WKWebView Cached Old S3 Bucket

I have an iOS app that gets a PDF from an S3 bucket and displayed the PDF using WKWebView.

I have changed/updated the PDF when accessing the S3 link I see the new PDF when using Android I see the new PDF

however iOS still shows the old PDF? Any Ideas?

Is there a way to clear WebView Cache? I have tried Settings clearing Safari cache I have tried setting no-cache to the S3 bucket PDF

viewController.html = "https://xxxx.s3.amazonaws.com/voucher/NEW.pdf"
let htmlData = "<!DOCTYPE html><html><header><meta name='viewport'></header><body><object width=\"100%%\" height=\"100%%\" align='center' data='\(html)'></object></body></html>"
webview.loadHTMLString(htmlData, baseURL: nil)

Thanks in advance

Solution

  • try to clean local web data:

    WKWebsiteDataStore.default().fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
        records.forEach { record in
            WKWebsiteDataStore.default().removeData(ofTypes: record.dataTypes, for: [record], completionHandler: {})
            print("[WebCacheCleaner] Record \(record) deleted")
        }
    }
