resize-auditor

Scans your app for resize readiness under the iOS 27 windowing model — where every window resizes, iPhone apps included — sweeping UIKit code, Info.plist, and the scene manifest for the assumptions that break (or block launch) when the canvas stops being fixed.

What It Does

• Detects launch-blocking configuration: app-delegate-only lifecycle (no scene delegate), which no longer launches when built against the iOS 27 SDK
• Finds deprecated geometry sources — UIScreen.main bounds/scale, UIRequiresFullScreen, orientation- and idiom-derived layout
• Flags cached window geometry and hardcoded device-size constants
• Checks rendering surfaces (Metal drawableSize, SpriteKit scale modes) for live-resize handling
• Checks iPhone Mirroring input compatibility (scroll-type masks, touch-type assumptions in custom gestures)
• Reasons about completeness: minimum window size, resize throttling, per-scene state restoration, multi-window opt-in
• Produces a Resize Readiness Score (RESIZE-READY / PARTIAL / FIXED-CANVAS)

How to Use

Natural language:

• "Audit my app for screen resizing support"
• "Is my app ready for resizable windows on iOS 27?"
• "Check whether my app will work in iPhone Mirroring"

Explicit command:

/axiom:audit resize
