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!
