command line compilation with Swift 2.0 targeting OS=8.3

I currently compile swift 2.0 with this:


PLATFORM = 'platform=iOS Simulator,name=iPhone 6,OS=9.0'

xcodebuild test -project $(PROJECT).xcodeproj -scheme $(PROJECT) -destination $(PLATFORM)


but my customer is asking if I can complete back to OS=8.3. I set the Deployment target to 8.3 but when change my makefile to OS=8.3 it hangs for a while, then says it's "Unable to find a destination matching the provided destion specifier:...".


Is it just looking for a compatible simulator or is this a larger problem?
