Hi to everyone
I am developing a photo utility app in SwiftUI.
But there is something I don't understand about Image View's memory management. In my attempts it seems that when an image is created in SwiftUI it will never be destroyed (never deallocated in memory)
I tried this simple test view which shows one image at a time taken from a set of images loaded from the main bundle (Assets.xcassets).
This is the code:
struct ImageTest: View {
@State var index = 1
var imageName : String { "Image\(index)"}
var body: some View {
VStack {
Image(imageName)
.resizable()
.aspectRatio(contentMode: .fit)
Spacer()
Button(action:{ index += 1 }) { Text("Next") }
}
}
}
I thought that every time the "Next" button was clicked, a new image was created. Then the old one was destroyed. But it seems that this is not the case.
When I run the app I see the memory grow every time I press the button and the new image appears. Memory is never released.
I do not understand.
I hope someone can help me
Thank you
