Flipper is a 'work in progress' and issues may occur. This page contains known issues associated with the iOS platform and provides steps you can take to try to resolve them.
You'll need to manually add this ViewController to your app to see the in-app diagnostics.
iOS device not showing up
Make sure idb is installed and configured in the Flipper settings.
iOS simulator device not showing up
Ensure that your simulator is on the same version as selected in
xcode-select. You can do that by checking that commands
ps aux | grep CoreSimulator and
xcode-select -p shows the same Xcode version. If not, update the xcode version by sudo
xcode-select --switch <Path to xcode>
iOS app connection error "Connection failed. Failed to find device..."
If during connecting iOS app to Flipper you see error message "Connection failed. Failed to find device <device_id> while trying to connect app" - try executing
idb kill on a terminal and restarting Flipper as workaround to reset idb state.
