Rules:
Standard - Normal Sudoku rules apply
Arrow - Digits along an arrow sum to the digit in that arrow’s circle. Digits can repeat along an arrow if allowed by other rules.
Killer Cage - Digits in a killer cage must sum to the small clue in the top left corner of the cage. Digits cannot repeat within a cage.
White Dot - Pairs of digits with white dots in between are consecutive. Not all white dots are necessarily given
Special Constraint - In this puzzle, there exists a pair of digits where, if you were to swap all the final positions of the two digits in the finished grid, the puzzle would still reach a solution which satisfies the conditions set by all other clues. The special pair of digits (the swappable digit pair) is two distinct digits which add to 10. The swappable digit pair is a discoverable, persistent and necessary component for solving this puzzle.

This is my first puzzle, please be kind :)
Lösungscode: Enter the digits from column 9 from top to bottom, as well as the two digits of the swappable digit pair in ascending order (no spaces).

That was lovely, congratulations on setting such a nice, interesting puzzle! At first I was a bit puzzled what was meant by 'all other clues', but soon I understood what was the idea. Thank you for sharing!
