Honestly programming is mostly about understanding and learning code other People did and how to work together. If you think you can do the job with the time you programmed apply. List the years you did programming language x for x years as a free lancer.
I've noticed there's a job listing that requires at least 14 years of coding experience, including at least 6 years of iOS programming, and I'm assuming that's the norm for programming jobs.
No, that is definitly not the norm for programming. Alot of People get Jobs with requirements like that one with hardly half the experience
I'm assuming "experience" will include any relevant college courses taken, correct?
No, an college course is counted as education not experience. Especially if you get a certificate.
Most of experience requirements are just to weed People from applying, my opinion atleast.
Since I would have no former employing company - and therefore, no formal record of number of years of experience - what can I do now to ensure my ability to prove my eligibility for a job in the future?
But honestly find something lower down the line, because it feels atleast on paper, that you are overestimating your capabilities.
I am currently a freelance developer. However, I would like to be able to prove my eligibility for a job to any future employer.
Put up the Projects you did? Assuming you did work, this is not ment to be mean the market is tough everywhere, also you don't state how Long you have been freelancing or if you did annything at all.
Hope this helps, and don't hessitate to ask for clarification if something is unclear.
