You can use this extension to crop the longest side of your image and return a squared UIImage:

extension UIImage {
    var squared: UIImage {
        let square = size.width < size.height ? CGSize(width: size.width, height: size.width) : CGSize(width: size.height, height: size.height)
        let imageView = UIImageView(frame: CGRect(origin: CGPoint(x: 0, y: 0), size: square))
        imageView.contentMode = UIViewContentMode.ScaleAspectFill
        imageView.image = self
        UIGraphicsBeginImageContext(imageView.bounds.size)
        imageView.layer.renderInContext(UIGraphicsGetCurrentContext())
        let result = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return result
    }
    var circle: UIImage {
        let square = size.width < size.height ? CGSize(width: size.width, height: size.width) : CGSize(width: size.height, height: size.height)
        let imageView = UIImageView(frame: CGRect(origin: CGPoint(x: 0, y: 0), size: square))
        imageView.contentMode = UIViewContentMode.ScaleAspectFill
        imageView.image = self
        imageView.layer.cornerRadius = square.width/2
        imageView.layer.masksToBounds = true
        UIGraphicsBeginImageContext(imageView.bounds.size)
        imageView.layer.renderInContext(UIGraphicsGetCurrentContext())
        let result = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return result
    }
    func resizeToWidth(width:Int)-> UIImage {
        let imageView = UIImageView(frame: CGRect(origin: CGPoint(x: 0, y: 0), size: CGSize(width: CGFloat(width), height: CGFloat(ceil(CGFloat(width)/size.width * size.height)))))
        imageView.contentMode = UIViewContentMode.ScaleAspectFit
        imageView.image = self
        UIGraphicsBeginImageContext(imageView.bounds.size)
        imageView.layer.renderInContext(UIGraphicsGetCurrentContext())
        let result = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return result
    }

}
