What is the difference between Swift and FIX?

Could you please explain the fundamental differences between Swift and FIX? I understand that both are widely used in the financial industry, but I'm curious about the specific scenarios where one would be preferred over the other. Swift, for example, is often associated with international payments and transfers, while FIX is known for its role in electronic trading. Can you elaborate on these differences and provide any real-world examples to illustrate their applications?
