Image is nil while I'm trying to rotate it

So, i am making an app in which you enter coordinates, confirm them, and then an arrow pops up that shows the direction to the place which coordinates user entered. However when i click confirm, the arrow shows up but doesnt rotate. When i tried some troubleshooting, i found out that arrowImageView is nil. Can anyone please help?
