I\'m getting an image\'s Size and used the below code. It was working perfectly fine with Xcode 6.0.1. After updating to Xcode 6.1, I\

Answer 1

In addition to @Antonio's answer you can use nil coalescing operator(??) to get a default size in case image initializer is failed. Here is how:

let size = image?.size ?? CGSizeZero

Answer 2

That initializer is now a failable initializer, and as such it returns an optional UIImage.

To quickly fix your bug just unwrap the image:

let sizeOfImage = image?.size

but I presume you will reference the image variable more than just once in your code, in that case I suggest using optional binding:

if let image = image {
    let sizeOfImage = image.size
    /// ...
    /// Use the image
}

Answer 3

Once you’re sure that the optional does contain a value, you can access its underlying value by adding an exclamation mark (!) to the end of the optional’s name. In your case: image.size!

Answer 4

you can use like this:

    let image = UIImage(named: "photo1.png")
    let sizeOfImage = image?.size

    imageView.image = image
    imageView.frame = CGRect(origin: CGPoint(x: 0, y: 0), size: sizeOfImage!)
