If you are having problems swallowing I can recommend that you blend fruits that you like, specifically bananas, with ice cream and milk in a blender. Put them in a short glass with a straw that has been cut down with scissors to make the sucking easier. Ensure is also a good source of nutrients. Of course when swallowing is a big problem there is always the option of a feeding tube which is not as bad as it sounds, all things considered. Mashed potatoes or any other foods that are soft and easy to swallow would be fine.
Nectars are also good and easier to swallow than thinner liquids.
By using a straw and keeping your chin down while swallowing makes the process easier.
