Swift 编译器对 ObjC API 自动应用名称简化规则（Swift 3+ SE-0044）， 即使是 1.x 老 SDK header 也会被简化。ObjC selector 不变，运行时 仍调 +[WXApi getApiVersion] / +[WXApi sendReq:]，但 Swift 端必须 写简化后的名字： - ObjC +(NSString *)getApiVersion → Swift WXApi.getVersion() - ObjC +(BOOL)sendReq:(BaseReq*)req → Swift WXApi.send(_:) 错误信息里 Swift 编译器明确给出："has been renamed to 'getVersion()'" + "obsoleted in Swift 3"。 注释里同步说明 selector 与 Swift 名映射关系，避免未来维护者误以为 我们调到的是 2.x SDK 的 getVersion（实际仍是 1.8.2 的 getApiVersion）。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
