Open Source Swift Debuggers

Netfox provides a quick look on all executed network requests performed by your iOS or OSX app. It grabs all requests - of course yours, requests from 3rd party libraries (such as AFNetworking, Alamofire or else), UIWebViews, and more.

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.

InAppViewDebugger is a library that implements a view debugger with a 3D snapshot view and a hierarchy view, similar to Reveal and Xcode's own view debugger. The key distinction is, as the project title suggests, that this can be embedded inside the app and used on-device to debug UI issues without needing to be tethered to a computer. 3D snapshot view implemented in SceneKit: Gesture controls for zooming, panning, and rotating. Hierarchy (tree) view that synchronizes its selection with the 3D view: This is a feature I really wanted in Xcode, to be able to visually find a view and see where it is in the hierarchy view. Support for iPad and iPhone: Layouts are designed specifically for each form factor. Extensible: The base implementation supports UIView hierarchies, but this is easily extensible to support any kind of UI framework (e.g. CoreAnimation or SpriteKit)

Start debugging iOS network calls like a wizard, without extra code! Wormholy makes debugging quick and reliable. Add it to your project, and that's all! Shake your device or your simulator and Wormholy will appear! You don't need to import the library into your code, it works magically! To integrate Wormholy into your Xcode project using Carthage, specify it in your Cartfile. Record all app traffic that uses NSURLSession. Reveal the content of all requests, responses, and headers simply by shaking your phone! No headaches with SSL certificates on HTTPS calls. Find, isolate and fix bugs quickly. Swift & Objective-C compatibility. Also works with external libraries like Alamofire & AFNetworking. Ability to blacklist hosts from being recorded using the array ignoredHosts. Ability to export API requests as Postman collection.
