Current behavior:
On iOS 11 Beta fetching contacts block UI.
The issue reproduces on iPhone 6S and iPhone 7 Plus.

Expected behavior:
Fetching contacts should not block UI as on iOS 10.

Steps to reproduce:
Try import 5K contacts, during that period UI frozen.

Related code:

Injectable()
export class ImportPhonebookContact {
  importProcessed: boolean = false;

  constructor(private contacts: Contacts,
              private http: Http) {}

  import(): Promise<boolean> {
    if(this.importProcessed) {
      return Promise.resolve(this.importProcessed);
    } else {
      this.importProcessed = true;
    }
    console.time("Fetch contacts")
    return new Promise(resolve => {
      this.contacts.find(['displayName', 'phoneNumbers'], {
        multiple: true
      }).then(contacts => { 
        console.timeEnd("Fetch contacts")
        this.remoteExport(contacts);
        resolve(this.importProcessed);
      }).catch(console.log);
    });
  }

  private remoteExport(connections: Contact[]): void {
    const headers = new Headers();
    headers.append('Authorization', 'Bearer ' + localStorage.getItem('accessToken'));

    this.http.post(APP_CONFIG.apiUri + '/sync/phonebook', 
                   { connections: connections }, 
                   { headers }).toPromise();
  }
}
