Xcode se bloquea cuando bash crear una salida desde un file UIWebview to Header

Actualmente estoy usando Xcode 5 en mi Macbook Pro que está ejecutando OSX Yosemite. Estoy intentando crear una salida desde una UIWebview a un file de encabezado. Cuando suelto el mouse para crear la connection, Xcode se bloquea y se bloquea. Esto sucede repetidamente sin importar lo que haya hecho. He intentado reiniciar Xcode y mi Macbook. ¿Alguien más tiene este problema o sabe cómo solucionarlo? ¡Gracias!

Agregué los loggings del crash (no pude include la traza inversa porque superó los caracteres máximos en el cuerpo)

Creo que debería declarar un IBOutlet en su file de encabezado. Y luego, en Storyboard, intenta conectar el file de encabezado.

¿Alguna vez trató de limpiar su producto (Producto-> Limpio)? Luego, abra el file xib como código fuente y elimine su información de IBOutlet. Tal vez XCode se confunda acerca de su IBOutlet.
