@satishbabariya & @vvit
I found findDuplicateContacts method in document but not in source file. Can you please add that method if missing?

@mitesh-iosdev, try this old code, it may work.

public func findDuplicateContacts(Contacts contacts : [CNContact], completionHandler : @escaping (_ result : [Array<CNContact>]) -> ()){
    
    let arrfullNames : [String?] = contacts.map{CNContactFormatter.string(from: $0, style: .fullName)}
    var contactGroupedByDuplicated : [Array<CNContact>] = [Array<CNContact>]()
    if let fullNames : [String] = arrfullNames as? [String]{
        let uniqueArray = Array(Set(fullNames))
        var contactGroupedByUnique = [Array<CNContact>]()
        for fullName in uniqueArray {
            let group = contacts.filter {
                CNContactFormatter.string(from: $0, style: .fullName) == fullName
            }
            contactGroupedByUnique.append(group)
        }
        for items in contactGroupedByUnique{
            if items.count > 1 {
                contactGroupedByDuplicated.append(items)
            }
        }
    }
    completionHandler(contactGroupedByDuplicated)
   }
