Why am I getting this error? There's another post similar to this, but it doesn't have any answers.
import SwiftUI
struct ContentView: View {
@State var clicked = 0
var numberValue = [1: "won", 9: "Nein!", 69: "nice.", 123: "321", 666: "ILLUMINATI", 6969: "very nice."]
func addOne() {
clicked += 1
print(clicked)
}
var body: some View {
VStack{
Text("Clicker: The Game")
.font(.largeTitle)
.fontWeight(.bold)
.multilineTextAlignment(.center)
.offset(y: -225)
Text(numberValue[self.clicked] ?? String(self.clicked))
.font(.system(size: 69))
.offset(y: -125)
Button(action: addOne) {
Text("Tap me!")
.offset(y: -10)
.font(.system(size: 30))
.background(RoundedRectangle(cornerRadius: CGFloat, style: RoundedCornerStyle = .circular))
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}

This is just for clarification because I don't think it does. Every time I create a project using a game template thing, there's no option to use SwiftUI. When you create the project, it uses Storyboards and UIKit.
Hi! I've been messing around with Swift and SwiftUI for 2-4 weeks now. I decided to make a guide app or something that's a bit customizable. So, I searched for tutorials on how to save data locally. I found out Core Data is the framework for that job, and luckily, I found out it's in Apple's developer documentation website. The thing is, though, it isn't for SwiftUI. I think it's for Storyboards or UIKit.
Can I use CoreData with SwiftUI?
I just want users to be able to save their settings/preferences. My problem is that using Core Data with SwiftUI (not Storyboards) seems a bit too complicated.
Does it use custom views?
Is GM seed the final beta or something?
Is it stuck on portrait mode? There's no option that lets me change the orientation.
@State private var menuItems = ["Heroes", "Items", "Tips"]
var body: some View {
ZStack {
VStack {
ForEach(0 ..< menuItems.count) {_ in
Button(action: {}) {
Text("\(menuItems[$index])")
.foregroundColor(Color.white)
}
.padding(.horizontal, 75.0)
.padding(.vertical, 25.0)
.background(Color.gray)
}
}
}
I get an "Cannot find '$index' in scope"
var sum: Double {
let peopleCount = Double(numberOfPeople + 2)
let tipSelection = Double(tipPercentages[tipPercentage])
let orderAmount = Double(checkAmount) ?? 0
return orderAmount / peopleCount * tipSelection
}
Is this a function, a variable, or both?
I have a late 2012 iMac running Catalina. I find it really weird that Xcode 12 runs slowly because I can run Xcode 11 fine. It takes forever to build (around 2 minutes), simulate (around 5 minutes), and preview (around 3 minutes) on Xcode 12. Heck, I don’t even bother to toggle the live preview option. But, this wasn’t the case when I still used Xcode 11.
Will Apple be dropping support for older iMacs? How can I make it run faster?

I have 2 files that I want to work together or something.
The first is the main file: ContentView.swift. The second is the file where my other view is: KeysView.swift.
This is what KeysView contains:
struct KeysView: View {
var body: some View {
HStack {
Button(action: {
}) {
Text("1")
.padding()
.background(Color.black)
.clipShape(/*@START_MENU_TOKEN@*/Circle()/*@END_MENU_TOKEN@*/)
}
Button(action: {
}) {
Text("2")
.padding()
.background(Color.black)
.clipShape(/*@START_MENU_TOKEN@*/Circle()/*@END_MENU_TOKEN@*/)
}
Button(action: {
}) {
Text("3")
.padding()
.background(Color.black)
.clipShape(/*@START_MENU_TOKEN@*/Circle()/*@END_MENU_TOKEN@*/)
}
}
HStack {
Button(action: {
}) {
Text("4")
.padding()
.background(Color.black)
.clipShape(/*@START_MENU_TOKEN@*/Circle()/*@END_MENU_TOKEN@*/)
}
Button(action: {
}) {
Text("5")
.padding()
.background(Color.black)
.clipShape(/*@START_MENU_TOKEN@*/Circle()/*@END_MENU_TOKEN@*/)
}
Button(action: {
}) {
Text("6")
.padding()
.background(Color.black)
.clipShape(/*@START_MENU_TOKEN@*/Circle()/*@END_MENU_TOKEN@*/)
}
}
HStack {
Button(action: {
}) {
Text("7")
.padding()
.background(Color.black)
.clipShape(/*@START_MENU_TOKEN@*/Circle()/*@END_MENU_TOKEN@*/)
}
Button(action: {
}) {
Text("8")
.padding()
.background(Color.black)
.clipShape(/*@START_MENU_TOKEN@*/Circle()/*@END_MENU_TOKEN@*/)
}
Button(action: {
}) {
Text("9")
.padding()
.background(Color.black)
.clipShape(/*@START_MENU_TOKEN@*/Circle()/*@END_MENU_TOKEN@*/)
}
}
}
}
In ContentView, I'm trying to call the view using KeysView(), but I keep getting a Cannot find 'KeysView' in scope error.
I'm confused. If I get an error, I just replace it with the other and it just works, but what I don't know is why it works. Both share the same value with the variable they're bonded to, so what's the difference?
I always get errors whenever I use the normal for loop and the repeat loop.
ScrollView(.horizontal, showsIndicators: false) {
Image("sandwich0")
.resizable()
.frame(width: 100.0, height: 100.0)
Image("sandwich1")
.resizable()
.frame(width: 100.0, height: 100.0)
Image("sandwich2")
.resizable()
.frame(width: 100.0, height: 100.0)
}
Relevant code ^
My ScrollView isn't horizontal. It's vertical, but you can swipe horizontally. I can't upload an image here because I can't link to Imgur for some reason.
My code:
Text("alpha")
.font(.subheadline)
.background(RoundedRectangle(cornerRadius:
.strokeBorder(lineWidth: 1))
It works as expected, but there's no space between the border and the text.
