所以我试图在本机模块中实现 Garmin iOS SDK，以将 Garmin 手表连接到我的 react 本机应用程序。我已经完成了文档所说的创建本机模块的所有内容，并且能够初始化并开始扫描（这不会引发任何错误，并且会提示用户启用蓝牙，因此它肯定在做某事）。但是我必须实现的类的方法说 didScanDevice 没有被调用。再次，没有抛出任何错误。

我的问题是，本机模块是否存在一些问题，不允许我的实现 Garmin SDK 的类正确执行。

Native模块实现如下：

//AppDelegate.m
#import "AppDelegate.h"
#import <companion/companion.h>
#import <React/RCTBridge.h>
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  
  RCTBridge *bridge = [[RCTBridge alloc] initWithDelegate:self launchOptions:launchOptions];
  RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge
                                                   moduleName:@"swc"
                                            initialProperties:nil];

  if (@available(iOS 13.0, *)) {
      rootView.backgroundColor = [UIColor systemBackgroundColor];
  } else {
      rootView.backgroundColor = [UIColor whiteColor];
  }
  
  GHInitializer *initializer = [GHInitializer sharedManager];
  [initializer initializeLicense:@"SDK_KEY"];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  return YES;
}

- (NSURL *)sourceURLForBridge:(RCTBridge *)bridge
{
#if DEBUG
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
#else
  return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
#endif
}

@end

所以我终于解决了，最后我意识到 Garmin 模块必须在主线程上运行（不完全确定为什么会这样，但由于模块是私有的，我只能看到每个模块的接口我不是期待获得更多信息）。

一旦我告诉 react native 在主线程上运行我的模块，它就开始正常工作了。
