No Bundle URL Present is a common react native error you come across when you try to run your react native project on iOS device or iOS simulator. There are some solutions for this specific react native issue and the following solution worked for me:
Keep the iOS simulator running and also keep the metro bundler open. Now again go to the project folder, open the terminal and run react-native run-ios. The react native issue will be resolved.
Still have the same problem? Then have a look at the react native issue on githuband try other solutions given there.
