Thoughts on design, development, AI infrastructure, and building products.
The Consent Lifecycle: What Ships After the Age Check
Declared Age Range answers how old. PermissionKit, ageRatingCode, and RESCIND_CONSENT answer who approves, and what happens when approval is withdrawn.
DevelopmentcanOpenURL Is Deprecated: What to Call Instead
Apple deprecated canOpenURL in three sentences, and halved the scheme allowlist ceiling to 25 entries. The replacement, and the one check it cannot do.
DevelopmentXcode 27 Drops Intel: What Stops and What Still Ships

DevelopmentOn Demand Resources Is Deprecated: What Background Assets Costs
Apple deprecated ODR in 13 words. The replacement forks three ways, sets an iOS 26 floor, and hands you back the disk management the system used to do.
DevelopmentThe iOS 27 Launch Screen Rule: Four Keys or Rejection
Apps built with the iOS 27 SDK must declare a launch screen or the App Store rejects them. The four keys, and how to audit a target with a generated plist.
DevelopmentThe @State Macro: What Xcode 27 Stops Compiling
Xcode 27 reimplements SwiftUI's @State as a Swift macro. The break lands on toolchain upgrade, not deployment target, and two patterns stop compiling.
DevelopmentThe App Store's Social Media Checkbox and What It Costs
September's App Store rule makes every submission declare social media capabilities. The under-13 carve-out costs an entitlement, an API, and a branch.
DevelopmentDesign Philosophy: Issey Miyake, A Piece of Cloth

Design & CultureDesign Philosophy: Rei Kawakubo, Start From Zero
Rei Kawakubo built Comme des Garçons on a refusal: no explanation, no precedent, no finished meaning. Her in-between -- mu and ma -- treats the void as material.
Design & CultureDesign Philosophy: Renzo Piano, Piece by Piece
Renzo Piano calls architecture 'a socially dangerous art' because nobody can look away from a bad building. His answer: the workshop, lightness, and building piece by piece.
Design & CultureDesign Philosophy: Norman Foster, The Optimist's Machine
Norman Foster built the case that technology is how architecture cares for people: ecological skyscrapers, a glass dome the public walks above parliament, and an airport that reads as calm.
