Argument labels do not match any available overloads error when updating to Swift 3

When converting Swift syntax to the latest version I am getting the error:

Argument labels '(_:, fromDate:)' do not match any available overloads

At the following line:

let components = calendar.components(componentOptions, fromDate: NSDate())

For reference, here is the line in context of other constants/variables.

let calendar = NSCalendar.current
        let componentOptions:NSCalendar.Unit = .weekday
        let components = calendar.components(componentOptions, fromDate: NSDate())
        var weekday = components.weekday

        let days = ["S", "S", "M", "T", "W", "T", "F"]

What exactly is my error and how can I solve it? Seems like a simple fix, I just can't figure out.

Thanks.

UPDATE:

In the line: 

let components = calendar.components(componentOptions, fromDate: NSDate())

I changed fromDate to from and after a series of Xcode recommended changes I got:

let components = calendar.dateComponents(componentOptions, from: NSDate() as Date)

but am now getting the error: 

Cannot convert value of type 'NSCalendar.Unit' to expected argument type 'Set<Calendar.Component>'

Try these lines:

let calendar = Calendar.current
let components = calendar.dateComponents([.weekday], from: Date())
