iOS network debugging, like a wizard 🧙‍♂️

I have an idea to be able to capture the i/o of the networking stack and to share it automatically to some server. Or, at least, be able to share all the captured information as archive.

I have 4 schemes in my project except Release and I want to integrate in all the schemes except Release version.

Can anyone please explain the steps required to achieve my requirement?

Thanks in advance

Fixes #78

From Xcode 10.4 and Swift 5.2, there is an issue that doesn't allow Wormholy to work correctly since the initial method which uses an extension of UIApplication doesn't work anymore.

The new solution implemented is based on this. This method works like a starter engine for Wormholy. We will call appWillLaunch() method in Swift (under the StarterEngine class), when didFinishLaunchingWithOptions is fired. This is the flow:

1. App Start
2. StarterEngine receive a UIApplicationDidFinishLaunchingNotification
3. The notification fire the appWillLaunch() method under SwiftySelfAwareHelper

Testing

1. Run the demo app from Xcode 10.4 (Swift 5.2)
2. Shake the device or the simulator
3. Make sure that Wormholy appears correctly now.

@kealdishx since you worked on the initial implementation https://github.com/pmusolino/Wormholy/pull/52 of the solution based on the UIApplication extension, I'd like it if you can check if everything continues to work correctly.

Hello,

I am using wormholy in version 1.6.3 and my installation in pod file is pod 'Wormholy', :configurations => ['Debug'] for ios version 13 with swift 5.

But yet I still can't see my request body.

Please help me with the issue. And also point if I need extra configuration to set.

Thank you in advanced.

Wormholy overriding certificate pinning options while using with Alamofire. I'm using the example code block to pin certificates. While Wormholy enabled, it is not working correctly.

var serverTrustPolicies: [String: ServerTrustPolicy] = [:] 
let trustPolicy = ServerTrustPolicy.pinCertificates(
    certificates: ServerTrustPolicy.certificates(),
    validateCertificateChain: true,
    validateHost: true)

serverTrustPolicies["xxxxx.com"] = trustPolicy

let configuration = URLSessionConfiguration.default

let serverTrustPolicyManager = ServerTrustPolicyManager(policies: serverTrustPolicies)

let sessionManager = SessionManager(
    configuration: configuration,
    serverTrustPolicyManager: serverTrustPolicyManager
)

return sessionManager

Launching an app containing Wormholy results in an immediate abort with this message:

| Swift class extensions and categories on Swift classes are not allowed to have +load methods

When using Wormholy, a UIWebView that receives a 302 Redirect response issues 2 requests for the redirect URL. You can see it happening by monitoring the web requests in Charles. This does not happen with WKWebView but there is a bug with that implementation which means I have to use UIWebView for now.

I've attached a sample project which demonstrates the failing behaviour, and also screenshots illustrating the duplicate request.

Hi!

Great idea!

If I use the flag "use_modular_headers!" in my pod file I get the following error: /Pods/Wormholy/Sources/Objc/Wormholy+Foo.m:9:9: 'Wormholy/Wormholy-Swift.h' file not found

I use the latest build for cocoapods directly from the repository. Wormholy is the only pod that gives me grief.

I was trying to build with Wormholy, in iOS 12 with Xcode 10, as a pod, when I was getting a lot of errors having to do with changes to Swift.

So I forked it really quick and ran the automatic converter with Swift.

I was having issue trying to export this as a framework and manually adding it to my project to test the changes.

Summary

On darkmode enabled, when searching a keyword inside Request Body or Response Body, the screen shows matched (highlighted) text only. The remaining text appear black, blend with its background color, so it can't be read. The issue was raised on https://github.com/pmusolino/Wormholy/issues/128

Steps to reproduce

• Run in darkmode
• Shake to trigger Wormholy interface
• Tap one of API listed there
• Tap View Body inside Request Body or Response Body section
• Tap search button, search any keyword contained in request/response body

What is the current bug behavior?

The screen shows highlighted matched text only. The remaining are black, blends with its background color.

What is the expected correct behavior?

The screen should show remaining non-matched text also.

Root Cause

On WHTextView inside highlight(text:with:font:highlightedFont:) -> [NSTextCheckingResult] method, it adds attributes only to the highlighted text. But for the default text (non-matched) attribute wasn't set yet. That's why its text color was black as same as its background color.

How to solve ?

Set attributes .foregroundColor to UIColor.label as default attribute to the text. Please note that UIColor.label is only available for iOS 13 or above, since dark mode feature was first introduced in that iOS version.

Relevant logs and/or screenshots

| Before | After | | ------ | ------ | | | |

Description : When doing search in Response/Request Body, the text is not visible because text color blend with background color.

Step to reproduce :

1. Make sure you're running in Darkmode.
2. Shake Apps to trigger wormholy screen.
3. Tap one of API listed there.
4. Tap Request Body or Response Body.
5. Search a keyword on search bar.
6. Your Screen only show matched keyword, other text is not visible (see screenshoot below)

Hey, Recently i used 2 tools for network debugging, Wormholy and Proxyman. And i was wondering what if we can do a mapping and replace the response body on Wormholy like Proxyman as well. If it's possible, what's the concept to be able achieve that?

Many thanks!

I was wondering if Wormholy records all app traffic, is it possible to get data size statistics like how many bytes sent received (zipped and unzipped) and timing per each request? Thanks!
