Receiving Thread 1 error related to IF statement

Question

I understand this is a common error but I can't figure out why I am receiving it: Thread 1 EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0) :

Is there something specifically wrong with my code? To give some context the code is trying to determine if a particular item is on special and if it is then it strikes out the item's previous price that is displayed in the view controller.

Answer 1

You need to make sure globalVariable.previous and globalVariable.specialBool have the same count. Otherwise, the access to globalVariable.specialBool will crash.

Additionally, while i <= xxxx probably needs to be changed to while i < xxxx because array index is zero based.
