iPhone 7 does not support haptic feedback?

We are using the following code to check for the haptics support on the device

import CoreHaptics

let hapticCapability = CHHapticEngine.capabilitiesForHardware()
let supportsHaptics: Bool = hapticCapability.supportsHaptics

For some reason it returns false on iPhone 7 not only on my personal device (iOS 13) but some of our users reported the haptic settings missing from our app on iPhones 7 (iOS 15) as well.

I have just checked with this private api call that in fact the devices does support haptics (obviously, it has not physical home button)

extension UIDevice {
    var feedbackSupportLevel: Int? {
        value(forKey: "_feedbackSupportLevel") as? Int
    }
}

let supportsHaptics: Bool = UIDevice.current.feedbackSupportLevel == 2

And it returns true, as expected.

Weird thing is that the haptics work perfectly fine, it's just the haptics support status is incorrect.

So my question is: will we be rejected for checking the value of the _feedbackSupportLevel on UIDevice just to make sure we are correctly displaying available system features for our users on all of the devices?

Sorry, it may be late... but I wanted to add it's perfectly normal that, when running on an iPhone 7, the CHHapticEngine.capabilitiesForHardware() API returns false. The iPhone 7 has a built-in haptic engine but it's not accessible by the Core Haptics APIs. Like Apple said in a WWDC video, Core Haptics in supported by the iPhones 8 / X and later.

I'm also experiencing the same issue on my personal iPhone 7 Plus device as well.

I'm assuming this has to be an issue with the CoreHaptics framework? I'll continue to use the private API in the meantime, I guess.
