hello! I'd like to ask you a SwiftUI question.
Based on the ReserveService file, I am implementing the part that lists and displays the desired data in ReserveView.
I want to complete the url in the 'fetchReserves' function by receiving the variable 'roomnum' from the ReserveView model to the ReserveService. However, Binding does not seem to work because ReserveService is not a view model. Is there any way I can get this variable from the viewmodel? If you don't understand my explanation, please ask the question again.
This is my first time asking a question. Please forgive me if there is something missing in my question
