Unable to use MongoKitten in MacOS app - missing required module 'CNIOOpenSSL

[Ramya Rao]

Describe the bug
I am trying to connect to MongoDB using MongoKitten driver in my MacOS app. I used the swift package manager to install the MongoKitten driver, however I keep getting an error

To Reproduce
My Package.Swift is as follows

import PackageDescription

let package = Package(
    name: "Dependencies",
    products: [
        // Products define the executables and libraries produced by a package, and make them visible to other packages.
        .library(
            name: "Dependencies",
//            type: .static,
            targets: ["Dependencies"]),
    ],
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        // .package(url: /* package url */, from: "1.0.0"),
        .package(url: "https://github.com/OpenKitten/MongoKitten.git", from: "5.0.0"),
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages which this package depends on.
        .target(
            name: "Dependencies",
            dependencies: ["MongoKitten"]),
        .testTarget(
            name: "DependenciesTests",
            dependencies: ["Dependencies"]),
    ]
)

Expected behavior
Ability to import MongoKitten and connect to the database in macOS app

Server-side Swift:

• OS: macOS 10.14 Mojave
• Swift Version: 5
• MongoKitten Version : 5.0.0

However, when I tried to build and run the code with "import MongoKitten"

I get the following error
missing required module 'CNIOOpenSSL'

I request you to let me know how to resolve this issue. I can provide any other information to help solve the matter

That version of SwiftNIO requires you to install openSSL/libreSSL headers via homebrew I believe.

[Ramya Rao]

I did try brew install libreSSL, but to no avail.

[Joannis Orlandos]

@ramyrao you've also selected your own machine as the target in Xcode, right?

[Ramya Rao]

Yes, that correct

[Robbert Brandsma]

@ramyrao Would it be possible to test if it works for you with the Swift Package Manager support in the current Xcode beta?

[Joannis Orlandos]

I just found this snippet, hope it helps you!

export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"
