Answer 1

These code make work

btn.mas_makeConstraints { (make:MASConstraintMaker?) in
    make?.top.equalTo()(view.mas_top)?.with().offset()(0)
    make?.left.equalTo()(view.mas_left)?.with().offset()(0)
    make?.right.equalTo()(view.mas_right)?.with().offset()(0)
    make?.bottom.equalTo()(view.mas_bottom)?.with().offset()(0)
    return()
}

Answer 2

The shortest way to do it (if you want to mirror edges of parent view is)

    self.xibView .mas_makeConstraints( { make in
        _ = make?.edges.equalTo()(self)
    })

This assignment _ = also will silence the warning about un-assignment.
