Watch Now: Why LLMs in Apple’s Xcode can’t write Swift Code

Why do ChatGPT, Claude, and other LLMs struggle with Swift and SwiftUI? In this video, we break down why Apple’s ecosystem is harder for AI to learn from limited public Swift code to Apple’s constant breaking changes. We discuss how most real-world Swift projects aren’t open-source, why AI often misses recent language updates, and what happened with Apple’s promised Swift Assist features.

We also cover why many iOS developers now use both VS Code and Xcode, and how Android and open-source ecosystems are moving faster because their code is easier for AI models to learn from.
