react-native-rn074-synthesize-issue

Demo for issue on RN 0.74.

This module contains a very simple code logging the bridge value:

@implementation Rn074SynthesizeIssue

@synthesize bridge = _bridge;
RCT_EXPORT_MODULE()

// Example method
// See // https://reactnative.dev/docs/native-modules-ios
RCT_EXPORT_METHOD(multiply:(double)a
                  b:(double)b
                  resolve:(RCTPromiseResolveBlock)resolve
                  reject:(RCTPromiseRejectBlock)reject)
{
    NSNumber *result = @(a * b);
    NSLog(@"Bridge is: %@", _bridge.description);

    resolve(result);
}
@end

When bridgeless mode is on, the bridge is null.

Setup

yarn
cd example
yarn
(cd ios && RCT_NEW_ARCH_ENABLED=1 pod install)

Reproducing the issue

Open the app on Xcode (cd example/ && xed ios), then run the app.

When the app launches, in the Xcode logs you should see:

Bridgeless mode is enabled
Running "example
Bridge is: (null)

When you turn bridgeless mode off by uncommenting the code in AppDelegate.mm, you get as expected:

Running "example
Bridge is: <RCTCxxBridge: 0x10540cb00>
