Summary of iOS development

The most diligent to learn
There is a word called technical multi-body, programming is a very fast replacement of the work. Every year there are new technologies, and I think it would be impossible to be a good programmer with only one language.
So, how do you choose your second door, or even the third language?
I feel I have to try more on my own, from December through February 15, I've been experimenting with different languages and frameworks, from node. js to Golang to Python and learning a little bit of erlang in the middle.
I think the most suitable second language for iOS development is Python,python is really too good to use, and natural for UNIX systems, simple syntax, a variety of libraries, not exaggeration to say, everything. It is very useful to learn python well.
1 is a very good combination of Python and UNIX systems, you can write many scripts in Python to improve your productivity.
2 is a very quick introduction to Python, buy a headfirst Python tutorial and learn it quickly.
3 is Python's job prospects are also very good, even if you want to change careers, Python's treatment is not much worse than iOS.
I hope you can find an interesting language to study in your spare time.
