无法在Swift 3中使用没有baseUrl的WKWebView中加载数据？

Question

I'm trying to load some Data in a WKWebView and the compiler won't let me pass in nil nor URL() for the baseUrl parameter. Is there a workaround? I don't care at all about a baseUrl.

Below is my code with trying nil and then trying URL() along with the errors, respectively.

self.webView.load(data!, mimeType: "image/png", characterEncodingName: "UTF-8", baseURL: nil);

error: nil is not compatible with expected argument type 'URL'

self.webView.load(data!, mimeType: "image/png", characterEncodingName: "UTF-8", baseURL: URL());

error: cannot invoke initializer for type 'URL' with no arguments

Answer 1

I believe you will always need a baseURL.

Just invoke it with URL(string: "http://localhost")

Browsers always load from a URL and WKWebView behaves like a browser so it requires some sort of base URL.
