Similar things in other languages!:

Greek's Podaná: https://en.m.wikipedia.org/wiki/Podan%C3%A1

Rioplatense Spanish's Vesre: https://en.m.wikipedia.org/wiki/Vesre

Serbo-Croatian's Šatrovački: https://en.m.wikipedia.org/wiki/%C5%A0atrova%C4%8Dki

(Please let me know if I missed any.)

Here for completion but not really the same if you ask me:

English's Back Slang https://en.m.wikipedia.org/wiki/Back_slang and Australian "Butchers' Talk" https://www.smh.com.au/entertainment/movies/behind-that-tray...

Bernese German has a similar thing, however they don't swap syllables, they move the initial consonant cluster to the end of the word, and add vowels, like this:

Schnure -> Ire-schnee
