React Native App throwing domain=FBSOpenApplicationServiceErrorDomain, code=3 Error

Question

I've updated quite a few NPM packages in my React Native app and now even though it seems to build fine, it starts and immediately crashes on the iOS simulator. The error that it throws is:

Failed to launch the app on simulator, An error was encountered processing the command (domain=FBSOpenApplicationServiceErrorDomain, code=3) The request to open "org.reactjs.native.example.myappname" failed. THe process did launch, but has since exited or crashed.

Prior to these npm package updates, the app was running fine. I found a few suggestions such as running rm -rf ios/build, cleaning the project, etc. I tried all these but still getting the same error.

Any suggestions on how to fix this issue? BTW, this is a react-native: "^0.65.1" app and the Xcode version is 12.4.

Answer 1

If there is no recent change in the iOS project files then try:

1. Reset Content and Settings of the simulator:

2. If reseting the simulator content and settings doesn't work, update Xcode to its latest version.
