I am an inventor, apps are totally different! I need help from someone kind please. I am trying to change the scene after my game hits max score. To a scene named NewScene here is the code for GameScene, GameView Controller and NewScene. I get the error on NewScene the error is "if let cookie2 = level!.cookieAtColumn2(column, row: row){" Stating EXC_BAD_INSTRUCTION (code = EXC_I386_INVOP, subcode = 0x0) is this because i created a cookie2.swift file and linked the cookie to cookie2 instead? same with cookieAtColumn? Because the error was still appearing before i changed from cookie to cookie2.. I really have no idea why it is this difficult to start a new level. After game over ends it shows the LevelComplete button but then invokes the code ^^-EXC_BAD_INS.... If anyone has any knowledge or understanding on swift xcode please give input, any advice will be greatly valued. My email is also jackcoyle23@yahoo.com if need be.
Here's the code;

You're not going to get a helpful answer because you posted too much code (people won't bother to wade through it), and because you don't show evidence of having tried to at least narrow down the problem (people won't write your app for you).
>> the error is "if let cookie2 = level!.cookieAtColumn2(column, row: row){" Stating EXC_BAD_INSTRUCTION (code = EXC_I386_INVOP, subcode = 0x0)
The "bad instruction" error in Swift apps often just means that your app is being forced to crash. This can happen, for example, when you force-uwrap an optional variable that's nil. In this case, therefore, I'd start looking at whether the "level" variable might be nil.
