Hello,

i am searching a way to decode a Base64 decoded SVG Image and display it with the swift Image component.

I always get nil when trying to convert my decoded data to an Image.

func convertBase64StringToImage (imageBase64String: String) -> UIImage {
    print("imageBase64String: ", imageBase64String)
    var rawbase64String = imageBase64String

    if imageBase64String.contains("data:image/svg+xml;base64,") {
        print("incoming avatar is SVG")
        rawbase64String = imageBase64String.replacingOccurrences(of: "data:image/svg+xml;base64,", with: "")
    }
    else {
        print("incoming avatar has unknown file type")
        rawbase64String = defaultAvatar()
    }

    print ("Using avatar: ", rawbase64String)
    let dataDecoded = Data(base64Encoded: rawbase64String)
    let decodedImage = UIImage(data: dataDecoded!)
    print ("decodedImage: ", decodedImage)
    return decodedImage!
}

decodedImage gets always nil

Any ideas?

You cannot initialize a UIImage from an SVG like that. The only way to use an SVG with UIImage is if the SVG is already in your assets catalog.

Really sad...

So there is no way to display SVG which i receive in base64 string ? Or is it maybe possible to save base64 SVG string in assets programatically and the use it?

Not natively in a UIImage. You can use a third party package, like SVGKit, or you could try displaying your SVG in a WKWebView.
