09/13/2025, 9:07 AMStacktrace shows the following:
1. My Datepicker component gets called
2. rememberDatePickerState() gets created
3. it creates DatePickerStateImpl
4. DatePickerStateImpl needs KotlinxDatetimeCalendarModel
5. KotlinxDatetimeCalendarModel tries to access Clock.System
6. Fails, since kotlinx.datetime.Clock.System doesn't exists on iOS
This is the content of my component, so nothing special in here:
Copy code
val datePickerState = rememberDatePickerState()
if (showDatePicker) {
DatePickerDialog(
onDismissRequest = {
onShowDatePicker(false)
},
confirmButton = {
TextButton(
onClick = {
datePickerState.selectedDateMillis?.let { selectedMillis ->
val selectedDate =
kotlin.time.Instant.Companion.fromEpochMilliseconds(selectedMillis)
.toLocalDateTime(timeZone = TimeZone.currentSystemDefault()).date
onChangeDate(selectedDate)
}
onShowDatePicker(false)
}
) {
Text(
text = stringResource(Res.string.ok),
style = MaterialTheme.typography.labelLarge,
color = MaterialTheme.colorScheme.primary,
)
}
},
dismissButton = {
TextButton(
onClick = {
onShowDatePicker(false)
}
) {
Text(
text = stringResource(Res.string.cancel),
style = MaterialTheme.typography.labelLarge,
color = MaterialTheme.colorScheme.primary,
)
}
},
shape = ScTheme.Shapes.small,
colors = DatePickerDefaults.colors(containerColor = MaterialTheme.colorScheme.surface)
) {
DatePicker(
modifier = Modifier.fillMaxWidth(),
state = datePickerState,
colors = DatePickerDefaults.colors(
containerColor = MaterialTheme.colorScheme.surface,
titleContentColor = MaterialTheme.colorScheme.onSurface,
headlineContentColor = MaterialTheme.colorScheme.onSurface,
selectedDayContainerColor = MaterialTheme.colorScheme.primary,
selectedDayContentColor = MaterialTheme.colorScheme.onPrimary,
todayDateBorderColor = MaterialTheme.colorScheme.primary,
todayContentColor = MaterialTheme.colorScheme.primary,
dayContentColor = MaterialTheme.colorScheme.onSurface,
currentYearContentColor = MaterialTheme.colorScheme.onSurface,
subheadContentColor = MaterialTheme.colorScheme.onSurface,
yearContentColor = MaterialTheme.colorScheme.onSurface,
selectedYearContainerColor = MaterialTheme.colorScheme.primary,
selectedYearContentColor = MaterialTheme.colorScheme.onPrimary,
dayInSelectionRangeContentColor = MaterialTheme.colorScheme.onSurface,
weekdayContentColor = MaterialTheme.colorScheme.onSurface,
disabledDayContentColor = MaterialTheme.colorScheme.onSurface,
disabledSelectedDayContainerColor = MaterialTheme.colorScheme.onSurface,
disabledSelectedDayContentColor = MaterialTheme.colorScheme.onSurface,
dayInSelectionRangeContainerColor = MaterialTheme.colorScheme.onSurface,
),
)

09/14/2025, 9:04 AMActually it is, but I found out with 1.10.0-alpha01 it is fixed.
As you can see here:
