React-native get stuck at Dependency Graph

The building of the dependency graph may take some time (ca 1-3 minutes). The progress is shown by a percentage behind this line; if the percentage disappears you are ready. The react-native start command doesn't terminate, as it continues to serve the transformed source code with the react native packager. Your app will make requests to the provided url if you have the default settings.

One reason the "Building Dependency Graph" step might hang may be due to that there is a (Chrome) debugger session running from a previous session or another project. One way to fix that is to completely quit out of Xcode, your terminal, and Chrome and then restart everything. I'm sure there is a better way to fix the issue, but that is what worked for me.

I had the same problem, that it ended there and even refreshing the simulator didn't make the packager to go on. Then I figured it out: I was still connected to the Internet via a VPN, so the simulator couldn't connect to the packager. Simply closing the VPN solved the issue.
