Erase all cookies in NSURLSession iOS

Question

How can I erase all cookies from the NSHTTPCookieStorage.sharedHTTPCookieStorage? The only methods I am aware of delete a single specified cookie, however, the cookies are handled behind the scenes by NSURLSession. (Programming in Swift)

This achieves the same result as the other answers but with one line of code:

HTTPCookieStorage.shared.cookies?.forEach(HTTPCookieStorage.shared.deleteCookie)

Why this code is not generating crash for modifying collection while iterating it? Just want a confirmation on it. – Fauad Anwar May 29 '19 at 14:55

@FauadAnwar Arrays in Swift are structs and thus value types, so they get copied rather than referenced. – Andrew Johnson Sep 02 '21 at 16:23

Similarly, for swift 3.0+, xCode 8.0+

let cookieStore = HTTPCookieStorage.shared
for cookie in cookieStore.cookies ?? [] {
    cookieStore.deleteCookie(cookie)
}
