getting contacts in swift 3 not working - swift3

Question

I'm trying to get contacts (swift 3) in ios 9
func getInnerContacts()-> Observable<[CNContact]>{
return Observable<[CNContact]>.create({ (observer) -> Disposable in
var contacts = [CNContact]()
let keysToFetch = [CNContactFormatter.descriptorForRequiredKeys(for: .fullName), CNContactPhoneNumbersKey] as [Any]
self.contactStore.requestAccess(for: .contacts, completionHandler: { (granted, error) -> Void in
if granted {
let predicate = CNContact.predicateForContactsInContainer(withIdentifier: self.contactStore.defaultContainerIdentifier())
do {
contacts = try self.contactStore.unifiedContacts(matching: predicate, keysToFetch: keysToFetch as! [CNKeyDescriptor])
contacts = newContacts.filter({ (contact) -> Bool in
return !contact.phoneNumbers.isEmpty && contact.givenName != "" || !contact.phoneNumbers.isEmpty && contact.familyName != ""
})
observer.onNext(contacts)
observer.onCompleted()
}catch {
observer.onError(error)
}
}
})
return Disposables.create()
})
}
but it doesn't work, moreover, I can't see permission alert.
Before executing i first check the iOS version, like this:
if #available(iOS 10 , *){
}else if #available(iOS 9, *){
}
then i added permission tag Privacy - Contacts Usage Description into Info.plist file. This works fine in ios 10, any ideas how can I achieve this in ios 9

It will work fine in Swift 3.
var store = CNContactStore()
var contacts = [CNContact]()
Try this in viewDidLoad():
let keysToFetch = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey, CNContactEmailAddressesKey, CNContactOrganizationNameKey, CNContactImageDataKey]
let request = CNContactFetchRequest(keysToFetch: keysToFetch as [CNKeyDescriptor])
do {
try self.store.enumerateContacts(with: request) { contact, stop in
self.contacts.append(contact)
}
DispatchQueue.main.async(execute: {
for contact in self.contacts {
print("contact:\(contact)")
let firstName=String(format:"%#",contact.givenName)
// print("first:\(firstName)")
self.givenNameArray.append(firstName)
let lastName=String(format:"%#",contact.familyName)
// print("last:\(lastName)")
self.familyNameArray.append(lastName)
let comapny=String(format:"%#",contact.organizationName)
// print("company:\(comapny)")
self.organizationNameArray.append(comapny)
//get all phone numbers
// for ContctNumVar: CNLabeledValue in contact.phoneNumbers
// {
// let MobNumVar = (ContctNumVar.value ).value(forKey: "digits") as? String
// print("ph no:\(MobNumVar!)")
// get one phone number
let MobNumVar = (contact.phoneNumbers[0].value ).value(forKey: "digits") as! String
// print("mob no:\(MobNumVar)")
self.phonenosArray.append(MobNumVar)
// get all emails
// for ContctNumVar1: CNLabeledValue in contact.emailAddresses
// {
// print("email \(ContctNumVar1.value(forKey: "value") as! String)")
// }
// get one email
let email = (contact.emailAddresses[0]).value(forKey: "value") as! String
// print("email:\(email)")
self.emailsArray.append(email)
let imagedat=contact.imageData
// print("image data:\(imagedat)")
let image=UIImage(data: imagedat!)
// print("image:\(image)")
self.imagesArray.append(image!)
}
})
} catch {
print(error)
}
