dyld: Library not loaded: /usr/local/opt/libressl/lib/libssl.47.dylib

Hello, I'm trying to use vapor/http, as written in the http document, I have written the following code:

import HTTP

struct EchoResponder: HTTPServerResponder {
    func respond(to request: HTTPRequest, on worker: Worker) -> EventLoopFuture<HTTPResponse> {
        let res = HTTPResponse(body: request.body)
        return worker.eventLoop.newSucceededFuture(result: res)
    }
}

let group = MultiThreadedEventLoopGroup(numberOfThreads: System.coreCount)
defer { try! group.syncShutdownGracefully() }

let server = try HTTPServer.start(hostname: "localhost", port: 8110, responder: EchoResponder(), on: group).wait()

try server.onClose.wait()

But, It crashed. The console is:

dyld: Library not loaded: /usr/local/opt/libressl/lib/libssl.47.dylib

My environment is:

• MacOS 10.15 Beta2
• Xcode 11.0 Beta2
• Swift 5.0.1

So lucky, I have solved the problem.

It seems that Xcode 11.0 has a selection in Signing & Capabilities for Disable Library Validation, make it selected and solve the problem.

Hi @RayZhao1998 where can i find Disable Library Validation? Didn't see it in app, run or Vapor tagets

Hi @hyouuu , select the Run target and in Signing & Capabilities you can add a capability called 'Hardened Runtime', then you can see the selection of Disable Library Validation.

Interesting - the whole "Hardened Runtime" section doesn't show on my vapor project. But I was able to fix it by running vapor update. Thanks anyways!
