This should work
class PersistantStorage<T: Codable & Identifiable> {
func store(_ object: T) throws { }
func objectFor(_ key: T.ID) -> T? {
return nil
}
}
You could also write it like this:
class PersistantStorage<T> where T: Codable & Identifiable{
func store(_ object: T) throws { }
func objectFor(_ key: T.ID) -> T? {
return nil
}
}

Represents all your cards, in this case 8 cards in the array

I found a solution.
@FetchRequest(
entity: LifetimeInputs.entity(),
sortDescriptors: [NSSortDescriptor(keyPath: \LifetimeInputs.date, ascending: true)], predicate: nil
) var lifetimeInputsModel: FetchedResults<LifetimeInputs>
Becomes this (in my case)
@FetchRequest var lifetimeInputs: FetchedResults<LifetimeInputs>
init(nsPredicate: NSPredicate, sortDescriptors: [NSSortDescriptor]) {
let entity = LifetimeInputs.entity()
let fetchRequest = FetchRequest<LifetimeInputs>(entity: entity, sortDescriptors: sortDescriptors, predicate: nsPredicate, animation: .default)
self._lifetimeInputs = fetchRequest
}
The nsPredicate and the sortDescriptors must be passed to a parent view and you have to change/update (if you need to) them in that parent view.
Hope it works also for you

I think that the solution is in your previous thread, anyway here is the solution:
struct ContentView: View {
@State private var flip: Bool = false
var body: some View {
Group {
Button {
withAnimation {
flip.toggle()
}
} label: {
Rectangle()
.frame(width: 140, height: 170)
.foregroundColor(Color(.systemTeal))
.cornerRadius(20)
.rotation3DEffect(.degrees(flip ? 180 : 0), axis: (x: 0, y: 1, z: 0))
}
}
}
}
Post not yet marked as solved
struct ContentView: View {
@State private var flipped = false
var body: some View {
Group {
RoundedRectangle(cornerRadius: 20)
.frame(width: 140, height: 170)
.foregroundColor(flipped ? .red : .orange)
.padding()
.overlay(Text("Hello, world!").rotation3DEffect(Angle(degrees: flipped ? 180 : 0), axis: (x: CGFloat(0), y: CGFloat(10), z: CGFloat(0))).opacity(flipped ? 1 : 0))
.rotation3DEffect(flipped ? Angle(degrees: 180): Angle(degrees: 0), axis: (x: CGFloat(0), y: CGFloat(10), z: CGFloat(0)))
.animation(.default, value: flipped)
.onTapGesture {
flipped.toggle()
}
}
}
}
struct ContentView: View {
@State private var flipped = false
var body: some View {
Group {
RoundedRectangle(cornerRadius: 20)
.frame(width: 140, height: 170)
.foregroundColor(flipped ? .yellow : .purple)
.padding()
.overlay(Text("Hello, world!").rotation3DEffect(Angle(degrees: flipped ? 180 : 0), axis: (x: CGFloat(0), y: CGFloat(10), z: CGFloat(0))).opacity(flipped ? 1 : 0))
.rotation3DEffect(flipped ? Angle(degrees: 180): Angle(degrees: 0), axis: (x: CGFloat(0), y: CGFloat(10), z: CGFloat(0)))
.animation(.default, value: flipped)
.onTapGesture {
flipped.toggle()
}
}
}
}
Is this ok?
Or maybe this:
struct ContentView: View {
@State private var flipped = false
var body: some View {
Group {
ZStack{
RoundedRectangle(cornerRadius: 20)
.frame(width: 140, height: 170)
.foregroundColor(flipped ? .red : .orange)
.padding()
Text("Hello, world!")
.rotation3DEffect(.degrees(flipped ? 180 : 0), axis: (x: CGFloat(0), y: CGFloat(10), z: CGFloat(0)))
}
.rotation3DEffect(Angle(degrees: flipped ? 180 : 0), axis: (x: CGFloat(0), y: CGFloat(10), z: CGFloat(0)))
.onTapGesture {
withAnimation(.linear(duration: 1)) {
flipped.toggle()
}
}
}
}
}
I don't know if I understand what you mean but you can try user .overlay( Text("Hello, World!") ) as a modifier to the RoundedRectangle

Why do you absolutely want to use predicate ?
Because I Want to use it in @FetchRequest
