Taken from the answers at Got "is not a recognized Objective-C method" when bridging Swift to React-Native; the fact that it doesn't work, is because of the difference in the first argument labels.

To make it work with your initial code you should write the first argument of your Swift to be without a name, like this:

@objc
func loginWithEmail(_ resolve: RCTPromiseResolveBlock, rejecter reject: RCTPromiseRejectBlock) -> Void {
    //   the trick  ^
    resolve("This method is no longer troublesome")
}
