Answer 1

Working form with my ionic 3 App:

import {FormBuilder, FormGroup, Validators  } from '@angular/forms';


@IonicPage()
@Component({
  selector: 'page-mobile-login',
  templateUrl: 'mobile-login.html',
})
export class MobileLoginPage {
    public loginForm:FormGroup;

    constructor(public navCtrl: NavController, 
      public navParams: NavParams,
      public formBuilder: FormBuilder) 
      {
          this.loginForm = formBuilder.group({
              mobile: ['', Validators.compose([Validators.required,Validators.pattern('[0-9 ]*'),
                Validators.maxLength(10),Validators.minLength(10)])]
            });
      }


}

Seems issue you are using another function setForm() in constructor.

mobile-login.html

  
    
      
      
    
    
      

        Enter Valid Mobile Number
      
    
  

    
      
        
        
            Submit
