I agree the best bet is to teach yourself and puts some apps in the store.
I having been studying for a couple of years, I have 6 apps in the store and am just starting to look for a job in this industry. There are a lot of iOS jobs but not that many junior positions. Most job descriptions ask for 1 - 2 years professional experience.
But there are junior positions and if you are really committed then I am sure you can make it.
I had one job interview so far, actually it was for a slightly more senior role than I am expecting I could be able to get and I just missed out apparently due to someone else having more experience.
But it was good to get experience of an interview and what sort of questions they ask.
Thanks for the info.
It would be good to get some more advice from you seeing as you are a fellow UK member.
