I was working through this tutorial, however when I used the react native cli to generate a new project, it would not be able to launch ( with react-native run-ios). I kept getting the above error and I've tried troubleshooting for hours, I think it might be a problem with Xcode as I recently updated it but I'm not sure. Here is the full error message:

Installing build/Build/Products/Debug-iphonesimulator/auth.app An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2): Failed to install the requested application An application bundle was not found at the provided path. Provide a valid path to the desired application bundle. Print: Entry, ":CFBundleIdentifier", Does Not Exist Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/auth.app/Info.plist Print: Entry, ":CFBundleIdentifier", Does Not Exist

If anyone has encountered this problem and fixed it please let me know what works for you! This has put me at a complete standstill and I would greatly appreciate any help. Could this be a versions issue that react native has not caught up with yet? Thanks!

There is something wrong with react-native init

Please do not initialize the project with react-native init ProjectName

You should append react-native version argument in the end.

For example:

react-native init ProjectName --version 0.44.2

If you are using XCode 10 try downgrading to XCode 9.4.1, by downloading and installing this version in official apple portal.

There might be a lot of possibilities of how to fix it, most of them are clearing npm cache, uninstalling node_modules, deleting ios and android folder and rebuilding, so you should try all of them. But downgrading XCode is what helped me after 5 hours at it

Good luck, don't be discouraged with this error, eventually you will find out the solution!
