My ionic 3 app is locking on the Splash Screen screen in IOS

initializeApp() {
   this.platform.ready().then(() => {
     this.config.set('', 'backButtonText', '');
     this.statusBar.styleDefault();
     if (this.platform.is('android')) {
       this.statusBar.overlaysWebView(false);
       this.statusBar.backgroundColorByHexString('#000000');
   }
     this.initBackButton();
    });
 }

 ngAfterViewInit(): void {
   this.splashScreen.hide();
 }

 openHome() {
   this.nav.popToRoot();
 }
