Make the Most of Your 24 Hours

Bitter Experience

I started iOS as a 2-year-experience .NET developer. The salary range for a junior iOS dev is a little bit lower than the amount for a 2-year-experience develop get. I wanted to make myself stronger, earn more experience. I had a misconception of working and learning. I thought, freelance projects will help me strengthen my knowledge and experience. So I tried to get as more as possible freelance projects. And my nightmare started from here.

I had no time to spend with my family, no time to work on personal improvement, no time to go out with friends, no time at all. All of my time was used up on my freelance work from coding new features, fixing bugs and much more. I was killing myself working odd hours and missing out on quality time with my family and friends.

I made a mess, uncountable technical debts, bugs, with the project. I was angry with everyone and myself. And the company project was affected. I brought more bugs there, dozens of stupid bug

Should I implement UI with Storyboard or by Programmatically?
View Auto_Layout_Programmatically.md

Auto Layout with Storyboard and Programmatically

I started iOS development as a .NET developer. My first impression, Storyboard is really really interesting. 80% UI of my apps is built in Storyboard. I can't imagine how I can develop iOS without Storyboard.

There are many discussions about Auto Layout with Storyboard or Programmatically is better. But no one wins. Everyone has own reason and belief.

This post is my personal opinion. It's written by a developer can't live without Storyboard, and now he abandons it.

3 reasons why he changed to Auto Layout by programmatically.

Why do I abandon Storyboard?

You can’t perform that action at this time.
