Upgrading version

Upgrade from 0.59.9 to 0.63.3 manually following the React Native upgrade helper

Description

After a successful build either through Xcode or "react-native run ios" with no errors showing metro launches but a device is not detected while the simulator installs my app, shows the LaunchScreen then dead with a black screen.

"warn: No apps connected. Sending "reload" to all React Native apps failed. Make sure your app is running int the simulator or on a phone connected via USB."
