What should be in an iOS developer's portfolio? Is it the same for the web? How many jobs?

Question

iOS

Let me simplify: from what point can you try your luck in receiving orders? For example, a couple of months ago, I accidentally woke up as a front-end developer (before that, my background was limited to low-level programming under Linux in C for quite a long time). They slipped me a good part-time job without even asking if I knew JavaScript. I had to quickly master JavaScript, Backbone, Bootstrap in a week. On the other hand, I stopped being afraid of the web and even out of inertia began to write a simple toy with a Go backend. If it were not for the interest in the latter, it is unlikely that I would continue to do this at all. Mastering something just for the sake of perspective is boring to me to disgrace. Give us a project, we'll figure out the technologies there, something like this (approximately according to the same principle, I now turned out to be a GUI developer on Qt). Because there is a risk that for some reason I'm going to have to move to a place where I won't be eligible to be employed at all, I ask this question: can I convince someone with this toy that I'm capable of web development? Similarly, about iOS, which is of interest to me purely for financial reasons (it so happened that I don’t understand the hype around mobile applications at all). How many applications need to be riveted "on the table" so that they want to talk to me? All my life, changing my profile, I traveled only on the fact that I convinced the employer of my ability to learn, and demonstrated it. And with freelancing, it won’t work that way, which scares me a little. which I am interested in purely for monetary reasons (it so happened that I do not understand the hype around mobile applications at all).

Answer 1

No need to rivet "on the table" - better in the AppStore or Github.
