16 fn/global examples across categories (0415/0602/0603/1024/1025/1605/1607-1609/ 1611/1616/1619/1622/1628/1635/1636): bare '#foreign'→'extern'. All cls=0 (no class forms). Marker'd ones (1605/1609/1611 + the rest) corpus-validated; the 3 unmarked uikit importers (1607/1608/1616) verified byte-identical via 'sx ir' probes. Empty snapshot diff; suite green (647 corpus / 444 unit, 0 failed). LEFT comment-only/provenance #foreign (0716/0729 + issues/0030-extern-global + extern-test files 1223-1231/1332/1348/1349/1426) and the keep-list (identity ffi-foreign-* + foreign-asserting diagnostics 1172/1174/1219/1228/1620) for Phase 8.

// Minimal iOS app entry point — pure sx, no .m files.

// 1. Register a class `SxAppDelegate : UIResponder <UIApplicationDelegate>`
|
|
// dynamically, with one method:
|
|
// application:didFinishLaunchingWithOptions: returns YES (BOOL 1).
|
|
// 2. Call UIApplicationMain(0, null, null, @"SxAppDelegate") to hand off to
|
|
// UIKit's run loop. This blocks until the app exits.
|
|
//
|
|
// After install + launch, the simulator shows the default black screen
|
|
// (UIWindow not created — that's 5.8) and the AppDelegate callback fires
|
|
// once at startup. The process stays alive because UIApplicationMain
|
|
// drives the iOS run loop.
