Make sure your iOS developers now - the future of learning

This article, if you're an iOS developer also just promoted to bottleneck in the development of confusion, may wish to stop your footsteps, spend five minutes a look, maybe there is you need! End of the article there are eggs

Common singing group in sorrow

iOS now how in the end? Why die?
Many years of development experience in September and October can not get invited to several interviews, `offer` also difficult
Now not to change jobs, I feel now is the era of `` big front-end.
Now older, it is not very appropriate to continue to do a programmer!

Everywhere is full of anxiety for iOS Quotes

First, iOS market analysis

A mature IT developer must think to calm, learn - to meet the anxiety - turn pressure into motivation

①: Open BOSS straight employed (after all, most programmers quit looking for work is the use of this platform is typical) to Beijing -iOS search element! I analyzed the iOS market by following a table for everyone.

Because of the time to analyze the reasons just before five, because it is one a number of pages, there may be numbers are not very accurate

Salary	The number of jobs	Age requirements	Company Size
15K or so	40 parts	1--3 years	20-99
20K or so	63	3--5 years	100-499
About 30K	93 parts	3--5 years	100-499-1000 more
30K more	33 parts	3-5- above	499-1000 more

②: start analyzing 20-30K job recruitment requirements

③: Throughout the BOSS straight recruited analysis draw the following

A: Now iOS market recruitment needs to fall `20-30K`
B: `work experience in claim 3--5 years'
C: company size falls `100-499-1000`
D: capability condition selected from the brush
The underlying principle almost become an essential capability
Instead UI capabilities slowly in the recruitment requirements of the blackboard there is no direct
Architecture and performance optimization capabilities than previous requirements or relatively flat
The ability to share data algorithm structure is relatively large
Cross-platform capability also occupies a relatively high

Second, analysis of their current situation

Analysis of the basic information

This small non-Jike born partner, specialist qualifications.
Done a few years of business sales, behind the switch to start learning IT
After learning iOS development outsourcing company went to a three-year, quit another small company to develop two years, went out of business!
5 years of development experience, about 30, now fighting in Beijing!
After the company went bankrupt, September and October start looking for work, got 7 interview invitation, there is no suitable offer!

Analysis of professional skills

Here is a case of ordinary skill in the resume, you can also compare your resume

Summary : The professional resume writing skills is quite held in the 1950s in! But apparently it did not meet a requirement 20-30K - 5-year capacity development needs!

More involved too basic elements: simple interest, Agent, Block Communications, iOS automatic layout, OC and JS interactivity
Grasp something seemingly familiar with all know, and did not address the underlying principle
We do not have much expertise counterparts content analysis of the above: performance optimization, schema design, the underlying principle
No more prominent bonus items!

Analysis of project experience

I am here because taking into account the individual's privacy (although already authorized) there is no information about the company posted

This is just a brief introduction to the work, and are ground service layer , such as project experience is not enough, at least not see the shadow of a mature developer!

A senior iOS developer in the end what should have

Now in 2019, iOS developers do face a lot of problems:

There are a lot of beginning a career change (I'm not here to analyze the pros and cons of a career change, all of you to decide);
There is still a lot of confusion;
Of course there are a lot of frenzied media attention sunrise!

Here with those who left the industry would like to iOS hard work of a small partner, analyze a senior iOS developer in the end what should be mastered

1: the ability to explore the underlying

Many people will irony: the interview made aircraft carrier, tighten the screws to work! In actual fact, the high demands of the interview is a must for an outstanding demand units for iOS!

iOS开发实现的确有很多的方式，但是一个真正懂得原理的开发人员在日后的开发工作中是非常重要。我见过一些开发人员：遇到BUG都是直接面向百度，不知道为什么直接 `command + c`/`command + V` OK,解决了，打版走人，下次又遇到了还是要面向百度，其中浪费的时间和小伙伴之间的沟通成本可想而知！
底层原理只是你在工作开发中偷懒而逃避选择使用而已（或者全然不太了解）
技术不断更新，底层原理是永恒根基
底层原理是非常重要的，只有真正掌握原理才能迎接未来无限可能。

下面是我推荐大家学习的内容：

OC 底层探索篇也是大家熟悉而又陌生的地方，平时处处用，就是不知道为什么！

2：性能优化以及架构能力

只要你面试要求 20-30K 必然要求性能优化能力！

怎么优化启动速度，应用包的瘦身！
界面优化（卡顿检测以及分析解决）
内存管理方面也是面试以及平时开发的重灾区！
架构并不属于性能优化，但是我要求每一个 3年以上开发 都要有一定的架构思维！

3：数据结构算法

数据结构算法应该是每一个程序员必备的根据。

一个程序员需要两样东西：智商和勤奋

英文能力衬托你的勤奋度
数据结构算法反馈你的智商等级

数据结构与算法并不只是抽象的概念，掌握好的话可以写出更高效、运行得更快的代码，这对于如今盛行的网页和移动应用开发来说尤为重要。如果你最近一次使用算法是在大学课堂上或求职面试时，那你应该还没见识到它的真正威力！

这个主题的大多数资料都有一种通病——晦涩难懂。满纸的数学术语，我觉得一种有趣的学习方式也是非常重要的！

4：跨平台能力

跨平台的方案有很多：

如上表所示， RN 、 Weex 采用的技术方案大体相同，它们都使用 JavaScript 作为编程语言，然后通过中间层转换为原生的组件后再利用 Native 渲染引擎执行渲染操作。而 Flutter 直接使用 skia 来渲染视图，而 Flutter Widget 则使用现代响应式框架来构建，和平台没有直接的关系。

从性能方面来说， Flutter 的性能理论上是最好的， RN 和 Weex 次之，并且都好于传统的 WebView方案

而从社群和社区的活跃来看，RN和Flutter无疑是最活跃的

总结：针对现在的行情比较我个人推荐大家学习：Flutter

同时现在很多人也开始着手学习了
如何衬托你的优势，我个人还要推荐在平时入门到项目的过程，不妨花点时间探索了一下背后的原理：渲染的流程，`Flutter`和原生的共存通讯优化
下面这张思维导图大家可以参考学习

5：技术储备以及加分项

现在的iOS开发为什么会遇到瓶颈是因为 前面储备过少，坐吃山空！技术不断更新的时代，我希望你沉下心来与时俱进，不断储备技能为自己加分

这里我推荐学习：视觉方向！ 无论直播还是小视频，图形图像处理成为必然的技能，在即将到来的5G时代里，这一块技术必将成为你与其他开发人员差距的赛点！

同时也推荐大家学习：应用安全攻防方向 逆向安全这些年越来越被我们熟知并且需要！一个高质量安全的应用程序必将是你薪酬翻番的谈资！

综合总结

在现在这个群雄逐鹿的iOS市场，我希望你守住自己的浮躁，扛着压力向前冲！学习的路上必然艰难，但是请你记住下面这段话。

一个优秀的人从不拒绝知识，更何况是一个优秀开发者！！！

你要想站稳自己，未来岗位、薪酬待遇持续增长，我希望你保持学习，无论是：iOS底层、数据结构算法、Flutter、架构性能优化、视觉与逆向安全攻防 学就完事了！
