On Catalina, how to add an iOS 9.3 simulator ?
You need to install an Xcode version that supports iOS 9.0 simulator, like Xcode 10.2.1 and download and install the iOS 9 simulator in preferences.
Catalina supports iOS 10.3 and later simulator runtimes. If you need to test with iOS 9.x simulator runtimes, you will need to remain on Mojave.
