Generar un UUID en iOS desde Swift
En mi aplicación Swift de iOS quiero generar cadenas UUID (GUID) aleatorias para usar como clave de tabla, y este fragmento aparece para funcionar:
let uuid = CFUUIDCreateString(nil, CFUUIDCreate(nil))
Es esto seguro?
¿O hay quizás un mejor enfoque (recomendado)?

Prueba este:
let uuid = NSUUID().uuidString
print(uuid)
Swift 3
let uuid = UUID().uuidString
print(uuid)

También puedes usar la API NSUUID:
let uuid = NSUUID()
Si desea recuperar el valor de la cadena, puede usar uuid.UUIDString
.
Tenga en cuenta que NSUUID
está disponible desde iOS 6 en adelante.

let uuid = NSUUID().uuidString.lowercased()

Para Swift 3, muchos tipos Foundation
han eliminado el prefijo 'NS', por lo que accederías a él por UUID().uuidString
.
