title: Property does not exist on type
body: <p>I am working on a project with Ionic2 and Angular2. When trying to run <code>ionic serve</code>, the data is retrieved without any errors. However, when trying to test on ios and running <code>ionic build ios</code>, I am getting the below compile time errors, that properties do not exist.</p>
  
  <p>Has anyone else encountered this issue? </p>
  
  <p>I appreciate any suggestions. </p>
  
  <p>home.ts</p>
  
  <pre><code>import { Component } from '@angular/core';
  import { ProfileService } from './profile.service';
  
  @Component({
      selector: 'home',
      templateUrl: 'home.html',
      providers: [ProfileService]
  })
  export class HomePage {
  
      constructor(public d: HomeService){
          this.loadData();
      }
  
      loadData() {
       this.d.fbPromise.then( (FB) =&gt;    this.data.getData(FB)).then(response =&gt; {
           this.data = response;
       });
     }
  }
