bitrise ( https://www.bitrise.io ) is the best that I've used so far for building iOS apps. Its elite package is also really fast if you can afford it. I've used travis (slow, 45 m…

You could try Flow ( https://flow.org ) as you're already familiar with JavaScript. I've been using it after primarily using static languages and it's been great so far.

How are blocks not required to be cryptographically verifiable?

Sorry, I wasn't clear, I meant trust-less consensus (proof of work). Distributed transactions in an RDBMS requires trusting all the hosts it runs on.

No because it's cheap to produce hashes for git.

Postgres doesn't do distributed consensus though does it.

Yes it's more cognitive overhead but it's a more functional than imperative style which usually has many advantages. If the functions are named well (naming being the hardest probl…

I agree that you can split validation parts into separate functions but this is conflating two concerns, for example the rewriting of the guard statement from guard item.count > 0 …

extensions let you do this with enums (as well as protocols): enum Car { case Red case Blue } extension Car { func hello() { print("hello") } } let x = Car.Blue x.hello() https://d…

And with associated values in enum types they behave in a similar way to case classes in Scala that extend a sealed trait. For example I've been working on a Json library that stor…

Yeah you're right. If you want to stick with value types and store those values in an Array where the array can only store one type then you have to use an Enum instead of classes.…

Apparently un-pairing and pairing again fixes the issue, so will give this a try.

I'm also having battery issues since the GM release. Beta 5 was fine, but now it doesn't even get through the morning.

Also why no mention for the enum, the other value type that allows for pattern matching?

What a stupid, long blog post

I also ran into this problem a couple of times.. It's not the only issue. I put it down to how new the language is and how many non-critical issues they can fix. Swift 1.2 has been…
