I created two realm Object classes called : Master and Courses

class Master : Object , Identifiable {
    
    @objc dynamic var id = UUID()
    @objc dynamic var name : String = ""
    var courses = List<Course>()
    
}

class Course : Object , Identifiable {
    
    @objc dynamic var id = UUID()
    @objc dynamic var name : String = ""
    var parentMaster = LinkingObjects(fromType:Master.self , property: "courses")
    
}

ViewModel :

class AppState : ObservableObject {
    
    @Published var allmasters : [Master] = []

}

I have a simple function to return courses for each master here :

   func input(index: Int) -> List<Course> {
       
        return appState.allmasters[index].courses

    }

My problem is : what is the datatype of return for function?? I put List<Course> as a return type but the compiler give me this error :

Generic type 'List' specialized with too few type parameters (got 1, but expected 2)

It seems you are importing both SwiftUI and RealmSwift in the same file, both of which declare a List type.

If you want to return a RealmSwift.List, you need to declare the return type as such.

func input(index: Int) -> RealmSwift.List<Course> {   
    return appState.allmasters[index].courses
}
