Migrating my SwiftUI App to VisionOS in 2 Hours

How I migrated my SwiftUI app CrossCraft to support visionOS for the Day 1 Release of the Apple Vision Pro. It took effectively about 2 hours in total, this article summarizes my key learnings along the way.

Just a few months ago, I released CrossCraft: Custom Crosswords, an app written entirely in SwiftUI and available on iOS, iPadOS, and macOS. For the launch of the Vision Pro, I set myself a challenge to migrate it to the new visionOS platform — but I started the migration just 3 days before launch day!

So the question was if I would be able to pull it off in this short amount of time. But luckily it turned out to be easy enough, so my app was ready on Day 1! 👇
