Hey guys, is there anything I can do to help get this PR merged? Quite eager to implement certificate pinning in my iOS app.

@magneticrob thanks for chiming in, really the main block right now is a review from a maintainer. I can't do that at the moment.

If you could review this yourself and/or test it out in your own app that would be helpful but I can't say it will be merged immediately after that.

In the meantime though, you could use @gytiskv's fork in your app.

Thanks for submitting this.

Is there any way we can get your changes against current master? There's some odd stuff going on with version numbers, and I'm not sure why; I suspect it's to do with the basing of your branch. Certainly, we don't want to be downgrading Swift version and a bunch of dependencies.

There don't appear to be automated tests for the new functionality. We’ll need those.

I haven't opened the project in Xcode, but looking at the changes there appears to be a new tester app? What’s going on there?

Closing as it seems stale and requires an extensive rebase on the master branch.
