Circular Dependency

📚 Official Books Server Side Swift with Vapor

Can anyone give me some clue on how can I resolve circular dependency?

What is the circular dependency you’re getting? If you could show your Package.swift and error message that would be great!

// swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.

Here is my Package.swift file

4

when I initialize UserController in config.swift file. Compiler gives this error

5

What’s the error? I can’t see anything attached

6

Error: Cannot find ‘UserController’ in scope

UserController is defined in API directory, while config is inside MeadowsViewWeb directory.

Both API and MeadowsViewWeb directory are the same level of hierarchy wrt directory structure

7

So assuming you’re getting the error in MeadowsViewWeb you need to import API and also make sure the UserController is public

Do you get the same error from the command line? And does anything in your API do import MeadowsViewWeb?
