Intercept setObject functions on class properties in Swift

I have the line var user = BRUser() at the top of my Swift file class BRProfileTableViewCell.
BRUser is a struct with details such as fullName, etc. I set the user value in cellForRowAtIndexPath in my table view controller.

How could I intercept the setUser function to set the label text of the table view cell to the fullName of the user?

It sounds like you don't need to intercept anything, but rather you need to observe changes in the property, and for that, you want Swift's property observers:

var user: BRUser = BRUser() {
    willSet {
        // do something just before user is set
    }
    didSet {
        // do something just after user is set
    }
}
