SDK41 expo-splash-screen patch failing on iOS

Hey there,

back in SDK40 I patched expo-splash-screen to hide the app’s content from the AppSwitcher when the app goes to background. This worked fine until I upgraded to SDK41. Now I’m getting the following error:

NSInvalidArgumentException (RNSScreen)
-[EXSplashScreenService forceShowSplashScreenFor:]: unrecognized selector sent to instance 0x600000d24310

The error is thrown in applicationDidEnterBackground, it doesn’t even enter the forceShowSplashScreenFor function. I’m not an iOS developer - any idea what I’m missing here?

and the patch for expo-splash-screen to add the forceShowSplashScreenFor function:
