Hi, in this code it gives me the warning "Result of 'Text' initializer is unused" near Text("(Number)").
Does someone know what exactly mean this warning and how can I fix it?
Thanks in advance
struct NewView: View {
var body: some View {
Button {
tapped()
} label: {
Text("hello")
}
}
}
func tapped() {
Text("\(Number)")
}
struct NewView_Previews: PreviewProvider {
static var previews: some View {
NewView()
}
}

Hello everyone.
I would like to create a button in SwiftUI, which initially will display some text and with the click of the user will transform to a number (like initially the button displays "click me to add a number" and when I click on it'll immediately displays number "1" ). Can anyone help me with how to do this? Thanks
Hello there!
I would like to print the number 5 on the screen when I click the Button, but I don't know how I can do it... if I write print("5") it prints me the number 5 in the debug area of Xcode. Can someone help me to figure out this?
Here's may code
Thanks a lot
Button {
} label: {
ZStack {
Circle()
.frame(width: 90, height: 90)
.foregroundColor(Color(.systemBlue))
.opacity(0.5)
Text("5")
.font(.largeTitle)
.bold()
.foregroundColor(.black)
}
.frame(width: 90, height: 90)
}

.foregroundColor(self.flipped ? .red : .orange)
.padding()
.rotation3DEffect(self.flipped ? Angle(degrees: 180): Angle(degrees: 0), axis: (x: CGFloat(0), y: CGFloat(10), z: CGFloat(0)))
.animation(.default)
.onTapGesture {
self.flipped.toggle()
}
}

Hello! I was trying to create a cards game following the Stanford University CS193p tutorial and I had a problem, in the tutorial they didn't add any animation and I would like to add one but I can't understand where exactly I have to write the command. Can someone help me?
Thank you very much!
My code:
import SwiftUI
import PlaygroundSupport
struct ContentView: View {
var body: some View{
HStack {
CardView()
CardView()

}
struct CardView: View {
@State var isFaceUp = false
var body: some View {
ZStack {
let shape = RoundedRectangle(cornerRadius: 20)
if isFaceUp {
shape.fill().foregroundColor(.white)
shape.stroke(lineWidth: 3)
Text("😀").font(.system(size: 80))
} else {
shape.fill()

Hello there!
I want to create a cards game, and I'm creating it following the Stanford University's tutorial. I followed the video step by step but there is a warning that In the video doesn't appear. Can someone help me to fix it?
Here's the link of the video: [https://www.youtube.com/watch?v=oWZOFSYS5GE&t=671s)
This is my code:
import SwiftUI
struct ContentView: View {
let viewModel: EmojiMemoryGame
var body: some View {
VStack {
LazyVGrid(columns: [GridItem(), GridItem(), GridItem()]) {
ForEach(viewModel.cards) { card in
CardView(card: card)
.aspectRatio(aspectRatio, contentMode: .fit) // here's the first error which says "Cannot convert value of type '(CGFloat?, ContentMode) -> some View' to expected argument type 'CGSize'"
}
}
.padding()
.foregroundColor(Color(.systemTeal))
Spacer()
Button {
emojiCount += 1
if emojiCount == 10 {
aspectRatio = 9/3
}
ì
if emojiCount > 17 {
print("Card finished")
}
} label: {
Text("Add Card")
}
}
}
}
struct CardView: View {
let card: MemoryGame<String>.Card
var body: some View {
ZStack {
let shape = RoundedRectangle(cornerRadius: 20)
if card.isFaceUp {
shape.fill().foregroundColor(.white)
shape.stroke(lineWidth: 3)
Text(card.content).font(.system(size: 50))
} else {
shape.fill(.orange)
}
}
}
}
struct ContentView_Previews:
PreviewProvider {
static var previews: some View {
ContentView(viewModel: game) //here's the second error which says "Cannot find 'game' in scope"
}
}
Helle everyone!
I was preparing for this year's Swift Student Challenge, and I have some questions about it. I know that Apple every year changes something in the Challenge, but I want to be ready. As I know for participating to the challenge I have to build a playground in Swift Playgrounds. So for that in Swift Playgrounds I have to use SwiftUI kit or build it in another way?
PS: if someone knows some Swift Playgrounds tutorials please suggest me here.
Thank you very much!
Hi everyone, can anyone tell me how can I create images for Xcode assets. Because now I want to create my own image not using the readymade.
Thank you!
Hi everyone, can anyone explain me the difference between SwiftUI and UIKit?
Thank you.
Hi everyone,
I want to use SceneKit in Swift Playgrounds, or import the Xcode project with SceneKit into Swift Playgrounds. Is it possible?
Hello everyone,
I decide to send a feedback in the Feedback app about the software beta version. But I have a question about it, when I post my feedback only Apple team can see it or it's visible to anyone?
Thanks in advance.
Hello everyone,
Can someone tell me how to move the circle in the same position of the arrow (like to go up if I press up, down if I press down... and so right if I press right) but it doesn't go right, I can't know why. Please can someone help me to figure out this?
Here's the code:
import SwiftUI
import PlaygroundSupport
struct ContentView: View {
@State var offset: CGFloat = 0
var body: some View {
Circle()
.frame(width: 80, height: 80)
.position(x: 140, y: 140 + offset)
Spacer(minLength: 20)
Button(
action: {
offset += 20
}, label: {
Image(systemName: "arrowtriangle.down.circle.fill")
.resizable()
.foregroundColor(.blue)
.frame(width: 70, height: 70)
.padding()
}
)
Button(
action: {
offset += 20
}, label: {
Image(systemName: "arrowtriangle.right.circle.fill")
.resizable()
.foregroundColor(.blue)
.frame(width: 70, height: 70)
.padding()
}
)
}
}
PlaygroundPage.current.setLiveView(ContentView())
Thanks in advance.
