React Native developer Menu not loading

Question

Developer menu in ios simulator will not launch with either cmd + D or cmd + ctrl + z

• things i've checked (in no order) :

  • cmd + r works properly
  • myApp and myAppTests schemes are set to debug mode
  • Slow Animations is off
  • Hardware > Keyboard > Connect Hardware Keyboard is on
  • watchman 4.7.0 is installed with brew install watchman (--HEAD needed libtoolize, in which brew changed to glibtoolize, therefore ./autogen couldn't find it )
  • Cleaned out Derived Data folder
  • Created new scheme for target
  • Upgraded XCode to 8.2.1 -> 8.3.1
  • react-native start --clear-cache starts successfully, react-native run-ios builds successfully

• Other Issues

  • nw_connection_get_connected_socket_block_invoke 1262 Connection has no connected handler run indefinitely
  • react-native run-ios outputs

  Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/zelosApp.app/Info.plist Print: Entry, ":CFBundleIdentifier", Does Not ExistCommand failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/zelosApp.app/Info.plist Print: Entry, ":CFBundleIdentifier", Does Not Exist

• Versions

  • react-native = "^0.43.3"
  • watchman = "4.7.0"
  • xcode = "8.3.1"

Any tips / questions would be greatly appreciated!

This happens to me too once in a while, and I have not been able to figure out why. However, one workaround is to select Device -> Shake in the simulator menu.
