Clear WKWebView's cookies and website data storage, very useful during development.

WebCacheCleaner.swift

import Foundation
import WebKit

final class WebCacheCleaner {
    
    class func clean() {
        HTTPCookieStorage.shared.removeCookies(since: Date.distantPast)
        print("[WebCacheCleaner] All cookies deleted")
        
        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")
            }
        }
    }
    
}

Here's the different types of code using async/await

(Without the foreach. This works for me.)

let dataRecords = await WKWebsiteDataStore.default().dataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes())
        
await WKWebsiteDataStore.default().removeData(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(), for: dataRecords)

(With the foreach. Requires CollectionConcurrencyKit)

let dataRecords = await WKWebsiteDataStore.default().dataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes())

await dataRecords.asyncForEach { record in
    await WKWebsiteDataStore.default().removeData(ofTypes: record.dataTypes, for: [record])
}

Thank you very much

Thanks man!

Team,
Where we find all WebKit data in our IOS App storage ?
