@Injected vars not working after calling Resolver.reset()

[yosi199]

Hi, first let me say I really enjoy this library. Was thinking of writing my own but once I found out about Resolver I'm now using it.

One thing I'm trying to achieve in my SwiftUI app is clearing out all data after a user logs out. I'm using Resolver.reset() in order to clean all the dependency graph.

Right after I reset the graph, I navigate back to previous screen (login) and resolve all the dependencies I need, inline so that the user can login again. Something like this:

func onLogin() {
let authRepo: AuthRepository = Resolver.resolve
authRepo.login()
}

This works great and I'm able to relogin into the next screen. Here is where the problem - this next screen has a @StateObject viewmodel that get's all it's dependencies using the @Injected property wrappers and once the user performs an action that uses one of these dependencies - nothing happens. It won't crash, but also won't do the things I expect. Weird behaviour.

I'm sure I'm doing something wrong or don't understand the concept of resetting the graph. All depdendencies are .cached

Any idea what i'm doing wrong?

The 'graph' happens on a resolution where A depends on B which depends on C which depends on D.

Calling Resolver.reset should not be done. You basically lose all your registrations and they need to be recreated.

If you navigate to a new screen and not seeing inject happen correctly you might be seeing: https://stackoverflow.com/questions/60129552/swiftui-navigationlink-memory-leak/71829180#71829180

Finally, you might consider using my newer DI framework, https://github.com/hmlongco/Factory

Note there's a couple of examples in the Factory readme on session state.
