IOS Emulator doesn't appear with latest Meteor version

Hello,
I updated my Meteor project with latest versions.

When I run “meteor run ios”, everything sounds good but the ios emulator doesn’t appear.
It was Ok before the update.
Any idea?

Thanks,
Olivier.

The trace after “meteor run ios” is:
=> Started proxy.
=> Started app on iOS Simulator.
=> Started MongoDB.
=> Started your app.

=> App running at: http://localhost:3000/

Well, I had to update Xcode to the latest version too. I was in version 5 and after an update to the latest version (6.3), it works well with an iPhone 6 emulator by default.
