Many of Apple's tutorials on SwiftData are written alongside SwiftUI, including the sample code.
Would it be a bad idea to use SwiftData separately? If I don't use SwiftUI, would it be wiser to choose a different database instead?
Is SwiftData created specifically for SwiftUI?
I found this example https://www.hackingwithswift.com/quick-start/swiftdata/how-to-use-swiftdata-with-uikit
No, SwiftData can be used with UIKit for instance, not requiring SwiftUI.
