There are two extremely vague claimed records of the Swallowtail in Nottinghamshire. Both date back to sometime in the 1800's and were included in Carr's book 'The Invertebrate Fauna of Nottinghamshire. Nottingham: J.& H. Bell Ltd (1916)'  with Carr writing 'William Howitt, in 'The Book of the Seasons' states that the Swallowtail was 'once taken at Newark-on-Trent and at Welbeck'. Carr adds that 'assuming the statement to be correct, the specimens were presumably imported'.

Livestock of the continental form 'gorganus' is readily available through a number of entomological suppliers and any Nottinghamshire Swallowtail records  are almost certainly due to be the result of captive escapes and releases. There was certainly a known release of a number of second brood adults in Blidworth in 2019 and also a single seen and photographed in a Shelford garden on 29/07/19 (per John Benyon), so more are likely to occur.
