    Is this reported by the submission of the App Store?
    It seems the device can't run your application. Have you added the device's UDID?

    App crashed only first time launch at release mode. Even it crashed at beta testing also. Second time it open as normal. I didn't recognized the issues. Please help!

    If you test this with TestFlight, could you please provide more specific logs?
    Or try to integrate some analytics such as App Center to help us collect the crash logs.
