How to replace SFSymbol icon transparent color with white color

Question

Currently, I am using CALayer to achieve ripple effect. However, the transparent color in SFSymbol causes an issue.

I am using the following way to setup UIImageView

imageView.image = UIImage(systemName: "mic.circle.fill")
imageView.tintColor = UIColor.red

The above code yield the following outcome. (Green color is CALayer with ripple animation)

---

Instead of transparent color, I would like the mic symbol to have solid white color. I try

imageView.image = UIImage(systemName: "mic.circle.fill")?.withRenderingMode(.alwaysOriginal)

It yields

Now, I get solid white color for mic symbol. However, the circle no longer solid red color.

I further try

imageView.image = UIImage(systemName: "mic.circle.fill")?.withRenderingMode(.alwaysOriginal).withTintColor(UIColor.red)

Now, it backs to the same problem again.

Do you have any idea, how can I have a SFSymbol, with

1. Solid white for mic symbol
2. Solid red for the filled circle

Thanks.

Answer 1

I can use the following code snippet

    let image = UIImage(
        systemName: "mic.circle.fill",
        withConfiguration:UIImage.SymbolConfiguration(weight: .regular))?.applyingSymbolConfiguration(
            UIImage.SymbolConfiguration(paletteColors:[
                .white,
                .label,
                UIColor(red: 0.90, green: 0.22, blue: 0.21, alpha: 1.00)
            ])
        )
