Human evaluations are difficult, because they are all opinions. Human evaluations are very difficult. Because they are all someone’s opinions. I found it. Human vertical and horizontal evaluations are all stood on someone’s opinions. So that there is no perfect evaluation. If some consultants bring to you perfect human resource evaluation, the consultants are liars.
2018/6/10. Java & Swift
I have learned Swift Programming Language. It’s suitable for beginners of programming, but return from Swift may lower than I expected... I was wrong about this issue, what language I should learn.
Android phones’ share may be over 70%, but it’s 40-50% in Japan. So I misunderstood that learning how to make iPhone app is useful skill in the world. But in the world, Java programming language is standard in smartphones, and it will be kept.
There is another problem about app making. Long & difficult review for iPhone app, this is heavy problem. If I want to release 3 or 4 apps, it takes time more than android apps. I know this review is necessary for brand name “Apple”.
Learning cost of Swift is very low, so Swift is good for initial programming language. And return from Java programming, is better than Swift.
And I want to add one thing, programming for smart phones is easy to understand what I am learning. Because device is my hands, and testing original app on my iPhone is very easy. So I can see the programming results soon. This is big impact on learning. PDCA cycle is shorter.
