Getting this error in Swift 2.0.

Binary operator '|' cannot be applied to two UIViewAutoresizing operands

Here is the code:

let view = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 568))
addSubview(view)
view.autoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight

Any idea what can be the problem? enter image description here

Effectively the same problem as in Swift 2.0 - Binary Operator “|” cannot be applied to two UIUserNotificationType operands. – Martin R

The OptionSetType got an updated syntax for Swift 2.x and another update for Swift 3.x

Swift 3.x

view.autoresizingMask = [.flexibleWidth, .flexibleHeight]

Swift 2.x

view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]

This are the differences between Swift 1.2 and 2:

// swift 1.2
view.autoresizingMask = .FlexibleWidth | .FlexibleTopMargin

// swift 2
view.autoresizingMask = [.FlexibleWidth, .FlexibleTopMargin]
