Here's my sample project:

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]; // Error undeclared identifier
