Recently I wanted to share the app development process I went through with Claude and the notes I took. Building on my previous Cursor post, this time I raised the bar a bit and brought up a product from scratch with Claude.

We had another very exciting WWDC, one focused on a $3500 headset.

"What's new" videolarını izlemeyin, bloglardan faydalanın.2. Alanınız değilse "Deep Dive" videoları atlayın. Alanınızsa asla kaçır...
