Hi!
I've encountered strange bug in iOS 26. The MultiDatePicker component exhibits unreliable behavior when attempting to deselect previously chosen dates. Users often need to tap a selected date multiple times (e.g., tap to deselect, tap to re-select, then tap again to deselect) for the UI to correctly register the deselection and update the displayed state.
This issue does not occur on iOS 18 or Xcode 26 previews, where MultiDatePicker functions as expected, allowing single-tap deselection. The bug only occurs on physical device or simulator. I can't lie, I have multidatepicker as crucial component in my larger app and can't really find a solution to this. Has anyone encountered this problem before?
Here is the code to replicate the issue:
import SwiftUI
struct ContentView: View {
@ State private var selectedDates: Set = []
var body: some View {
NavigationStack {
Form {
Section {
MultiDatePicker("Select Dates", selection: $selectedDates)
} header: {
Text("MultiDatePicker Bug Test")
}
Section {
Text("Selected Dates Count: (selectedDates.count)")
ForEach(Array(selectedDates).sorted(by: {
Calendar.current.date(from: $0)! < Calendar.current.date(from: $1)!
}), id: .self) { dateComponent in
if let date = Calendar.current.date(from: dateComponent) {
Text(date.formatted(date: .long, time: .omitted))
}
}
} header: {
Text("Current State of Selected Dates")
}
}
.navigationTitle("Date Picker Bug")
}
}
}
#Preview {
ContentView()
}
