the problem is that if i simply put a datapicker inside a new project works... if i put datepicker in a form already present (on xib) and i set time wheel, when i scroll the time crash, but in the class there isn't any event of datepicker, only scroll crash (inside the apple library).. the same with ios 17.0 works

if i put datepicker in a form already present (on xib)

Is is an UIKit or SwiftUI project ?

the project is objectc project create on 2013, during the years will be updates but have over 200 views in xib mode, everything works but uipicker crash... is uikit project

i try to create programmatically but the error is the same:

UIDatePicker *datePicker = [[UIDatePicker alloc] init];

datePicker.datePickerMode = UIDatePickerModeDateAndTime;
if (@available(iOS 13.4, *)) {
    [datePicker setPreferredDatePickerStyle:UIDatePickerStyleWheels];
} else {
    // Fallback on earlier versions
}

datePicker.date = [NSDate date];



[self.view addSubview:datePicker];


datePicker.frame = CGRectMake(0, 0, self.view.frame.size.width, 216); // Puoi personalizzare queste dimensioni a tuo piacimento
if (@available(iOS 15.0, *)) {
    datePicker.roundsToMinuteInterval=NO;
} else {
    // Fallback on earlier versions
}

if i put datePicker.datePickerMode = UIDatePickerModeDate; works... the issue is when contant is time

Hi

We have the same issue.

We use UIKit and since iOS17.1 we our app crashes when scrolling on datetime picker , this happens only when using .time or .dateAndTime. On ios17.0.3 and before we don't get this problems.

We got the same error : attempt to insert nil object from objects[0]

Any idea howto solve this issue?

Regards,

i found a possible solution: https://github.com/sumup/sumup-ios-sdk/issues/133

my issue will be solve removing sumup sdk (that i use inside a project)
