My problem is that i have (in SwiftUI) a ScrollView with an foreach inside. Know when the foreach loads all of my entries i want that the last entry is focused.
I did so
ScrollViewReader
in iOS14 SwiftUI gains a new ability. To be able to scroll in a ScrollView up to a particular location. There is a new type called ScrollViewReader
which works just like Geometry Reader
.
The code below will scroll to the last item in your View. I reused your code adding some color for better visualisation. So this is your struct for 'Entry' I guess:
struct Entry {
static var index = 0
var name = "Entry number "
func getName() -> String {
Entry.index += 1
return self.name + "\(Entry.index)"
}
}
And the main ContentView:
struct ContentView: View {
let colors: [Color] = [.red, .blue, .green]
var entries: [Entry] = Array(repeating: Entry(), count: 10)
var body: some View {
ScrollView {
ScrollViewReader { value in
ForEach(0..
Try to run this in the new version of SwiftUI announced at WWDC20. I think it is a great enhancement.
