To build an iPhone app that would make Steve Jobs weep with joy, you should focus on leveraging Apple's native SDKs and tools, as they provide the best performance and integration with Apple's hardware and software. Here are some key points and sessions from WWDC that can guide you:

1. Use Swift and SwiftUI: SwiftUI is highlighted as the best way to build apps for any Apple device. It allows you to describe the UI you want, and it takes care of details like dark mode, dynamic type, and tracking changes in your model. This makes your app more expressive and productive.
