Originally assigned to: @NghiaTranUIT on GitHub.

Hello,
first of all, thanks to proxyman, it's super easy to debug network traffic.

I'm trying to integrate Atlantis in my objective-C AppDelegate.m. but the Xcode build fails with the error 'Atlantis-Swift.h' file not found.

I followed the README.md documentation and added #import "Atlantis-Swift.h".
I'm using the Atlantis version 1.7.1 (installed using cocoapods)

Thanks in advance.

Hey @apostopher

I've just created a new Objective-C Project and integrate Atlantis by Cocoapod. I didn't get any problem.

#import "AppDelegate.h"
#import "Atlantis-Swift.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    [Atlantis startWithHostName:nil];
    return YES;
}

Can you download and run this objc example: https://www.dropbox.com/s/k9cbdqhmyil5lo6/Objective-C-Example.zip?dl=0

I'm not sure if Atlantis could work with React-Native if the Network library in your project doesn't use URLSession to make a Request.

Do you know a React-native example that I can test out? 🤔

I think react-native's fetch API internally uses NSURLSession. I'll try a sample app tomorrow. I'll share my findings with you.

@NghiaTranUIT i investigated the issue and here are my 2 cents:
This error happens if the Podfile does not have use_frameworks! line.

Unfortunately in my case if i add use_frameworks! my other deps fail to build. :-(

Solution

🎉 I found a working solution using a plugin called cocoapods-user-defined-build-types

1. Install the gem: $ gem install cocoapods-user-defined-build-types
2. Add these above your target in Podfile

plugin 'cocoapods-user-defined-build-types'
enable_user_defined_build_types!

3. Add atlantis pod:

pod 'atlantis-proxyman', :build_type => :dynamic_framework

This fixed my issue and Atlantis works perfectly.

Original Comment

I'm running into this exact issue.
I've confirmed the pod was installed, it shows up in Podfile.lock. atlantis-proxyman (1.12.0)
Tried cleaning before building and it did not help.

React Native project - Running on M1 (arm64)
Xcode 13.1 (13A1030d)
MacOS 12.0.1

Unfortunately, I don't have any plan to bring Atlantis to Android because I have no experience on Android and Atlantis is heavily depends on Method Swizzling and URLSession, which are not available on Android world.

It's a known issue because React Native doesn't use native URLWebsocketSession to make a WS/WSS. They use their own WS socket. Thus, Atlantis doesn't work.

I use react-native trying to build ios.

I tried the workaround suggested by @archcorsair and after many additional steps to be able to install the plugin (install rbenv, update ruby, update this update that, etc.) I finally hit this error on pod install so gave up on atlantis.

Flipper or proxyman(+helper) seem to work for my needs.

Changing the use_frameworks! setting will break the build somewhere else.
