NSLayoutFormatOptions - allZeros and

On Xcode7 beta, I am facing the following issues:

I am trying to create 2 constraints using visual format:

Constraint 1:

        let views1 = ["v1" : v1]

        let verticalConstraints1 = NSLayoutConstraint.constraintsWithVisualFormat("V:|-[v1]",
            options: .allZeros,
            metrics: nil,
            views: views1)

I get an error for .allZeros, What is the way to resolve this ?

Constraint 2:

        let views2 = ["v2" : v2]

        let verticalConstraints2 = NSLayoutConstraint.constraintsWithVisualFormat("V:|-[v2]",
            options: .AlignAllLeft | .AlignAllRight,
            metrics: nil,
            views: views2)

I get an error for .AlignAllLeft | .AlignAllRight, What is the way to resolve this ?
