Mac Catalyst reports both os(iOS) and canImport(AppKit) as true, so the mismatched conditionals collided: PlatformTypes.swift selected the UIKit family (os()-based) while ~8 other files selected the AppKit branch (canImport(AppKit)-based), calling AppKit-only APIs on UIKit types and, for the paired +AppKit/+UIKit files and InlineHostingAttachment's twin #if blocks, compiling both branches at once into duplicate declarations. Replace every `#if canImport(AppKit)` with `#if os(macOS)` so the whole codebase gates on one axis: macOS => AppKit, everything else (incl. Catalyst) => UIKit. UIKit/#else branches are unchanged. Add a Build workflow that compiles the package for macOS, iOS, and Mac Catalyst so the fix stays green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
