NSKeyedUnarchiver.unarchivedObject()

‘unarchiveTopLevelObjectWithData’ was deprecated in iOS 12.0: Use unarchivedObject(ofClass:from:) instead

[general] *** -[NSKeyedUnarchiver validateAllowedClass:forKey:] allowed unarchiving safe plist type ''NSNumber' (0x1b9e88aa0)
  [/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/Foundation.framework]'
  for key 'root', even though it was not explicitly included in the client allowed classes set:
  '{(
    "'NSData' (0x1b9e74490) [/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/CoreFoundation.framework]"
  )}'
  This will be disallowed in the future.
