Errors in build for IOS

I just build a very simple app based on meteor-ionic-angular using this official whatsapp tutorial:

Upto this step:

I am using the latest version of meteor i.e Meteor
Also patched using meteor update --patch

Now when I run my app for ios using this command:

meteor run ios-device

It opens my code in Xcode and when I run the build, it gives too many errors:

My XCode version is: 7.3.1

It works perfect for android. But for IOS I get all these errors.

Is there any workaround to fix these errors?

Isn’t that version of Xcode a bit old?

Do you think that its due to the older version of Xcode?
