18 obj-c examples migrated (1308/1311-1317/1319/1320/1321/1341-1347): import
runtime classes '#foreign #objc_class("X") {' → '#objc_class("X") extern {'
(prefix→postfix) + fn/comment '#foreign'→'extern'. No 13xx snapshot asserts on
'foreign' text → all behavior-preserving; empty snapshot diff, corpus-validated.
Per the keep-list policy: KEPT identity-#foreign tests 1306/1318 (filename
ffi-*-foreign*); LEFT comment-only #foreign in the extern/export test files
1332/1348/1349 (no decls). Bare defined #objc_class examples (no #foreign) untouched
— not a purge target. Suite green (647 corpus / 444 unit, 0 failed).

// Phase 3 step 3.0 (PLAN-FFI.md): `inst.method(args)` on an
|
|
// `#objc_class`-typed receiver lowers to `objc_msg_send` with a derived
|
|
// selector. This test covers the niladic shape: the sx-side method name
|
|
// is used verbatim as the selector (`length` → `length`).
|
|
//
|
|
// Test pattern mirrors `ffi-objc-call-08-multi-keyword.sx`: synthesize a
|
|
// fresh class at runtime via `objc_allocateClassPair` + `class_addMethod`,
|
|
// declare the sx-side `#objc_class` against the same name, then invoke
|
|
// the DSL form. On macOS this exercises the real Obj-C runtime; on
|
|
// other platforms the test skips.
|
|
//
|
|
// Pre-3.0: the dispatch bails at lower.zig with "method calls on
|
|
// 'objc_class' runtime not yet supported (Phase 3/4)". Snapshot captures
|
|
// that diagnostic.
