Apple announced one important — and immediate — upgrade at WWDC this week, the introduction of support for third-party large language models (LLM), such as ChatGPT from within Xcode. It’s a big step that should benefit developers, accelerating app development.

I recently wrote about how Apple’s lagging AI technology might impact its device and OS market share. But as I sat at the company’s headquarters in Cupertino and listened to the WWDC keynote, I came to the opposite conclusion.

Apple announced Liquid Glass on Monday for all of its devices at WWDC 2025. Perhaps the most noticeable thing about it is that app icons, tab bars, and even the text magnifier you’ll see when you hover over words feel, well, liquid-y and glassy.
