Flutter应用部署TestFlight后闪屏崩溃问题求助

问题 #

我已在多台iOS和Android设备上测试应用，从未遇到过问题，但昨日将应用部署至TestFlight后，出现闪屏崩溃情况。

我遇到的情况是：第一次崩溃时修复了对应包，但再次部署后，下一个使用.swift源文件而非仅.m和.h文件的包又引发崩溃。怀疑可能是Firebase问题，但配置看起来正确，希望获得解决该启动崩溃问题的思路。

解决思路 #

核心问题定位 #

从崩溃日志看，崩溃发生在connectivity_plus的Swift插件注册阶段，属于空指针访问（EXC_BAD_ACCESS），说明Swift运行时尝试访问空对象的类型信息。这类问题通常和Swift与OC桥接、代码签名、Swift库初始化顺序或第三方库兼容性有关。

具体排查步骤 #

• 检查iOS项目Swift基础配置

  1. 打开iOS目录下的Runner.xcworkspace，进入Runner target的Build Settings：
     • 确认Always Embed Swift Standard Libraries在Debug和Release模式下均设为YES
     • 确保Swift Language Version统一（推荐5.0及以上）
  2. 查看Frameworks, Libraries, and Embedded Content，所有含Swift代码的第三方库（如connectivity_plus、firebase_messaging）需设置为Embed & Sign

• 彻底清理缓存并重建项目
  执行以下命令清理所有缓存，避免旧构建文件干扰：
