Substrate

Within hours of yesterday's post, I had some new information to consider.

Let's start discussing Apple's Combine framework by discussing what's missing

Apple has released their take on RxSwift. In order to understand it, one must start from the beginning.

It’s a collection of small functions and properties without a linear story. ​ Part of me does not want to encourage people to use RxSwift for the reasons I’ve outlined. But part of me very much wants to encourage people to use RxSwift — because change comes, in part, from the community pushing the state of the art. ​ But if you do use it, and some time in the future there’s a nice, declarative way of handling events and dealing with state, then I’ll have you to thank for helping make that come true.

and spoke two words that will dramatically change my life. ​ I know that, on my death bed, I would regret not giving this a shot. I know that I would say “why did I work, rather than just trying to make it by myself”. I don’t want to make that mistake. ​ The well-traveled road brings less surprise, but is paved with the regret of poorly trodden forks not taken. ​ I would be remiss to write this post without mentioning you. It is expressly because of the people that read this website — like you — and the people that listen to my podcasts — like you — and the people that watch my videos — like you — that I’m able to make this leap. Without you giving me your attention, my family would not be afforded this amazing opportunity. ​ I can think of only a couple other pairs of words that have had similar impact on my life. Coincidentally, they were both spoken by Erin: “I do.” “I’m pregnant.”

I'm dipping my toe into screencasts. Here's my first attempt.

With about a minute to go, I opened up my AirPods, ensured they were connected to my iPhone, woke Erin up, and handed her one. She popped in the left, me the right, and we were able to share New Year’s together. We did so silently, with Declan sleeping between us, none the wiser. ​ I’ll forget AirPods one day. I won’t forget the opening of 2017. With my little family, all huddled in one hotel room bed, celebrating together, each in our own little way.

Even though it’s a steep learning curve, and it requires rewiring your brain to think about problems differently

In the fourth installment of my RxSwift primer, I'll introduce Drivers.

In the third installment of my RxSwift primer, I'm starting to show why Rx is so great.

it’s likely that the iOS team can crib their solution, platform differences aside. That’s very powerful, as it leads to us all speaking a common language, even though our actual languages are very different.

The first step to converting this to use Rx is to think of what the inputs and outputs are. What causes things to happen? What causes us to do a computation, or change what we present to the user?
