Reproduce on iOS 12.2 device:

1.Create a wkwebView like :
WKWebView *webView = [[WKWebView alloc] initWithFrame:CGRectMake(0, 0, size.width, (size.height - 100)/2) configuration:[WKWebViewConfiguration new]];

2.Load online page like :
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.baidu.com"]]];

3.After webView finish load, load a local file like:
NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject] stringByAppendingPathComponent:@"test.html"];
[webView loadFileURL:fileURL allowingReadAccessToURL:fileURL];

Then you can see error like:
