react-native-gesture-handler: RNGestureHandlerManager.h:9:52: error: expected a type - eventDispatcher:(nonnull RCTEventDispatcher *)eventDispatcher;

Description

Cannot build iOS app after upgrading from RN version 0.63.2 to 0.65.0-rc.3. I am getting this error:

In file included from /Users/…/ReactNativeProjects/…/node_modules/react-native-gesture-handler/ios/RNGestureHandlerManager.m:1: /Users/…/ReactNativeProjects/…/node_modules/react-native-gesture-handler/ios/RNGestureHandlerManager.h:9:52: error: expected a type eventDispatcher:(nonnull RCTEventDispatcher *)eventDispatcher;

Problem is in RNGestureHandlerManager.h, on the line below:

- (nonnull instancetype)initWithUIManager:(nonnull RCTUIManager *)uiManager
                          eventDispatcher:(nonnull RCTEventDispatcher *)eventDispatcher;

Edit: When I upgrade to RNGestureHandler version 1.10.3 I get the errors below: Screen Shot 2021-08-11 at 22 00 54

#import <React/RCTEventDispatcher.h> solved for me

To Solve:

yarn upgrade react-native-gesture-handler
cd ios
pod install

Most likely you installed react-native-gesture-handler with react-navigation so it’s using an older version unsupported by RN update.

@LBojanic - where did you make that change?

At the top of the same file. in RNGestureHandlerManager.h

If I’m not wrong, I’ll have to do this every time I have a clean build right ? Could you please tell me what the permanent solution to this issue is ? I’m facing this after upgrading from 0.63.3 to 0.64.2. My gesture handler version is 1.6.0

@aditya-keri-betterhalf look at this file https://github.com/software-mansion/react-native-gesture-handler/blob/master/ios/RNGestureHandlerManager.h it has @class RCTEventDispatcher; so you upgrading should fix it but if you are using any other libraries that requires a specific version of gesture handler that upgrading will not work.

I am experiencing the same issue. Tried to remove pods and cleaning the build folder - didn’t help. Also tried upgrading package with no succes
