Estoy trabajando en un proyecto escolar y estoy tratando de registrar datos almacenados de un juego que hice en unidad.

Mi problema es que quiero enviar por correo electrónico los datos verdaderos de la aplicación. Todo funciona bien, el correo electrónico se envía con los datos, etc. Pero cuando construyo la aplicación en un dispositivo iOS no está enviando el correo electrónico.

No tengo ningún error en la unidad, pero aparece este error en Xcode cuando construyo la aplicación. Vea el error a continuación. Espero que alguien pueda ayudarme.

Saludos,

Georgi Iliev
