canOpenURL 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.

Thoughts on design, development, AI infrastructure, and building products.
Xcode 27 Drops Intel: What Stops and What Still Ships
Xcode 27 runs only on Apple silicon, still ships Universal apps back to macOS 12, and silently drops x86_64 from ARCHS_STANDARD at deployment target 27.0.
DevelopmentThe 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 PermissionKit, ageRatingCode, and RESCIND_CONSENT answer who approves, and what happens when approval is withdrawn.
DevelopmentXcode 27 Removes ld64 and Requires Unique Module Names
Xcode 27 removes the ld64 linker and requires unique Clang module names. Both fire on toolchain upgrade. An audit of seven projects and tested commands.
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.
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 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.
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.
DevelopmentDesign 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.
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: Issey Miyake, A Piece of Cloth
Issey Miyake insisted he made clothing, not fashion. His pleats, his single pieces of cloth, and his refusal of the seasonal cycle argue that technology serves life, not spectacle.
Design & CultureThe Mac App Store Won't Let Window Managers Exist. I Shipped One Anyway.
App Sandbox forbids the API every window tiler needs, and Apple said ship outside the store. 941 Tiles ships inside it: Apple's Shortcuts engine moves the windows.
