[SOLVED] How to configure Swift framework to works in Objective-c app?

How to configure Swift framework to works in Objective-c app?

Here's my sample project: https://github.com/Tj3n/TestProject

I'm trying to create a Swift framework to use in an Objective-C app, build works fine, configuration all keep to default, added the framework in the app, imported ok, but I cannot access the class written in Swift, which already marked with @objc and public, not sure if anyone have an idea where I did wrong

Framework:

@objc(TVNFoo) @objcMembers public class Foo: NSObject {
    public static let shared = Foo()
    
    public func foo() {
        print("foo")
    }
}

App:

@import TestFramework;

[TVNFoo shared]; // Use of undeclared identifier 'TVNFoo'

Edit: By default Defines Module and Build Libraries for Distribution are set to Yes

Solution

Finally found the fix, for some reason the build setting SWIFT_INSTALL_OBJC_HEADER is responsible for copying the generated header to the built framework, but by default it's being set to No. Change to Yes and it can find the symbols now.
