React Native Sending Events to JavaScript in Swift

Question

How can I send event\'s to JavaScript in Swift?

There is examples of Objc code how to send event to JavaScript, but I need to do in swift?

Answer 1

It is insane. How to pass anything as an event to Javascript, if this event is generated by Swift?

I am stuck with the same issue here: "Subclass RCTEventEmitter instead" The following does not work anymore.

self.bridge.eventDispatcher.sendAppEventWithName( eventName, body: "Woot!" )

I tried:

var emitter: RCTEventEmitter = RCTEventEmitter()

Instead of:

var bridge: RCTBridge!

Conesquently:

self.emitter.sendEvent(withName: eventName, body: "Woot!")

Instead of

self.bridge.eventDispatcher.sendAppEventWithName( eventName, body: "Woot!" )

From bad to worst, I go from a warning to the following hard error:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error when sending event: Location with body: woot. Bridge is not set. This is probably because you've explicitly synthesized the bridge in RCTEventEmitter, even though it's inherited from RCTEventEmitter.'

The documentation is very poor and old. It looks that not many people is using this hot garbage. Very frustrating.

This is an old implementation and it no longer works:

Another article, not very useful:

Very thorough and complex implementation, no one knows if it still works. In my case it doesn't, I get the same error above:

Then there are several objective-c swift cocktails, which I cannot drink at my age:
