I'm trying to pass the boolean value of a UISwitch to another class using NSUserDefaults. For some reason, in the class that contains the switches, the if statements that are supposed to set the value to NSUserDefaults cannot read the switch declarations.
@IBOutlet var shrimpSwitch: UISwitch!
@IBOutlet var nutSwitch: UISwitch!
@IBOutlet var dairySwitch: UISwitch!
let switchState = NSUserDefaults.standardUserDefaults()
if shrimpSwitch.switch.on{
switchState.setBool(true, forKey: "shrimpSwitch")
}
else{
switchState.setBool(false, forKey: "shrimpSwitch")
}
if nutSwitch.on{
switchState.setBool(true, forKey: "nutSwitch")
}
else{
switchState.setBool(false, forKey: "nutSwitch")
}
if dairySwitch.on{
switchState.setBool(true, forKey: "dairySwitch")
}
else{
switchState.setBool(false, forKey: "dairySwitch")
}
In the first If statement(shrimpSwitch.on), it will say Expected Declaration. Am I declaring the switches all wrong? Any help would be appreciated. Thanks

Here, we will learn why an error expected declaration or statement at end of input is occurred and how to fix it? The main cause of this error is – missing closing curly brace (}) of the main() block. How to fix? To fix this and such errors, please take care of curly braces, they are properly opened and closed.
The Swift compiler is written mostly in C++, and this won't change in the near future. You can extend the standard library using Swift, but if you want to contribute a new language feature or some optimization, you'll need to write C++.
The problem is that you need to put your code inside a method. All you need is to move it to viewDidLoad() or any other method.
