Notes from the studio.
Build logs, product launches and what we're learning — from CS50 problem sets to shipping apps.
iOS 27 rebuilds Siri around modern AI, makes Liquid Glass far easier to read and speeds up older iPhones. It makes Apple competitive again, but not the leader.
The iPhone 18 Pro and Pro Max look familiar, but a real variable-aperture camera, a 2nm chip and better cooling make them Apple's most serious normal iPhones yet.
Apple's first foldable costs £1,999, arrives years after Samsung's, and early hands-on reports say it feels more finished than it has any right to.
