Issue !TARGET_OS_TV React Native, cannot compile to iOS, and i have remove this code to make it works.

[primayudantra]

I got this error :
react-native/React/Profiler/RCTProfile.m:386:57: Incompatible block pointer types assigning to 'UIActivityViewControllerCompletionWithItemsHandler _Nullable' (aka 'void (^)(NSString * _Nullable __strong, BOOL, NSArray * _Nullable __strong, NSError * _Nullable __strong)') from 'int ((^)(void))'

when i compiled with XCODE i got this error and i must remove this code.

#if !TARGET_OS_TV
      UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[[NSURL fileURLWithPath:outFile]]
                                                                                           applicationActivities:nil];
      activityViewController.completionWithItemsHandler = ^(__unused UIActivityType activityType,
                                                            __unused BOOL completed,
                                                            __unused NSArray *items,
                                                            __unused NSError *error) {
        RCTProfileControlsWindow.hidden = NO;
      };
      RCTProfileControlsWindow.hidden = YES;
      dispatch_async(dispatch_get_main_queue(), ^{
        [[[[[UIApplication sharedApplication] delegate] window] rootViewController] presentViewController:activityViewController
                                                                                                 animated:YES
                                                                                               completion:nil];
      });

#endif

This issue looks like a question that would be best asked on StackOverflow.

I don't believe that this is an issue with his system alone. I too was receiving the same error today when attempting to run. @primayudantra Were you ever able to figure this out?

@hramos the issue is within the react native source code as can be seen from the source file path "react-native/React/Profiler/RCTProfile.m" . I too faced this issue.

After digging bit deeper, it seems in RN version 0.42.0 a change was made at the exact same location where this issue is occurring. Here is the commit for your reference. GitHub commit. Moreover this started occurring only after upgrading to version 0.42.0.

As @primayudantra mentioned , after commenting out the said code, the Xcode project complied and ran properly, however changing the source files of RN is definitely not a solution here.

Also i do understand that this issue has been closed, but since many people are facing this issue, I wanted to share my view here. @hramos we would appreciate any inputs from your side.
