How do you change ios sims?

I have Xcode Version 7.0.1 (7A1001), with simulators 8.3, 8.4, and 9.0 installed. When I build to simulator in corona, it goes to 8.3 only. How do I build to the ios 9 sim? I must be asking the wrong questions on google b/c I cannot find anything…

**update** I did get ios 9 sim to open when I changed my skin to iphone 6, but for some reason when I had it on 5s it opens 8.3 sim. there should be an option when you build to select which sim to install to :slight_smile:

corona sdk 2729
