I think are you Forget to adding splash screen Default-568h@2x.png in to you Project please check Property and set required splash-screen Default-568h@2x.png (640 × 1136 pixels)
Ones you add this image in to you working Project, Remove old Build from device or Simulatore, clear Project and re build and check Hope you issue will solve.

Remember to set this set as default in your project info.
