Importing Swift Package in Objective-C Application

If I compile this source code in Swift Package, and try to import it in Objective-C based App or Package, the code refuses to compile.

Code Block swift
import Foundation
import simd
@objc public class TestPoint: NSObject {
    @objc public var p: vector_float3 = []
}

It gives following error:
"unknown type name 'vector_float3'"

The problem is that Objective-C Generated Interface Header "<Package>-Swift.h" does not import simd framework. I tried to make "umbrella header":

Code Block objective-c
#import <Foundation/Foundation.h>
@import simd;
FOUNDATION_EXPORT double TestPackageVersionNumber;
...

But with no success. This approach works when making a swift framework, unfortunately not for packages.
I tried to move h file into include directory, to define public header path... with no success. Is this possible somehow?
