converting setter, getter variable from objective C to swift 2.2 - objective-c

Question

I am facing issues while converting from Objective C to Swift 2.2.. Can anyone help me..??
Here is the code in Objective C
variables declared as
#property (nonatomic, assign) NSInteger currentViewControllerIndex;
#property (nonatomic, getter = isWrapEnabled) BOOL wrapEnabled;
and the variable setting functions in Objective C are
- (void)setWrapEnabled:(BOOL)sWrapEnabled {
wrapEnabled = sWrapEnabled;
[self.view layoutIfNeeded];
}
- (void)setCurrentViewControllerIndex:(NSInteger)curViewControllerIndex {
[self scrollToViewControllerAtIndex:curViewControllerIndex animated:NO];
}
This is how i have written in Swift
var tmpWrapEnabled : Bool = Bool()
internal(set) var wrapEnabled : Bool? {
get {
return tmpWrapEnabled
}
set(newValue) {
if newValue == true {
tmpWrapEnabled = newValue!
self.view.layoutIfNeeded()
}
}
}
var tmpCurrentViewControllerIndex : NSInteger = 0
internal(set) var currentViewControllerIndex : NSInteger? {
get {
return tmpCurrentViewControllerIndex
}
set(newValue) {
tmpCurrentViewControllerIndex = newValue!
}
}

Basically you need only the didSet observers, for the rest the variable behaves as a normal variable.
var wrapEnabled : Bool {
didSet {
if wrapEnabled {
self.view.layoutIfNeeded()
}
}
}
var currentViewControllerIndex : Int {
didSet {
scrollToViewControllerAtIndex(currentViewControllerIndex, animated:false)
}
}
Consider that the observers are not called when the initial value is assigned to the variable.
