react-native-maps: Error on startup on react-native 0.74 Bridgeless New Architecture

@mym0404 sure!

1. I enabled a feature of Xcode breakpoints which is Exception Breakpoints

1. I run the app and see that the constantsToExport was raising an exception. At this point, I had few ways to go:

• I tried to replace the [GMSServices openSourceLicenseInfo]; line with an empty string => no crashes and no redboxes
• I wrapped the [GMSService openSourceLicenseInfo]; in a try-catch block to see the exception

@try {
    license = [GMSServices openSourceLicenseInfo];
  } @catch (NSException *ex) {
    NSLog(@"[GMSServices openSourceLicenseInfo] threw and exception: %@",  ex);
  }

@matt-dalton @mrousavy let’s move the MMKV discussion to the MMKV repo, so we can close this issue for maps.

Hey - I’m seeing the same issue with react-native-mmkv, not sure what exactly is causing this.

Sorry for missleading @mHvNG I meant to put there these 3 lines.

rn_maps_path = '../node_modules/react-native-maps'
pod 'react-native-google-maps', :path => rn_maps_path
pod 'react-native-maps', :path => rn_maps_path

But now I saw that it doesn’t change anything. And you are right, there’s a crash. Deleting code from appDelegate helped me because I turned off new arch which you are turning on with pod install command.

Unfortunately I don’t know how to fix it or if we are even able to do it. Maybe @brentvatne or @lukmccall are able to help here?

Edit: It’s happening on clean rn 0.74 project with turned on new arch, so it’s quite easy to reproduce

@mateki0 Sadly I don’t have those booleans… My AppDelegate.mm:

#import "AppDelegate.h"
//#import <GoogleMaps/GoogleMaps.h>

#import <React/RCTBundleURLProvider.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//  [GMSServices provideAPIKey:@"API_KEY"]; // add this line using the api key obtained from Google Console
  
  self.moduleName = @"AppName";
  // You can add your custom initial props in the dictionary below.
  // They will be passed down to the ViewController used by React Native.
  self.initialProps = @{};

  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

- (NSURL *)sourceURLForBridge:(RCTBridge *)bridge
{
  return [self bundleURL];
}

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

@end

It’s basically the generated AppDelegate.mm file from 0.74 plus the code for adding an API key for Google Maps.
