This is a very simple code in which there is only one button to start with. After you click the button, a list of images appear. The issue I have is that when I click on the new button to hide the images, the memory stays the same as when all the images appeared for the first time. As you can see from the images below, when I start the app, it starts with 18.5 mb, when I show the images it jumps to 38.5 mb and remains like that forever. I have tried various way to try and reduce the memory usage but I just can't find a solution that works. Does anyone know how to solve this? Thank you!
import SwiftUI
struct ContentView: View {
@State private var imagesBeingShown = false
@State var listOfImages = ["ImageOne", "ImageTwo", "ImageThree", "ImageFour", "ImageFive", "ImageSix", "ImageSeven", "ImageEight", "ImageNine", "ImageTen", "ImageEleven", "ImageTwelve", "ImageThirteen", "ImageFourteen", "ImageFifteen", "ImageSixteen", "ImageSeventeen", "ImageEighteen"]
var body: some View {
if !imagesBeingShown {
VStack{
Button(action: {
imagesBeingShown = true
}, label: {
Text("Turn True")
})
}
.padding()
} else {
VStack {
Button(action: {
imagesBeingShown = false
}, label: {
Text("Turn false")
})
ScrollView {
LazyVStack {
ForEach(0..<listOfImages.count, id: \.self) { many in
Image(listOfImages[many])
}
}
}
}
}
}
}

struct ContentView: View {
@State var listOfImages: [String] = ["One", "Two", "Three", "Four"]
@State var counter = 0
var body: some View {
VStack {
Button(action: {
counter += 1
}, label: {
Text("Next Image")
})
}
.background(Image(listOfImages[counter]))
.padding()
}
}
When I click on the button, counter increases and the next image is displayed as the background. The memory usage of the app increases as each image changes. Is there anyway to maintain a steady memory use?
