ios - Contacts framework doesn't request for access when needed -

this have far:

private let contactstore = cncontactstore()  private func requestaccessforcontacts() {      switch cncontactstore.authorizationstatusforentitytype(.contacts) {     case .denied, .notdetermined:          contactstore.requestaccessforentitytype(.contacts, completionhandler: { access, error in              if access {                 print("super")             } else {                 print("problem")             }         })     case .authorized:         print("ok")     case .restricted:         print("restricted")     } } 

the problem printed on console, nothing displayed on screen, no request access. why?

your code works; able replicate problem first rejecting access contact , re-running app.

once have disallowed access, subsequent running of app log "problem" without displaying request window.

if 1 wanted see request window again after denying, 1 could, however, go "settings" -> "reset" , click "reset location , privacy" in simulator.

after having done so, next time run app, request window pop again.
