I'm a seasoned iOS developer specializing in SwiftUI. I build prototypes and MVPs that help startups and product teams move faster and launch smarter.
With iOS 26 now in beta and launching this fall, I decided to revisit how I build onboarding flows in SwiftUI. Like many indie developers, I typically support the latest iOS version along with the one before it. This allows me to take advantage of the modern features introduced in iOS 18 while also preparing for the new capabilities coming in iOS 26.
This post introduces a demo project that shows how to build a responsive, SwiftUI-based workout feed using HealthKit. The project is designed for iOS developers who want to display large sets of workout data, including route visualizations, while keeping the interface fast and efficient.
I've been working on a small project to automate a newsletter using AI. The goal is to make something useful for people like me—solopreneurs or small teams who want to share good content without spending hours on it.

Whether I used the Strava app on my Apple Watch or tracked it with my Garmin Edge 130 Plus, my workouts simply didn't show up properly in the Fitness app. It quickly became clear that some companies choose not to send…
When the Apple Watch first came out, I was immediately impressed by the Activity rings. They were a simple but genius way to make sure people stayed active, and I still believe they're effective for promoting general fitness. For the average person, closing those rings each day can be a great way to stay on track. After all, staying active is one of the most important factors for maintaining good…
Lately, every time I see a job opening for iOS development it's either React Native, Flutter, or some type of cross-platform stack. I admit that these technologies make sense in many cases. Learning React Native has crossed my mind a few times. I'm choosing to stick with native development using Swift and SwiftUI.
