iOS Simulators missing when deployment target set to 8.3

Question

I'm still new to Xcode, but I've recently run into an issue that has me stumped. As best as I can tell, right after I updated to 10.10.3, and to Xcode 6.3, any new projects I create don't have an iOS Simulators available. If I change the Deployment Target back to 8.2 (from 8.3), they are once again available. But as long as I leave it set to a deployment target of 8.3, I can only see "iOS Device" and no iOS Simulators are listed.

I've tried deleting and reinstalling Xcode, but I'm still ending up with the same results. Anyone else having this issue, and or know of a fix for this?

I had a similar problem as the original poster (Bill Matthews). On my MacPro (Early 09), but not my MacBookAir - both running 10.10.3 and newly installed Xcode 8.3 (over the beta 3 version) - I could not get any simulators to show up, irrespective of the iOS build target. (The temporary workaround was debugging on a real device, after selecting it from the "Product" menu -> "Destination"->"Ineligible Devices"->{my iPhone}.)

I tried deleting the simulators in ~/Library/Developer, but could not reinstall them; the Preferences->Downloads->Components would show them as installed/checked off, even after reboot, despite being deleted. Same result even after deleting the components folder and ~/Library/Caches/com.apple.dt.Xcode/Downloads and reboot. Same result even after deleting all of ~/Library/Developer, unlike Bill Matthews (Mazel Tov!).

In an abundance of caution, I reinstalled 10.10.3 from the combo updater (not AppStore), then Xcode 8.3 from developer.apple.com (not AppStore).

That did the trick for me. YMMV.
