Compilatore Apple LLVM 4.1 Errore

Question

Im molto nuovo per la programmazione iOS. Im letteralmente solo cercando di compilare un progetto vuoto, che per quanto ne so dovrebbe funzionare, ma sto correndo in un errore:

fatal error: error in backend: IO failure on output stream.

Chiedo solo qualcuno ha qualche soluzioni o idee a quello che sto facendo male?

Answer 1

Probabilmente lo spazio su disco è esaurito. Dove si trova la cartella di creazione? Potrebbe non essere consentito scrivere e causare quell'errore.

Answer 2

Aveva questo problema, ha provato la maggior parte delle cose, ma alla fine un riavvio di OSX ha risolto il problema per me.

Answer 3

Derek è corretto. Nel mio caso il disco RAM che utilizzo per i dati derivati ​​da XCode era pieno.
