    CocoaHeadsNL Meetup, 16 March 2022

    Posted on March 17, 2022


    Live stream of our monthly CocoaHeadsNL meetup. We are back with real in-person meetup! Our last real meetup was on 19 February 2020, almost 25 months ago. This was at Triple in Alkmaar and little did we know that we had to wait so long for another meetup. Triple was one of the first companies to offer CocoaHeadsNL to host a meetup and felt more than appropriate to start again where we left off. This month we only have one talk by Jeroen Bakker. He with talk about Async Await. This programming model was introduced in Swift 5.5 and simplifies asynchronous programming. Jeroen will show you the details. The talk starts at 19:00 Hrs CET. Since it's been so long ago that we had a real in-person meetup we decided to do just one talk so that we have more time to meet up and talk again. We hope you all join us for this meetup in Alkmaar. If you can't make it you can at least join us live with this YouTube live stream.
