How to bridge React Native Promise to Swift

Question

Hi fellow software enthousiasts,

I am currently working on a React native project for which I need to add some logic which has been written in swift. I am able to trigge

I did eventually come up with a solution. It is not exactly like React native people intended it I believe, but it works. So i can continue and maybe someone else is set on the right track with my solution. Although, please post the way it is supposed to be.

So I decided to start with the Objective-C way first. So I created a .h file for my module.

MyLoginBridge.h

#import 

@interface MyLoginBridge : NSObject 
@end

Then alter the .m file

#import "MyLoginBridge.h"
#import "MyProject-Swift.h" // Include the swift header manually

@implementation MyLoginBridge

RCT_EXPORT_MODULE(MyCustomLoginJSName);

RCT_EXPORT_METHOD(loginWithEmail:(RCTPromiseResolveBlock)resolve   rejecter:(RCTPromiseRejectBlock)reject)
{
    // Manually init the module and call swift function
    MyLoginModule* module = [[MyLoginModule alloc] init];
    [module loginWithEmailWithResolver:resolve rejecter:reject];
}

@end

The swift file and the bridging header remained the same. This works.
