check you mask image background is transparent or not ? set your mask imageview to UIColor.clear and setyour main image view to yellow color @KhushbuDesai — Divyesh Gondaliya, Aug 21 '17 at 11:49
if this not will be work then tray to this img.mask?.backgroundColor = UIColor.yellow img.mask?.tintColor = UIColor.yellow @KhushbuDesai — Divyesh Gondaliya, Aug 21 '17 at 11:51

let templateImage = originalImage.imageWithRenderingMode(UIImageRenderingModeAlwaysTemplate)
myImageView.image = templateImage
myImageView.tintColor = UIColor.orangeColor()

Heres a small code snippet with background color change

import Foundation
import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var trial: UIImageView!
    override func viewDidLoad() {
        super.viewDidLoad()
        let mask = UIImage(named: "mask_image")
        let image = UIImage(named: "wallpaper")

        trial.image = self.maskImage(image: image!, withMask: mask!)
        trial.backgroundColor = UIColor.red
    }
    func maskImage(image: UIImage, withMask maskImage: UIImage) -> UIImage {
        let maskRef = maskImage.cgImage
        let mask = CGImage(
            maskWidth: maskRef!.width,
            height: maskRef!.height,
            bitsPerComponent: maskRef!.bitsPerComponent,
            bitsPerPixel: maskRef!.bitsPerPixel,
            bytesPerRow: maskRef!.bytesPerRow,
            provider: maskRef!.dataProvider!,
            decode: nil,
            shouldInterpolate: false)
        let masked = image.cgImage!.masking(mask!)
        let maskedImage = UIImage(cgImage: masked!)
        // No need to release. Core Foundation objects are automatically memory managed
        return maskedImage
    }      
}
