How to disable caching in Alamofire

When I send a GET request twice with Alamofire I get the same response but I'm expecting a different one. I was wondering if it was because of the cache, and if so I'd like to know how to disable it.

Answer

You have a few options.

Disabling the URLCache Completely

let manager: Manager = {
    let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    configuration.URLCache = nil
    return Manager(configuration: configuration)
}()

Configuring the Request Cache Policy

let manager: Manager = {
    let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    configuration.requestCachePolicy = .ReloadIgnoringLocalCacheData
    return Manager(configuration: configuration)
}()

Both approaches should do the trick for you. For more information, I'd suggest reading through the documentation for NSURLSessionConfiguration and NSURLCache. Another great reference is NSHipster article on NSURLCache.
