process launch failed hatası

Arkadaşlar xcode da uygulamayı derlerken "process launch failed: timed out waiting for app to launch"  hatasını veriyor. Çalışırken hiç bir hata yok sadece başlarken veriyor. Sebebini anlamadım ama bu şekilde bir kaç kere gönderdim App Store bu şekilde hatayla uygulamayı reddetti.
