如何将MKMapItem转换成二进制数据存储在核心数据中？

import CoreData

@NSManaged var binaryData: Data?

func convertToBinaryData(mapItem: MKMapItem) -> Data? {
    do {
        let archivedData = try NSKeyedArchiver.archivedData(withRootObject: mapItem, requiringSecureCoding: false)
        return archivedData
    } catch {
        print("Failed to convert MKMapItem to binary data: \(error)")
        return nil
    }
}

let mapItemData = MapItemData(context: managedObjectContext)
if let binaryData = convertToBinaryData(mapItem: mapItem) {
    mapItemData.binaryData = binaryData
}

do {
    try managedObjectContext.save()
} catch {
    print("Failed to save MapItemData: \(error)")
}
