I'm about to publish an app on the app store, and I'm looking to set the minimum OS version as it appears in iTunes as "Requires iPhone OS 3.x or later". 2 questions:
1) Where do I set this in my Xcode project?
2) I'm aware of the UITableViewCell numberOfLines property that is present only in OS > 3.1. If I set my minimum as OS 3.0, will people who have 3.1 be able to see the number of lines properly as I coded? (Obviously people on 3.0 won't be able to)
Thanks.

Nonetheless, you should be supporting iOS 6 by now and aspiring to support iOS 7 (if you aren't already). Overall, no matter what your scenario is, I highly recommend that you only support the latest two versions. Supporting the latest three iOS versions would only be necessary on the brink of a new iOS release.
To find the software version installed on your device, go to Settings > General, then tap About.
That is the iOS deployment target or the minimum deployment target for iOS. It means that the application runs on any iOS device with iOS 14.3 or later installed. The values the dropdown menu lists depend on the version of Xcode you are using. Xcode 12, for example, no longer supports iOS 8.
What you need to do is change the Deployment Target setting in your project. The Deployment Target specifies the minimum OS you would like your application to run on. This is regardless of the SDK you build against, which should always be the most recent SDK so you can ensure your application runs correctly on the most recent OS version available. So, in short:
To answer your second question, if you set the Deployment Target to 3.0 your 3.1-only code will no longer compile. There are workarounds to that problem, however.
