Xcode Archive Error: Undefined symbols for WorkletRuntime::runGuarded 🔧

[jenskuhrjorgensen]

How were you trying to build the app?

Hi

I've run into an Xcode archive issue when using react-native-vision-camera v2.16.5 together with the newest version of react-native-reanimated (3.6.1). The issue arises because react-native-reanimated introduced some branching behaviour in v3.6.0 which relies on the PRODUCTION flag used when installing pods. This means that you have to run PRODUCTION=1 pod install in order to be able to create iOS release builds. In v3.5.4 of react-native-reanimated it was enough to just run pod install before creating iOS release builds. This is an issue for us because we have pods committed to the repo so we cannot rely on two different sets on pods based on whether you need to create debug or release builds.

I've filed an issue with react-native-reanimated (https://github.com/software-mansion/react-native-reanimated/issues/5465) but thought this might be relevant for users of react-native-vision-camera since that combination was what broke it for me. And also I hope that someone in here can come up with a solution to make it work. I don't know if the issue exists with react-native-vision-camera v3, but we cannot use that yet because it doesn't work with JSC (and we cannot yet update to Hermes due to its excluded JS features).

The issue can be reproduced with the react-native-vision-camera example app when installing react-native-reanimated v3.6.1 and then making a call to WorkletRuntime::runGuarded e.g. like this:

#import "AppDelegate.h"

#import <React/RCTBundleURLProvider.h>
#import <RNReanimated/WorkletRuntime.h>

@implementation AppDelegate

std::shared_ptr<reanimated::WorkletRuntime> workletRuntime;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  self.moduleName = @"VisionCameraExample";
  // You can add your custom initial props in the dictionary below.
  // They will be passed down to the ViewController used by React Native.
  self.initialProps = @{};

  jsi::Runtime& runtime = *(jsi::Runtime*)"@123";
  jsi::Value value = jsi::Value(42);
  auto rt = reanimated::extractWorkletRuntime(runtime, value);
  jsi::Runtime &rtt = rt->getJSIRuntime();
  auto worklet = reanimated::extractShareableOrThrow<reanimated::ShareableWorklet>(rtt, value);
  workletRuntime = reanimated::extractWorkletRuntime(runtime, value.asObject(runtime));
  std::weak_ptr<reanimated::WorkletRuntime> weakWorkletRuntime = workletRuntime;
  auto workletRuntime = weakWorkletRuntime.lock();
  workletRuntime->runGuarded(worklet);

  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

- (NSURL *)sourceURLForBridge:(RCTBridge *)bridge
{
#if DEBUG
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index"];
#else
  return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
#endif
}

/// This method controls whether the `concurrentRoot`feature of React18 is turned on or off.
///
/// @see: https://reactjs.org/blog/2022/03/29/react-v18.html
/// @note: This requires to be rendering on Fabric (i.e. on the New Architecture).
/// @return: `true` if the `concurrentRoot` feature is enabled. Otherwise, it returns `false`.
- (BOOL)concurrentRootEnabled
{
  return true;
}

@end

and the finally archiving the app via Xcode (requires signing to be set up for the target).
