Swift 4.2

I really liked @Luca Angeletti solution. I hade the same question as @jonauz about transparent background. So with this small modification you get the same thing but with clear background color.

I didn't have the rep to answer in a comment.

import UIKit

extension String {
    func emojiToImage() -> UIImage? {
        let size = CGSize(width: 30, height: 35)
        UIGraphicsBeginImageContextWithOptions(size, false, 0)
        UIColor.clear.set()
        let rect = CGRect(origin: CGPoint(), size: size)
        UIRectFill(CGRect(origin: CGPoint(), size: size))
        (self as NSString).draw(in: rect, withAttributes: [NSAttributedString.Key.font: UIFont.systemFont(ofSize: 30)])
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image
    }
}
