I have multiple versions of Xcode installed. I can build my project against older iOS versions by launching old Xcode. But how could I use newer Xcode versions to build against older iOS versions?
In the project settings there's a Base SDK dropdown. It only offers the very latest iOS version for selection.
Under /Developer/Platforms/ there is an iOS.platform folder which contains this:
SDKs/ iPhoneOS3.2.sdk iPhoneOS4.1.sdk And finally, there is an interesting folder called DeviceSupport, which contains a whole bunch of versions ranging from 3.0 to 4.1!
There must be a way to copy SDKs / DeviceSupport files from old Xcode to new Xcode and make the older ones like iOS 4.0 or even 3.0 working. How?

Go into contents/Developer/platform/iPhoneOS. platform/DeviceSupport. Copy your previous iOS 14.5 the device support file or older version. Paste into the same folder and change the iOS number to 14.6.
The signature generated by a build with XCode 12.4 or lower on a Mac running with Mac OS 10.14 or lower are invalid with iOS 15.
New FeaturesThe compiler supports this flag with deployment targets of macOS 11, iOS and iPadOS 14, tvOS 14, watchOS 7 and later. The flag is enabled by default.
To make an application target that runs on multiple versions of iOS is relatively simple: Set the “Base SDK” in your projects settings to the newest version number of iOS whose features you may want. Set the “iPhone OS Deployment Target” to the oldest version number of iOS that you will support
you will need to install older versions of xcode since the newer simulator will only support the newer ios versions
