如何迁移到Xcode12.5

我无法使用 Xcode 12.5 构建使用 Xcode 11 正确构建的 React Native 项目。

我不能再使用 Xcode 11,因为只有更新的 Xcode 版本才带有必要的 API 来发布/上传到 TestFlight 和应用商店。

现在我收到三个构建错误:

Cannot initialize a parameter of type 'NSArray<id<RCTBridgeModule>> *' with an rvalue of type 'NSArray<Class> *'

Cannot initialize a parameter of type 'NSArray<id<RCTBridgeModule>> *' with an rvalue of type 'NSArray<Class> *'

Cannot initialize a parameter of type 'NSArray<id<RCTBridgeModule>> *' with an rvalue of type 'NSArray<Class> *'

我还注意到部署目标从 10 和 9 自动升级:

- IPHONEOS_DEPLOYMENT_TARGET = 9.0;
+ IPHONEOS_DEPLOYMENT_TARGET = 12.1;

添加了一些与 Clang 相关的新属性:

+ CLANG_ANALYZER_LOCALIZABILITY_NONLOCALIZED = YES;

如何配置项目以使用 Xcode 12.5 部署此应用程序?

我通过更改 React 模块 RCTCxxBridge.mm 中的参数来解决这个问题,如下所示:

- (NSArray<RCTModuleData *> *)_initializeModules:(NSArray<id<RCTBridgeModule>> *)modules
                               withDispatchGroup:(dispatch_group_t)dispatchGroup
                                lazilyDiscovered:(BOOL)lazilyDiscovered

到:

- (NSArray<RCTModuleData *> *)_initializeModules:(NSArray<Class> *)modules
                               withDispatchGroup:(dispatch_group_t)dispatchGroup
                                lazilyDiscovered:(BOOL)lazilyDiscovered

我正在运行 0.59 并且没有使用 CocoaPods,但基本的修复是以下形式的转换:

NSArray<id<RCTBridgeModule>> *)modules

应替换为:

NSArray<Class> *)modules

  • I had edited my above response to be I belive the fix, rather than saying I had the same issue with Xcode 12.5.
  • @haleonj, please refer to this https://github.com/facebook/react-native/issues/28405#issuecomment-827424477. You have to change RCTBridgeModuleNameForClass(module)) to RCTBridgeModuleNameForClass(Class(module))) as well
  • Can you add "You have to change RCTBridgeModuleNameForClass(module)) to RCTBridgeModuleNameForClass(Class(module))) as well" please? I want to mark the answer once it's complete.
  • After using this fix all the old errors are removed but one error manifests, `NSArray<id<RCTBridgeModule>>`, on line 300 of `RCTTurboModuleManager.mm`.

回答

这个对我有用。

  1. 打开RCTCxxBridge.mm(第 770 行)并将参数类型从:更改(NSArray<id<RCTBridgeModule>> *)modules(NSArray<Class> *)modules
  2. 打开RCTTurboModuleManager.mm(第 300 行)并从:更改
    RCTBridgeModuleNameForClass(module))RCTBridgeModuleNameForClass(Class(module)));

以上是如何迁移到Xcode12.5的全部内容。
