SOLID principle with Swift | STUPID

SOLID principle is an acronym created by Robert C Martin also unknown as Uncle Bob. It represents five principles for OOPS.

Single responsibility
Liskov Substitution
Interface Segregation
Dependency Inversion

Now the first thought that came to my mind is Why do we need this? Here is the answer, using these principles we can solve the problems of a bad architecture.

Fragility where A small change may break complete module it’s really very difficult to find this if you don’t have good test cases.

Immobility where A component is very hard to reuse in another project or we can say multiple places in the same project because of too many dependencies.

Rigidity where Single change requires lots of developer efforts because it affects several parts of the project.

Here I want to add principles will not turn a bad programmer into a good programmer you need a better judgment there. Principles have to apply with judgment and you must be smart enough to understand when to apply what.

I have also written one blog where they have mentioned one more acronym like SOLID and it’s STUPID. This may hurt your feeling but yes if you are following this you are writing stupid code.

Tight Coupling
Premature Optimization
Indescriptive Naming

Thank you for reading the quick introduction, In next blogs, I will try to define all principles with Swift Code.
