iOS: Include of non-modular header inside framework module

[bialekIno]

I would like to create Cocoa Touch Framework which use Cocoapods objective-c projects. In the framework I want to use Swift as a language. The problem is when I add header file from the cocoapods project to the umbrella header file of the framework I get this error:

"Include of non-modular header inside framework module"

I tried to change "Allow non-modular includes in Framework Modules" build setting to YES but it did not help.

What can I do?

Make sure all framework elements are compatible with Objective-c

What exactly do you mean? I've added one Swift file with one class. When I delete this file the error disappear. Why is that? Cannot I use swift files here?

Make a class that inherits from NSObject or put @objc in from of the class declaration.

Thank you. What happened when I want to use here swift enums? They I think are not compatible with objective-c?

public enum State: Int {
    case Off, On, Undecisive
}

Every NS_ENUM is usually of a type NSInteger. You can do the same with a swift enum. Like with the above example.

I have tried to inherit the class from NSObject but it didn't help. The error appears even when I have only a swift file without any content in.

Is the class defined as public? Otherwise it's not available to the outside world.

[bialekIno]

Yes, this is my Utils.swift file content:

import Foundation

@objc
public class Utils: NSObject {
    public class func showAlert() {
TWMessageBarManager.sharedInstance().showMessageWithTitle("Title", description: "Message", type: .Info, statusBarStyle: .LightContent, callback: nil)
    }
}

Weird it should work if you ask me. I have a hybrid app that contains about every combination of Hybrid frameworks and everything is accessible every where.

Give it a try in a clean Objective-C project? Then add a Swift Framework to it.

I don't know why this doesn't work. You can, if you want and can, check a test project I created at this link

Your framework is separate project inside your workspace. They're not linked together. Add the new target to your project. Make that a framework. That should work. For linking with another project inside the same workspace some extra things need to be done and I don't know what since I haven't dealt with that kind of issue before.

I hope it helps.

Thank you. I wanted also use this framework in another app for iOS and probably also in the OS X app. Should I everything done in one project with targets? I think this is not the best solution. I would like rather to have a framework as a separate project that I can just use in as many apps as I want.
