Hello, I have been working on SwiftData since a month now and i found very weird that every time i update a data inside a SwiftData model my app became very slow. I used the instrument if something was wrong, and i see memory increasing without releasing. My app have a list with check and unchecked elements (screeshot below). I just press check and unchecked 15 times and my memory start from 149mb to 361mb (screenshots below). For the code i have this model. final class Milestone: Identifiable { // ********************************************************************* // MARK: - Properties @Transient var id = UUID() @Attribute(.unique) var uuid: UUID var text: String var goalId: UUID var isFinish: Bool var createdAt: Date var updatedAt: Date var goal: Goal? init(from todoTaskResponse: TodoTaskResponse) { self.uuid = todoTaskResponse.id self.text = todoTaskResponse.text self.goalId = todoTaskResponse.goalId self.isFinish = todoTaskResponse.isFinish self.createdAt = todoTaskResponse.createdAt self.updatedAt = todoTaskResponse.updatedAt } init(uuid: UUID, text: String, goalId: UUID, isFinish: Bool, createdAt: Date, updatedAt: Date, goal: Goal? = nil) { self.uuid = uuid self.text = text self.goalId = goalId self.isFinish = isFinish self.createdAt = createdAt self.updatedAt = updatedAt self.goal = goal } } For the list i have var milestonesView: some View { ForEach(milestones) { milestone in MilestoneRowView(task: milestone) { milestone.isFinish.toggle() } .listRowBackground(Color.backgroundComponent) } .onDelete(perform: deleteMilestone) } And this is the cell struct MilestoneRowView: View { // ********************************************************************* // MARK: - Properties var task: Milestone var action: () -> Void init(task: Milestone, action: @escaping () -> Void) { self.task = task self.action = action } var body: some View { Button { action() } label: { HStack(alignment: .center, spacing: 8) { Image(systemName: task.isFinish ? "checkmark.circle.fill" : "circle") .font(.title2) .padding(3) .contentShape(.rect) .foregroundStyle(task.isFinish ? .gray : .primary) .contentTransition(.symbolEffect(.replace)) Text(task.text) .strikethrough(task.isFinish) .foregroundStyle(task.isFinish ? .gray : .primary) } .foregroundStyle(Color.backgroundComponent) } .animation(.snappy, value: task.isFinish) } } Does someone have a idea? Thanks
