The most common issue requests don't get logged is the use of a custom NSURLSession (search for "NSURLSession" or "NSURLSessionConfiguration" in your code or in the 3rd party library's code). In this case you must add the following in the default configuration

Swift

let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
configuration.protocolClasses?.insert(NFXProtocol.self, atIndex: 0)

Obj-C

NSURLSessionConfiguration* config = NSURLSessionConfiguration.defaultSessionConfiguration;
config.protocolClasses = @[[NFXProtocol class]];

Below you can find some library-specific workarounds

Alamofire

Due to the way Alamofire uses NSURLSession, you’ll need to do a little more than the standard installation to monitor all requests. The simplest way to do this is to create a subclass of Manager to handle your requests as this

import Alamofire

class NFXManager: Alamofire.Manager
{
    static let sharedManager: NFXManager = {
        let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
        configuration.protocolClasses?.insert(NFXProtocol.self, atIndex: 0)
        configuration.HTTPAdditionalHeaders = Manager.defaultHTTPHeaders
        let manager = NFXManager(configuration: configuration)
        return manager
    }()
}

Then just use NFXManager.sharedManager instead of Alamofire.request()

KFSwiftImageLoader

Same here. Please replace

internal lazy var session: NSURLSession = {
    let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    configuration.requestCachePolicy = .ReturnCacheDataElseLoad
    configuration.URLCache = .sharedURLCache()
    return NSURLSession(configuration: configuration)
}()

with

internal lazy var session: NSURLSession = {
    let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    configuration.protocolClasses?.insert(NFXProtocol.self, atIndex: 0) //added line
    configuration.requestCachePolicy = .ReturnCacheDataElseLoad
    configuration.URLCache = .sharedURLCache()
    return NSURLSession(configuration: configuration)
}()

in the KFImageCacheManager.swift file

Note: You will get image log only the first time because KFSwiftImageLoader caches the images and doesn't request them again

More #21

No HTTP body for requests

Unfortunately, due to a limitation in NSURLProtocol, netfox is unable to log the HTTP body of some requests (check this radar for more details)

jasoncabot posted a nice workaround on this:

You can do the following to monitor these requests

if let bodyData = mutableURLRequest.HTTPBody {
    NSURLProtocol.setProperty(bodyData, forKey: "NFXBodyData", inRequest: mutableURLRequest)
}

Tip for Alamofire users: Subclass URLRequestConvertible and make all the work there
