to the next level. The codebase is mostly Swift with a few legacy Objective-C modules, and I want someone who can move comfortably between the two while keeping everything clean, testable and fast.

Here’s what the work looks like day to day: you’ll take screens from our designer, build adaptive layouts in Xcode, hook them to our REST-based backend, and drive the feature all the way through TestFlight. Along the way you’ll profile performance, fix any regressions you uncover, and make sure the release runs flawlessly on current devices. I expect disciplined Git usage, succinct pull-request notes, and an eye for modern iOS architecture patterns—MVC, MVVM or VIPER when it makes sense.

Deliverables for each feature cycle
• Implement the ticket in a separate branch with clear, well-named commits
• Unit and UI tests covering the new code (≈80 % coverage)
• Profiling report showing memory and frame-rate stability on real hardware
• TestFlight build ready for stakeholder review and App Store submission files prepared

If you’ve solved tricky performance bugs, integrated Core Data or slick animations, or kept an app up to date with the latest Swift/Xcode changes, tell me about it when you apply and include links to anything live on the App Store. Let’s build something great together.
