THIS WEEK'S BLOG POST

The 7 changes I do for every new Xcode project

I bet you recognize: you start a new project, and you immediately apply a few changes. It's at least what I like to do and I decided to capture that process and share it with you.

WHAT I'M WORKING ON

300 newsletter issues!

I can't send you this newsletter without highlighting this incredible milestone.

300 newsletter issues, 300 weeks of keeping Swift developers up to date. It’s crazy to realize I’ve been doing this since March 2020!

It all started small, with just a few subscribers. The email was far from high-quality, but it did deliver the weekly new article I already published every week.

Slowly but surely, the newsletter subscribers count grew towards 30K+ today. Numbers are often hard to really value, but imagine 30,000 iOS developers standing in front of you every week, waiting for you to say:

  • These articles from the community are a must-read this week
  • The Swift team changed these evolution proposals
  • I worked on this and here are my learnings

Let's celebrate — Share & Win AirPods Pro 3

To celebrate this milestone, I'd love to run an exclusive giveaway for you as a subscriber. Anyone that invites at least 1 subscriber will have a chance of winning the latest AirPods Pro 3.

Here's how you can join:

  1. Copy your unique referral link [RH_REFLINK GOES HERE]
  2. Get at least 1 new subscriber to join the giveaway

To make it easy, you can use these links to share quickly on X/Twitter, LinkedIn, Bluesky. However, your personal story of why you subscribe will likely do better!

Next week, I'll announce the lucky winner, but even if you don't join: thanks for being a SwiftLee Weekly subscriber. I look forward to sending many more issues!
