Swift PM

[Nicola Ferruzzi]

Hello,

I've used your xcframework to make a simple swift binaryTarget pm that is "all inclusive".

https://github.com/nferruzzi/openssl

so basically all you need to use openss is

....
    dependencies: [
        .package(name: "openssl", url: "https://github.com/nferruzzi/openssl", from: "0.0.2"),
    ],
    targets: [
        .target(
            name: "MyApp",
            dependencies: [ .product(name: "OpenSSL", package: "openssl")]),
        .testTarget(
            name: "MyAppTests",
            dependencies: [.product(name: "OpenSSL", package: "openssl")]),
    ]
...

and then you can

import OpenSSL
...

        OpenSSL_SSL_init()
        ERR_load_CRYPTO_strings()

etc etc

would you be interested in adding a concept like this directly to your repo ? at the end what is really required is an URL to the latest openlssl.xcframework.zip which can be hosted by github as a release file.

There's certainly room for a PR. Is SPM ready for iOS as of yet? I haven't followed the topic in a while.

[Nicola Ferruzzi]

I think it is, I've been using it since xcode 11 on my apps without major problems, but I`ve tested this specific package with xcode 12.2 only and so far got no problems, both on mac and ios

[Davide De Rosa]

The main difference would be, however, that such a package would be binary, whereas the intent of the podspec is compiling OpenSSL locally. Is it something that can be done with SwiftPM?

[Nicola Ferruzzi]

I've not much of experience compiling C libs with SPM , but from what Ive seen compiling C files is doable but there is no room for scripts and basically no room for passing options to the compiler (just #define) without getting the package marked as unsafe (denying it the ability to be referenced by other Packages). Also, you can specify settings for specific platforms (ie macos, tvos) but not for their architecture (x86, arm).

Okay, I'll leave it up for discussion for now. I'm certainly willing to move out from CocoaPods sooner or later, so feel free to post updates on this thread.

Thank you very much!

A Swift package is now available (1.1.1l), though I'm struggling myself with a Bitcode issue.
