Swiftui development experience: the five most powerful principles that a programmer needs to master

In the programming world , We follow the principles of some people . Some are widely spread knowledge , But some don't usually say , Because it comes from personal experience , for example ：

• Never start programming without a solid idea of what you are going to do . This applies to the most diverse projects , Even the simplest program . Coding without a specific direction usually leads to rework .
• Simplicity is better than complexity . It's not just you , Everyone else must know what they are doing . Never despise comments .
• If you are working on a medium-sized project and have the necessary resources , Please consider using MVC framework . Correctly separating various files in the project makes development easier .
• Although it is tempting to create functions for complex things such as computation , But it's worth using your library for this . please remember , You usually don't have time to write code from scratch , And many libraries are created by individuals and organizations of subject matter experts .
• Divide and rule . If you have a big problem , Break it down into smaller parts and solve them . This helps / Improve your understanding of the problem , And make it easier to solve . This is also a basic algorithm construction technology .
• Reuse and decouple as much as possible . Write reusable and general-purpose functions / class / Code （ Within the scope of common sense and problem requirements ）. Do the same thing , Reuse others' code / Solution . It can save you time now or in the future .
  Write code for people, not machines . Don't write code that you won't understand tomorrow or that others won't understand . For writing code that only you know , You are not a better programmer （ in my opinion , On the contrary ）. Write code for people to understand .

Programming is a difficult task , Like many fields of knowledge , Only through a lot of practice and principles to learn .
