Код в основном представляет собой форму ввода, которая позволяет пользователю вводить несколько текстовых полей.в том числе Text Picker, выбор времени и даты.Приложение случайно падает в разных точках при заполнении полей.

Я прикрепил скриншот формы: IOS App EntryФорма

Это код страницы: 

public NewItemPage(NewItemEViewModel viewModel)
{

    Item = new Item
    {
        Id = viewModel.Itemstatus.Id,
        Text = viewModel.Itemstatus.Text,
        DateOfBirth = viewModel.Itemstatus.DateOfBirth,
        Gender = viewModel.Itemstatus.Gender,
        DeviceID = viewModel.Itemstatus.DeviceID,
        PMobile = viewModel.Itemstatus.PMobile,
        CMobile = viewModel.Itemstatus.CMobile,
        MedicationTime = viewModel.Itemstatus.MedicationTime,
        Message = viewModel.Itemstatus.Message,
        EnableAlarm = viewModel.Itemstatus.EnableAlarm,
        EnableReminderP = viewModel.Itemstatus.EnableReminderP,
        EnableReminderC = viewModel.Itemstatus.EnableReminderC,
        TimeZone = viewModel.Itemstatus.TimeZone,
        Notes = viewModel.Itemstatus.Notes,
        IntCodeP = viewModel.Itemstatus.IntCodeP,
        IntCodeC = viewModel.Itemstatus.IntCodeC
    };

    if (viewModel.Itemstatus.DeviceID == "No Device Linked") viewModel.Itemstatus.ButTxt = "Link Device "; else viewModel.Itemstatus.ButTxt = " Unlink Device ";

    InitializeComponent();
    BindingContext = this.viewModel = viewModel;

    PickerCtl.SelectedIndex = viewModel.Itemstatus.TimezoneIndex;
    PickerCtlGender.SelectedIndex = viewModel.Itemstatus.GenderIndex;
    PickerCtlIntCodeP.SelectedIndex = viewModel.Itemstatus.IntCodePIndex;
    PickerCtlIntCodeC.SelectedIndex = viewModel.Itemstatus.IntCodeCIndex;

    DateCtl.Date = viewModel.Itemstatus.DateOfBirth;
    DateCtl.MaximumDate = System.DateTime.Now.Date;

}

Попробовав абсолютно все, я заменил кнопки (переключатели) на сборщики предметов.Это остановило случайное падение приложения.

Я не уверен, почему кнопки / переключатели вызывают нестабильность.
