I've added these to my info.plist:

<key>NSAppleMusicUsageDescription</key>
<string>...</string>

and this's the picker implementation:

class RingtonePickerController(
    private val parent: UIViewController
) : NSObject(), MPMediaPickerControllerDelegateProtocol {

    private var mediaPicker: MPMediaPickerController? = null

    fun showRingtonePicker() {
        mediaPicker = MPMediaPickerController(MPMediaTypeAnyAudio)
        mediaPicker?.delegate = this
        mediaPicker?.allowsPickingMultipleItems = false
        parent.presentViewController(mediaPicker!!, animated = false, completion = null)
    }

    override fun mediaPickerDidCancel(mediaPicker: MPMediaPickerController) {
        mediaPicker.dismissViewControllerAnimated(true, completion = null)
    }

    override fun mediaPicker(mediaPicker: MPMediaPickerController, didPickMediaItems: MPMediaItemCollection) {
        val selectedItems = didPickMediaItems.items()
        // Do something with the selected media items

        mediaPicker.dismissViewControllerAnimated(true, completion = null)
    }
}

it doesn't work tho for some reason? whenever I call the showRingtonePicker method the ui will freeze for a second indicating that something is being pushed in front of my current controller, but then it just goes back to normal with nothing happening

I'm using a single swift uiviewcontroller that has a single child composable uiviewcontroller embedded into it

any ideas? thank you

I've tried using both the uiviewcontrollers as the parent, neither of them worked
