Im using the ContactPickerViewController with CNContactPickerDelegate to get the contact numbers
func contactPicker(picker: CNContactPickerViewController,
didSelectContacts contacts: [CNContact])
{...}
but when I try to use the search bar to find a contact , the selection box disappear (also if I click on the relevant cell , the contact remain unselected)
thanks for your help!


Looks like its a bug in iOS 9. It has been reported.

You could try using other open source alternatives
EPContactsPicker - https://github.com/ipraba/EPContactsPicker
Or write your own tableview that implements the functionality.
