Last month, I shipped a feature in three hours that would have taken me two days before. Did I close my laptop early? No. I just picked up the next task from the backlog.
Everyone online is talking about productivity. A thousand prompts that will change your life. How AI rewrote someone's workflow. How what used to take two days now takes two hours. It's everywhere, and it's loud.
I want to ask one simple question: Are you actually working less?

Hey folks!
I'm a Principal iOS Engineer working at a Fortune 100 company, with 10 years of experience building real products in production. But despite the title, I still write code daily, mentor teammates, and actively explore new tools and architectural patterns.
To stay sharp and give back to the community, I recently launched The iOS Weekly Brief - a free newsletter for developers who want signal, not noise.
Each Friday, I share:
• The most relevant Apple developer updates (not just iOS)
• Carefully selected articles I actually read and find valuable
• A tool or library I've tested or bookmarked
It's not AI-generated, not recycled - just top-notch content I'd want to read myself. No fluff. Just the good stuff.
Here is the link to my first weekly brief:
