Hi @knowOnline thanks for your question. There is a possibility. You just need to check for the targetFrame of the navigationAction before you call UIApplication.shared.open(url).

if navigationAction.targetFrame == nil {
	UIApplication.shared.open(url)
	decisionHandler(.cancel)
} else {
	decisionHandler(.allow)
}

Im getting error with this when pressing a link.

Completion handler passed to -[test.pr webView:decidePolicyForNavigationAction:decisionHandler:] was called more than once

@Miztra cup that is fixed now. I removed the changes that were causing the error to appear.

Hi, how do I check for URLs and application magnet links? My web application needs to launch another application via magnet links but the following code will handle links other than the default webview URL to open in browser or either just ignore. Thanks.

@raymond-1227 if you want want to detect magnet-links you can use a similar approach as how this code detects the links. You can use the scheme attribute of the URLComponent.

if components?.scheme == "magnet" {
    // Do whatever you want.
}

I tried the method, but I'm not sure why if I use the code, it'll say WebPageProxy::didFailProvisionalLoadForFrame: frameID=575, domain=NSURLErrorDomain, code=-999 when the code was set like this:

if components?.scheme == "roblox-player" {
      decisionHandler(.allow)
}

I think the error was dedicated to the custom scheme, because if I use webview.uiDelegate (which doesn't handle external links) the error doesn't appear.
