Ionic Storage dont work DEVAPP IOS

#1

I’m using ionic storage to save some login, user and token data, but testing on the web browser works fine, now when I’m using DEVAPP it only works on android, on the iphone it hangs up the device.
Has anyone ever experienced this??
thank you

if (retornoAPI.Codigo == '0') {
          this.storage.set('dadosUsuario', retornoAPI.Objeto ).then( () => {
            this.navCtrl.setRoot(HomePage);
          },
            error => alert('Problemas ao efetuar login.')
          );
