Closed r0otx closed 1 month ago

r0otx commented 1 month ago

Thank you for library. I have problem. My app have repository, and mvvm architecture. All business logic make in view model, but if I add in vm InjectedObject(.profileRepository) var profileRepository show purple error: Accessing StateObject's object without being installed on a View. This will create a new instance each time. Why? How can fix it?

InjectedObject is meant for use injecting ObservableObjects into SwiftUI views. Use Injected in the VM.

If I use Injected in VM, UI can't reload after make changes. But if I use InjectedObject in view all right work :(

You can't use InjectedObject inside a view model and have it trigger updates any more that you can use another ObservableObject inside a view model and have it automatically trigger updates.

Use Injected to access the services your VM requires (e.g. APIs) and then assign the results to Published values in the VM.
