このようなエラーがでてbrew xxxをしても解決しない場合

[!] iOS toolchain - develop for iOS devices (Xcode 10.2.1)
    ✗ Verify that all connected devices have been paired with this computer in Xcode.
      If all devices have been paired, libimobiledevice and ideviceinstaller may require updating.
      To update with Brew, run:
        brew update
        brew uninstall --ignore-dependencies libimobiledevice
        brew uninstall --ignore-dependencies usbmuxd
        brew install --HEAD usbmuxd
        brew unlink usbmuxd
        brew link usbmuxd
        brew install --HEAD libimobiledevice
        brew install ideviceinstaller

MacにiPhoneを接続してから、flutter doctorを実行すると消えました
