I'm working on converting vcard to cncontact.
I'm using CNContactVCardSerialization.contacts(with data: Data).
However, when I tried to import 4000 contacts using that method, I was only able to import 450.
The debug console displays:
Incorrect NSStringEncoding value 0x0 detected. Assuming NSASCIIStringEncoding.
A warning appears saying:
Will stop this compatibility mapping behavior in the near future.
Perhaps there are incorrect characters in the string saved in the contacts. So I want to remove the contacts that are causing the error.
Is it possible to remove incorrect encoding from data converted to NSData format?
I don't know if I can remove the incorrect encoding using the drop(while:) function after changing NSData to Data.
