P2: Important Description
While attempting to build binaries for macOS 10.12 and 10.13 using homebrew in this pull request, a compiler warning was discovered in qwebview_darwin.mm that caused the build to fail because `-Werror` was supplied for that specific error:
21:13:21 qwebview_darwin.mm:261:24: error: 'loadFileURL:allowingReadAccessToURL:' is only available on macOS 10.11 or newer [-Werror,-Wunguarded-availability] 21:13:21 [wkWebView loadFileURL:url.toNSURL() 21:13:21 ^~~~~~~~~~~~~~~~~~~~~~~~~ 21:13:21 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/System/Library/Frameworks/WebKit.framework/Headers/WKWebView.h:102:1: note: 'loadFileURL:allowingReadAccessToURL:' has been explicitly marked partial here 21:13:21 - (nullable WKNavigation *)loadFileURL:(NSURL *)URL allowingReadAccessToURL:(NSURL *)readAccessURL API_AVAILABLE(macosx(10.11), ios(9.0)); 21:13:21 ^ 21:13:21 qwebview_darwin.mm:261:24: note: enclose 'loadFileURL:allowingReadAccessToURL:' in an @available check to silence this warning 21:13:21 [wkWebView loadFileURL:url.toNSURL() 21:13:21 ^~~~~~~~~~~~~~~~~~~~~~~~~ 21:13:21 1 error generated.
