Segmentation fault: 11 with swift - ios

Question

I am experimenting with my code to try to add some new features in. After adding in the new UserDefaults I got an error that read "Segmentation fault: 11" and it flagged my secondviewcontoller, the code is down below. Please help
import Foundation
import UIKit
import SpriteKit
import AVFoundation
protocol DestinationViewDelegate {
}
var delegate : GameViewDelegate! = nil
var bombSoundEffect: AVAudioPlayer!
var ghost = SKSpriteNode()
class SecondViewController: UIViewController, GameViewDelegate {
var sw = false
let defaults = UserDefaults.standard
#IBAction func one(_ sender: AnyObject) {
defaults.set(1, forKey: "Sphere")
print("Ghost one was selected")
}
#IBAction func two(_ sender: AnyObject) {
defaults.set(2, forKey: "Sphere")
print("Ghost two was selected")
}
#IBAction func three(_ sender: AnyObject) {
defaults.set(3, forKey: "Sphere")
print("Ghost three was selected")
}
#IBAction func four(_ sender: AnyObject) {
defaults.set(4, forKey: "Sphere")
print("Ghost four was selected")
}
#IBAction func five(_ sender: AnyObject) {
defaults.set(5, forKey: "Sphere")
print("Ghost five was selected")
}
#IBAction func six(_ sender: AnyObject) {
defaults.set(6, forKey: "Sphere")
print("Ghost six was selected")
}
#IBOutlet var mySwitch: UISwitch!
#IBAction func switchpressed(_ sender: AnyObject) {
let defaults = UserDefaults.standard
if mySwitch.isOn{
defaults.set(true, forKey: "SwitchState")
if bombSoundEffect != nil {
bombSoundEffect.stop()
bombSoundEffect = nil
}
}
else{
defaults.set(false, forKey: "SwitchState")
let path = Bundle.main.path(forResource: "Untitled2.wav", ofType:nil)!
let url = URL(fileURLWithPath: path)
do {
let sound = try AVAudioPlayer(contentsOf: url)
bombSoundEffect = sound
sound.numberOfLoops = -1
sound.play()
} catch {
// couldn't load file :(
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Keep this part the same
let defaults = UserDefaults.standard
if (defaults.object(forKey: "SwitchState") != nil) {
mySwitch.isOn = defaults.bool(forKey: "SwitchState")
}
// Check to see if the switch is off, if so, stop the music
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Release any cached data, images, etc that aren't in use.
}
}

The problem is this bit of code:
#IBAction func one(_ sender: AnyObject) {
defaults.set(1, forKey: "Sphere")
print("Ghost one was selected")
}
You've found a compiler bug. Try to work around it like this:
#IBAction func one(_ sender: AnyObject) {
defaults.set(1 as Any, forKey: "Sphere")
print("Ghost one was selected")
}
You will need to do that for all your defaults.set calls. I think that will allow you to compile.
