Why did I get an error in playground in debug window for this code?
print("// MARK: - Start execable code here...")
do {
let store = CNContactStore()
if try await store.requestAccess(for: .contacts) {
// Do something with Contacts.
let phoneNumber = CNPhoneNumber(stringValue: "903-276-1046")
let predicateForContactsMatchingPhoneNumber = CNContact.predicateForContacts(matching: phoneNumber)
let contactFetchRequest = CNContactFetchRequest(keysToFetch: thoroughKeysToCompare)
contactFetchRequest.predicate = predicateForContactsMatchingPhoneNumber
contactFetchRequest.unifyResults = true
var contactOfMe: CNContact! = nil
try! store.enumerateContacts(with: contactFetchRequest) {
contact, stop in
contactOfMe = contact
stop.pointee = true
}
let contact = Contact(cnContact: contactOfMe)
for property in contact.enumerated() {
print("- \(property)")
}
} else {
// Handle if Contacts access is denied.
fatalError()
}
} catch {
// Handle any error.
print("error requesting access: \(error.localizedDescription)")
}
Debug window:
// MARK: - Start execable code here...
