    Bagel

    Bagel

    A little native network debugging tool for iOS

    Bagel is a little native iOS network debugger. It's not a proxy debugger so you don't have to mess around with certificates, proxy settings etc. As long as your iOS devices and your Mac are in the same network, you can view the network traffic of your apps separated by the devices or simulators. Most basic usage is to start Bagel iOS before any network operation. Since Bagel exposes every request info to the public it would be better if you disable it for the store versions. By default, Bagel gets your project name and device information. The desktop client uses this information to separate projects and devices. You can configure these if you wish. Bagel framework communicates with the desktop client by using Bonjour protocol. You can also configure these Netservice parameters.
