Synonym discussion
Sense: verb/1
All four words involve giving or receiving something in return. 'Swap' is the most informal and conversational — it describes a direct, mutual exchange between two people where each gives and receives simultaneously, with no money necessarily involved. 'Exchange' is the formal equivalent and works in many contexts ('exchange rings', 'exchange contracts'). 'Trade' often implies bargaining or a commercial context ('trade in your car'), but can overlap with swap in casual use ('trade stickers'). 'Switch' focuses on changing positions or roles rather than objects ('switch seats'). 'Barter' is the most specific — it means exchanging goods or services without using money, typically in a system or economy where currency is not used. For everyday giving-and-receiving, 'swap' is the most natural choice: 'Let's swap phones for a day' sounds natural, while 'Let's barter phones' sounds odd.

Etymology
The word 'swap' originally meant 'to strike' in Middle English (from swappen). The exchange meaning developed from the old practice of striking hands together to seal a bargain — the physical gesture of a handshake confirming a deal became the word for the deal itself. By the 14th century it had shifted to mean 'to exchange', and it has stayed in everyday use ever since.
