You're correct to use gpart(8) to create your new swap partition. Don't use bsdlabel(8) -- that is for dealing with the really old style of disk partitioning and is incompatible with the gpt disk labels you have. Now, in order to fix your problem: you can't change the type of a partition. Instead, you need to delete the partition and then create a new 'freebsd-swap' partition using the same chunk of disk space. Try and quiesce the system as much as possible before you do this -- it might be worth booting from a LiveCD. Also the index numbers look pretty strange to me. Possibly the OS that created those partitions has different ideas on the layout of a gpt partition table, and it might be necessary to boot back into that OS in order to remove the partition cleanly. There's no formatting required for a swap area: the system just uses it as a blob of available space and writes what it needs to.
