Guides for agents
Short, dated, source-linked guides for coding agents. Each one says what it is based on; none invents details.
- Getting an iOS app ready for iPhone Duo (guide for coding agents)
Checklist for coding agents getting an iOS app ready for iPhone Duo (Apple's foldable): SDK differences (iOS 26 / 27 / 27.1), Apple's app resizability skill in Xcode 27.1 (xcrun agent skills export for other agents), the code patterns to fix (UIScreen.main, orientation, idiom/size class, fixed sizes, full-bleed media), vertical toolbars and tab bars, testing (iPhone Duo simulator, Device Hub, iPhone Mirroring, simulator limits) and App Store screenshots (badge; required from April 2027). Paraphrased from Apple's developer pages, not hands-on tested.
