What do you need to learn to start freelancing on iOS?

Question

iOS

Hello. Question on a subject.
For fifteen years I have been writing under Windows, mostly databases, and a little PHP + Javascript.
I have never held a macbook in my hands, I always preferred Nokia, HTC to an iPhone (that is, I am also unfamiliar with an iPhone).
The question arose - What do you need to learn to start freelancing under iOS?
The only thing I know so far is the Objective-C language, ide - Xcode.
It is enough to understand Objective-C or you need to know some libraries / frameworks, etc.
In general, what do I need to know in order to boldly go to odesc / elance and take on tasks under iOS?

Answer 1

Everything is much easier than it seems.
To get started, you MUST have OS X (google install on a virtual machine, hackintosh, or buy a Mac).
After you get comfortable with the operating system, install Xcode (as an option, you can take the IDE from JetBrains, but I recommend Xcode to start with).
At this stage, you don’t need to pay for any developer programs - Xcode is free, you can test it on the simulator.
Then we choose a series of tutorials (for example www.appcoda.com ) to make a couple of HelloWorld level projects.
After that, it is worth deciding whether to buy the $100 iOS developer program (+ real iOS device) for $100.

Answer 2

If they had been writing under Windows for 15 years, such questions would not have arisen.
You need the iOS SDK, and not just knowledge of PL.

Answer 3

Buy a Mac, pay $100 a year to Apple. And so - Apple puts out a lot of videos, how to do what, I think you know how to google

Answer 4

"What do you need to learn?" - you don’t need to learn anything, anyway, you won’t learn all the documentation for all frameworks.
You just need to be able to use the documentation and have experience in REAL iOS programming.
At a minimum, you need to buy a Mac and some real iOS device. After that, make a few READY applications for testing. Quality assurance is if your application is taken to the App Store. But you have to pay $100 for it.
So, if you recoup at least your spent $100 from the App Store (I'm not talking about money for a Mac and iOS gadget), then you can BOLDLY take on tasks. I think it will take about a year (if you're a really cool programmer) between the first spending of money and the first manifestation of your courage in iOS programming.
