Generic Error Handling in SwiftUI

Error handling is something that I usually put out to fix at last and print the error in the catch statement. As I grow as a developer, I cannot do this anymore in my apps, and I try to incorporate the process of error handling while writing the methods and writing tests for them.

One requirement I recently faced was generalizing error handling so that I can handle the error-related code in one place and directly use it everywhere else.

I started with three ideas in mind:

• A error protocol out of which I can create different error structures
• A base view model that takes care of handling the error.
• A view modifier responsible for the error alert shown to the user.

So let’s explore some error handling!

Conclusion

These views are more of me being lazy, but I like them when working on a project with hundreds of them.
