Swift app crashing without any errors? - swift

Question

I have an app in Swift. I have a view controller:
//
// ViewController.swift
// SwiftUIPickerFormatted
//
// Created by Codepixl
// Copyright (c) 2014
//
import UIKit
class FirstViewController: UIViewController,UIPickerViewDataSource,UIPickerViewDelegate,UIAlertViewDelegate {
#IBOutlet weak var chapterPicker: UIPickerView!
let chapterData = [1,2,3,4,5,6,7,8,9,10,11,12,13]
let lessonData = [1,2,3,4,5,6,7,8,9,10]
let classData = ["Pre Algebra","Algebra 1"]
var data = ["ade","01","01"]
override func viewDidLoad() {
super.viewDidLoad()
if(UIApplication.sharedApplication().canOpenURL(NSURL(string:"puffin://")!) == true){
println("Can open Puffin links")
}else{
showPuffinAlert()
}
chapterPicker.delegate = self
chapterPicker.dataSource = self
}
//MARK: - Delegates and datasources
//MARK: Data Sources
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 3
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
if(component == 0){
return classData.count
}else if(component == 1){
return chapterData.count
}else if(component == 2){
return lessonData.count
}
return 1
}
//MARK: Delegates
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String! {
if(component == 0){
return classData[row]
}else if(component == 1){
return "Chapter " + String(chapterData[row])
}else if(component == 2){
return "Lesson " + String(lessonData[row])
}
return "Error!"
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if(component == 0){
if(row == 0){
data[0] = "ade"
}else if(row == 1){
data[0] = "ate"
}
}else if(component == 1 || component == 2){
if(row+1 < 10){
data[component] = "0"+String(row+1)
}else{
data[component] = String(row+1)
}
}
println("puffin://www.phschool.com/webcodes10/index.cfm?wcprefix=\(data[0])&wcsuffix=\(data[1])\(data[2])&area=view")
}
func showPuffinAlert(){
var createAccountErrorAlert: UIAlertView = UIAlertView()
createAccountErrorAlert.delegate = self
createAccountErrorAlert.title = "Oops!"
createAccountErrorAlert.message = "It seems you do not have the Puffin web browser installed, which is required for this app to work. You can go ahead, but be aware the video and textbook links will not work."
createAccountErrorAlert.addButtonWithTitle("I understand- Proceed.")
createAccountErrorAlert.addButtonWithTitle("I'll download Puffin for free.")
createAccountErrorAlert.show()
}
func alertView(View: UIAlertView!, clickedButtonAtIndex buttonIndex: Int){
switch buttonIndex{
case 0:
NSLog("Proceed");
break
case 1:
NSLog("DL");
UIApplication.sharedApplication().openURL(NSURL(string: "https://itunes.apple.com/us/app/puffin-academy/id716707933?mt=8#")!)
break
default:
NSLog("Default");
break
//Some code here..
}
}
#IBAction func GoVideo(sender: AnyObject) {
UIApplication.sharedApplication().openURL(NSURL(string:"puffin://www.phschool.com/webcodes10/index.cfm?wcprefix=\(data[0])&wcsuffix=\(data[1])\(data[2])&area=view")!)
}
}
And all works fine until I hit the "I understand-Proceed" or "I'll download Puffin for free" or the GoVideo button- it crashes with no error. I am completely stumped here as to what is happening...
EDIT: I have also cleared my build folder and manually deleted everything in it as well as adding a println in my app delegate and view controllers to make sure they have updated, and they have. Also the Simulator has been cleared.

There's probably a corrupted file in your Xcode project. Just make a new project and try the code there.
