Describe the Bug platform.is('ios') return false on ios when deployed as app while return true when running inside Ionic DevApp. Creating a new App cannot reproduce this behaviour, the bug exists on my current app with several ionic-native plugins.

Steps to Reproduce Steps to reproduce the behavior:

1. create an App
2. put the following code in the MyApp constructor
3. deploy on different platforms

4. collect results:

   On Chrome:

   • platform: mobile: true
   • platform: ios: true
   • platform: iphone: true
   • platform: mobileweb: true

On an Android phone:

• platform: cordova: true
• platform: mobile: true
• platform: android: true

On an iOS - iPhone phone:

• platform: cordova: true
• platform: core: true

On Ionic DevApp (android)

• platform: cordova: true
• platform: mobile: true
• platform: android: true

On Ionic DevApp (ios - iphone)

• platform: cordova: true
• platform: mobile: true
• platform: ios: true
• platform: iphone: true

export class MyApp {
  rootPage: any = HomePage;

  constructor(platform: Platform,
              statusBar: StatusBar,
              splashScreen: SplashScreen) {

    platform.ready().then((source) => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.
      statusBar.styleDefault();
      splashScreen.hide();

      this.printPlatformList(platform);
    });
  }

  private printPlatformList(platform: Platform) {
    let platformList: string[] = platform.platforms();
    for (let i = 0; i < platformList.length; i++) {
      console.log('platform: ' + platformList[i] + ': ' + platform.is(platformList[i]));
    }
  }
}

Thank you for the issue! I am going to close this issue and merge it into #15165 to keep all platform issues in one.
