Step 2:

1. Open Project in Xcode
2. Run (Error In Signing)
3. Sign the project [to fix the Xcode Error]
4. Run Again (Running Metro Bundler on port 8081. terminal window appears + Build Succeed)
5. App Launches With Error [Red Screen]

Questions

1. Why I can’t run the project without signing?
2. Why this error Appears? & How to solve it?

Thanks

In terminal perform, react-native start --reset-cache and then react-native run-ios or react-native run-android in new terminal window works for me.
