How to install older iOS runtimes on newer Xcode?

I have Xcode 10.3

I wish to run an iPad Mini simulator running iOS 9.0.3

However when I go to Preferences > Components the only options are:

iOS 12.2 Simulator
iOS 12.1 Simulator
iOS 12.0 Simulator
iOS 11.4 Simulator
iOS 11.3 Simulator
iOS 11.2 Simulator
iOS 11.1 Simulator
iOS 11.0 Simulator
iOS 10.3.1 Simulator

There is no 9.0.3. How do I download older simulators?

How do I use an older iOS simulator?

To run an older iOS simulator, you must choose an older iOS version in the "iOS Deployment Target" build setting popup. Only then will the "Overview" popup offer older Simulators: back to 4.0 for iPhone and to 3.2 for iPad.

Xcode supports SDK latest three versions of the iOS SDK. The only way to have an access to older simulators is to install older version of Xcode.
