Although I have many skills outlined on my resume, I want to add another practical skill, in case my current skills become obsolete.
So, I have been toying with the idea of teaching myself Swift or some other iOS programming language in order to be able to create apps for the iPhone.
Out of the many new business skills a professional could learn, would this be the best?
If so, how long does it take to learn and is it extraordinarily difficult? Are there are good and free tutorials online that will successfully teach the lay person such a programming language?
