Using `@ObservedObject` in a function

No real intruduction for this, so I'll get to the point: All this code is on GitHub: https://github.com/the-trumpeter/Timetaber-for-iWatch But first, sorry;

/*
I got roasted,
last time I posted;
for not defining my stuff.
This'll be different,
but's gonna be rough;
'cuz there's lots and lots
to get through:
*/

//this is 'Timetaber Watch App/Define (No expressions)/Courses_vDef.swift' on the GitHub:

struct Course {
    let name: String
    let icon: String
    let room: String
    let colour: String

    let listName: String
    let listIcon: String
    let joke: String

    init(name: String, icon: String, room: String? = nil, colour: String,
         listName: String? = nil, listIcon: String? = nil, joke: String? = nil)
    {

        self.name = name
        self.icon = icon
        self.room = room ?? "None"
        self.colour = colour

        self.listName = listName ?? name
        self.listIcon = listIcon ?? (icon+".circle.fill")

        self.joke = joke ?? ""
    }
}

//this is 'Timetaber Watch App/TimeManager_fDef.swift' on the GitHub:

func getCurrentClass(date: Date) -> Array<Course> {
//returns the course in session depending on the input date
//it is VERY long but
//all you really need to know is what it returns:
//basically: return [rightNow, nextUp]
}

/*
I thought that poetry
would be okay,
But poorly thought things through:
For I'll probably find
that people online
will treat my rhymes like spew.
*/

So into the question:

I have a bunch of views, all (intendedly) watching two variables inside of a class:

//Github: 'Timetaber Watch App/TimetaberApp.swift'
class GlobalData: ObservableObject {

    @Published var currentCourse: Course = getCurrentClass(date: .now)[0] // the current timetabled class in session.

    @Published var nextCourse: Course = getCurrentClass(date: .now)[1] // the next timetabled class in session
}

...and a bunch of views using them in different ways as follows: (Sorry, don't have the characters to define functions called in these)

import SwiftUI

//Github: 'Timetaber Watch App/Views/HomeView.swift'
struct HomeView: View {

    @StateObject var data = GlobalData()

    var body: some View {
        //HERE:
        let icon = data.currentCourse.icon
        let name = data.currentCourse.name
        let colour = data.currentCourse.colour
        let room = roomOrBlank(course: data.currentCourse)
        let next = data.nextCourse

        VStack {

            //CURRENT CLASS
            Image(systemName: icon)
                .foregroundColor(Color(colour))//add an SF symbol element
                .imageScale(.large)
                .font(.system(size: 25).weight(.semibold))

            Text(name)
                .font(.system(size:23).weight(.bold))
                .foregroundColor(Color(colour))
                .padding(.bottom, 0.1)

            //ROOM
            Text(room+"\n")
                .multilineTextAlignment(.center)
                .foregroundStyle(.gray)
                .font(.system(size: 15))

            if next.name != noSchool.name {
                Spacer()

                //NEXT CLASS
                Text(nextPrefix(course: next))
                    .font(.system(size: 15))

                Text(getNextString(course: next))
                    .font(.system(size: 15))
                    .multilineTextAlignment(.center)
            }
        }.padding()
    }
}

// Github: 'Timetaber Watch App/Views/ListView.swift'
struct listTemplate: View {

    @StateObject var data = GlobalData()

    var listedCourse: Course = failCourse(feedback: "lT.12")
    var courseTime: String = ""

    init(course: Course, courseTime: String) {
        self.courseTime = courseTime
        self.listedCourse = course
    }

    var body: some View {
        let localroom = if listedCourse.room == "None" {
            "" } else { listedCourse.room }
        let image = if listedCourse.listIcon == "custom1" {
            Image(.paintbrushPointedCircleFill)
        } else { Image(systemName: listedCourse.listIcon) }
        HStack{

            image
                .foregroundColor(Color(listedCourse.colour))
                .padding(.leading, 5)

            Text(listedCourse.name)
                .bold()

            Spacer()

            Text(courseTime)
            Text(localroom).bold().padding(.trailing, 5)

        }
        .padding(.bottom, 1)
        .background(data.currentCourse.name==listedCourse.name ? Color(listedCourse.colour).colorInvert(): nil) //HERE

    }
}

struct listedDay: View {
    let day: Dictionary<Int, Course>
    var body: some View {
        let dayKeys = Array(day.keys).sorted(by: <)
        List {
            ForEach((0...dayKeys.count-2), id: \.self) {
                let num = $0
                listTemplate(course: day[dayKeys[num]] ?? failCourse(feedback: "lD.53"), courseTime: time24toNormal(time24: dayKeys[num]))
            }
        }

    }
}

struct ListView: View {
    var body: some View {

        if storage.shared.termRunningGB && weekdayFunc(inDate: .now) != 1
            && weekdayFunc(inDate: .now) != 7 {
            ScrollView {
                listedDay(
                    day: getTimetableDay(
                        isWeekA:
                            getIfWeekIsA_FromDateAndGhost(
                                originDate: .now,
                                ghostWeek: storage.shared.ghostWeekGB
                            ),
                        weekDay: weekdayFunc(inDate: .now)
                    )
                )
            }

        } else if !storage.shared.termRunningGB {
            Text("There's no term running.\nThe day's classes will be displayed here.")
                .multilineTextAlignment(.center)
                .foregroundStyle(.gray)
                .font(.system(size: 13))

        } else {
            Text("No school today.\nThe day's classes will be displayed here.")
                .multilineTextAlignment(.center)
                .foregroundStyle(.gray)
                .font(.system(size: 13))
        }

    }
}

//There's one more view but I can't fit it for characters.
//On GitHub: 'Timetaber Watch App/Views/SettingsView.swift'

So... THE FUNCTION: This function is called when changes are made that will affect the correct output of getCurrentClass. It is intended to reload the views and the current/next variables to reflect those changes.\

//GHub: 'Timetaber Watch App/StorageManager.swift'
func reload() -> Void {

    @ObservedObject var globalData: GlobalData //this line is erroring, I don't know how to fix it. Is this even the best/proper way to do this?

    let courseData = getCurrentClass(date: .now)

    globalData.currentCourse = courseData[0]
    globalData.nextCourse = courseData[1]
//Variable '_globalData' used by function definition before being initialized
//that is the error appearing on those above two redefinitions.

    print("Setup done\n")
}

Thanks!
