Description

Recently upgraded to RN 0.58.3 (from 0.57.8) via react-native-git-upgrade. Everything compiles just fine.

However, invoking a debug run via react-native run-ios will result in an immediate error message:

Notes:

• Reloads (cmd-R) of a running app clear the error. (App runs as expected)
• Subsequent reloads (cmd-R) of already running app do not trigger the error. (App runs as expected)
• Closing either the simulator itself and restarting, OR closing the running app within the simulator session and relaunching will trigger the error once again.
• Each of the 0.58.0, 0.58.1, 0.58.2, 0.58.3 releases give the same results.

Reproducible Demo

In my case it was simply upgrading to RN 0.58.3 from 0.57.8 via react-native-git-upgrade then running react-native run-ios to encounter the error message.
