Which banks support SWIFT?

If I'm looking to find out which banks support SWIFT, what are some of the main factors I should consider? Are there any specific regions or types of banks that are more likely to offer SWIFT support? And how can I verify if a particular bank does indeed offer SWIFT services? Additionally, are there any fees or limitations associated with using SWIFT that I should be aware of? Finally, is SWIFT still considered a reliable and secure method for international bank transfers in today's digital age?
