Answer 1

Quick solution for SWIFT 4.2

    let fontName =  "PFHandbookPro-Regular"
    let fontSize = 20
    let fontSetting = "<span style=\"font-family: \(fontName);font-size: \(fontSize)\"</span>"
    webView.loadHTMLString( fontSetting + myHTMLString, baseURL: nil)

span is an inline element, meaning that it can be on a line with other elements

Answer 2

Just prefix a <font face> tag to your string before loading into the webView.

NSString *body = [plist objectForKey:@"foo"];
NSString *htmlString = 
    [NSString stringWithFormat:@"<font face='GothamRounded-Bold' size='3'>%@", body];
[webView loadHTMLString:htmlString baseURL:nil];

func webViewDidFinishLoad(_ webView: UIWebView) {
    webView.stringByEvaluatingJavaScript(from: "document.getElementsByTagName('body')[0].style.fontFamily =\"-apple-system\"")
}

I have just put the default iOS font for this example
