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 ` ## 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 while trying to connect app" - try executing `idb kill` on a terminal and restarting Flipper as workaround to reset idb state.
