How to fix "This decoder will only decode classes that adopt NSSecureCoding. Class 'UIImageView' does not adopt it."

I am trying to archive my UIImageView which contains many CaLayers and Views.

I am successfully saved 'UIImageView' as Data through below code..

        let data = try? NSKeyedArchiver.archivedData(withRootObject: self.backgroundIV!, requiringSecureCoding: false)
        print(data)

When I try to un-archived UIImageView form Data via below code.

do {
            let imageView: UIImageView = try NSKeyedUnarchiver.unarchivedObject(ofClass: UIImageView.self, from: data!)!
            self.backgroundIV = imageView
            print("Un Archived...")
        } catch {
            print(error)
        }
   }

I got this error..

Optional(922 bytes)
Error Domain=NSCocoaErrorDomain Code=4864 "This decoder will only decode classes that adopt NSSecureCoding. Class 'UIImageView' does not adopt it." UserInfo={NSDebugDescription=This decoder will only decode classes that adopt NSSecureCoding. Class 'UIImageView' does not adopt it.

Generally, I'd suggest archiving the input data of your UIImageView rather than the image view itself. Regardless, here's how to unarchive using NSKeyedUnarchiver with classes that don't adopt NSSecureCoding:

do {
    let data = try Data(contentsOf: someURL)
            
    let unarchiver = try NSKeyedUnarchiver(forReadingFrom: data)
    unarchiver.requiresSecureCoding = false
    let imageView = try unarchiver.decodeTopLevelObject(of: UIImageView.self, forKey: NSKeyedArchiveRootObjectKey)
    unarchiver.finishDecoding()

    return imageView
} catch {
    return nil
}
