How do I pay my SWIFT account?

I'm a bit confused about how to pay into my SWIFT account. Could you please clarify the process for me? Do I need to use a specific bank or payment method? Are there any fees associated with making a payment into a SWIFT account? I'd also like to know if there are any security measures in place to protect my funds when making a payment. Lastly, how long does it typically take for a payment to be processed and credited to my SWIFT account?
