Whenever I run this code, after I have purchased something and it shifts up after leaving and reopening the page it crashes with the error "Index out of range". Code - https://developer.apple.com/forums/content/attachment/86665b01-4c50-47bd-a14d-ef95b58db511 Ideas? Thanks in advance! Ps: I can provide full project if needed.
