How to alloc a result of function to member variable and validate in if statement in Swift

I used this syntax in objectiveC, but in Swift?

class PointClass {
    var x: Int = 0
    var y: Int = 0
    var z: Bool = false

    init(x: Int, y: Int) {
        self.x = x
        self.y = y
    }

    func getBol() -> Bool {
        return true
    }

    func toString() -> String {

        if (z = getBol()) == true {//like objc

        }

        return "x=\(x), y=\(y)"
    }
}

You can't do this in swift. You need to add separate line for this

func getBol() -> Bool {
return true

}

func toString() -> String {

  self.z = getBol()
    if self.z { // if this will true. if statement will execute

    }

return "x=\(x), y=\(y)"

}
