Same Problem happened with me.. When I updated from Xcode 8 Beta 3 to Xcode 8 Beta 4, But I resolved it by this way..

1. Go to Window -> Devices

you can see all Devices and Simulators here

2. Just right click on any device or simulator
3. Tick on Show in Destination Menu (Even it is already checked, then click it twice, It may be refresh things)

If above does not work.. as if you do not see any simulators, then..

1. Change(degrade) the minimum deployment target of app to 8.3(not necessary)
2. restart xcode

It worked for me.. Hope will be helpful for someone later..
