WKWebView does load resources from local document folder

Question

In my Swift iOS app, I want to download some dynamic HTML pages from a remote server, save them in the document directory, and display those pages from document directory.

Answer 1

The files must be in the document directory.

I implemented the following to retrieve a document:

let documentDirUrl = try! FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
let fileNameWithExtension = "IMG_0002.PNG"
let indexFileUrl = documentDirUrl.appendingPathComponent(fileNameWithExtension)
if FileManager.default.fileExists(atPath: indexFileUrl.path) {
    webView.loadFileURL(indexFileUrl, allowingReadAccessTo: documentDirUrl)
}
