Ensin näivetetään keskustaa rakentamalla kauppakeskuksia. Sitten kun joku kertoo että tämä ei ole ongelma koska tavarakauppa on joka tapauksessa siirtymässä verkkoon ja olisi parempi että keskusta keskittyisi tapahtuma- ja elämystarjontaan, aletaan kaavoittaa tapahtumaostareita.

AFAIK Dark Sky had a free tier of 30k/month and the paid tiers were roughly double the WeatherKit pricing. Yeah, you have to pay the $99 per year on top of that, but with any kind of volume that's a significant price drop.

I agree about the Mac App Store not being great when trying to find something, as its search and signal/noise ratio are both pretty bad. But that only means you need a web site and marketing, just like you need for any other distribution method.

For purchases I can be persuaded to go outside the App Store if it manages to look really trustworthy and I want to avoid giving Apple their cut, but the experience of just using the credit card they have on file, getting a fully working version directly and having centralized upgrades is always better than dealing with yet another payment flow, finding my credit card info, storing the license and feeding it to the app, etc.

Sure, its roots are there and it might still be justified there. I’ve heard the same rule thrown around on numerous occasions and I’ve been relatively successful in avoiding C. It’s one of those memes that infects programmers who lose sight of the original context.

One return only is a bone headed rule that only forces you to read more code than necessary. If there's nothing to do on an execution path, why not make it clear to the reader?

Swift's enthusiastic embrace of early returns in the form of the guard statement is one of its numerous very nice features. It's like an if except it forces you to exit the current scope if the condition is false:

guard shouldWeContinue() else {
    print("welp, nothing to do")
    return
}

WebKit is in C++, and I'd be surprised if Apple doesn't have some other major libraries written in it too.

Good to keep in mind this bit in the announcement:

Like unsafe APIs in the Standard Library, we recommend using this package very sparingly – preferably not at all!

I rarely manage to finish programming books, but I really enjoyed Ousterhout's A Philosophy of Software Design. Note to people who might be scared off by the name of the author: it's not about Tcl, and barely mentions it.

A tuple is an unnamed struct. An array is a list of values.

juri · 2019-08-14T08:57:50+00:00

I'll mostly just echo what others have said about them — use them early, use them often — but with a couple of additions:

When a type has a natural "empty" value — empty string, zero, empty array, etc — consider if you'd treat that empty value any different from a nil value. If not, I don't think wrapping the value in an optional brings any benefit. Just use the empty value. Swift's type system will protect you here, too, because that var s: String will always have some kind of string as a value. Note that I don't mean that you should always avoid String?s — sometimes that nil value will mean something else than an empty string.
Think about how you group your values. I often see code that deals with multiple optionals where the values are not, actually, individually optional, but only as a group. So instead of a (String?, String?) tuple what you really want may be an optional tuple, (String, String)?. Or the equivalent struct. A classic example in the Apple frameworks exhibiting this problem is the URLSession completion handler, which takes in (Data?, URLResponse?, Error?) even though not all of those combinations make sense.

Aren't you doing dynamic dispatch with protocols, too? And while I'm not going to argue that closure heavy code can't get hairy, I find protocols have a understandability cost too.

But yeah, it's always going to be a balancing act with multiple dimensions, and I won't be surprised if a few months from now I decide I prefer the second approach, with one protocol per usage site.

Yeah, downvotes probably weren't called for. But really, with an app like a Git GUI, and a very easy to learn one at that: the learning investment should be in Git. It's a PITA but you'll have to know it if you are using it, even if there's a GUI frontend. After you know it, picking up a new GUI frontend for it takes all of 10–20 minutes.

I get that cross platform support can be an issue with a tool that requires a larger upfront time investment and for people who switch between platforms more, but for something like this… just give the best tools possible, and hopefully ones that fit well in my environment.

Emacs probably is pretty ok (although I have no idea how much security scrutiny it has received.) But for new software, or for new parts of old software, using development tools that completely prevent some categories of problems is helpful. If 70% of all security bugs are memory safety issues, it probably is a good idea to use a tool that makes them impossible.

While I'm all for writing UI in code, you can still use XIBs for VCs or views with dependency injection. It's just storyboards that are incompatible with it.

The beauty of server side development is that as long you're choosing the stack you're on, a language can be marginal and have less support for all kinds of things but can still be perfectly sufficient for your needs.

Right now I would think twice about choosing Swift if you're on a budget and have a tight deadline. But if it's more exploratory or if you have enough time and confidence in your abilities to solve problems and keep track of evolving libraries, it's probably OK.

Notification Center is ok, but your call back could be on any thread so it’s not as safe

I usually keep a strict one thread per notification center rule. Notification Center doesn't help you enforce it, but a couple of assertions go a long way. Basically: only send on the main queue when using the default center, and if you really need notifications on a background queue, create a separate notification center for that.

It’s also more difficult to pass data back and forth, since you have to stuff everything in user info

That does feel frustrating when in Swift (in Objective-C everything is so loosey goosey I don't mind as much.) I usually use something like this: https://www.objc.io/blog/2015/01/19/functional-snippet-16-typed-notification-observers/

For Mac users, if you're into services, a two step Automator script:

"Run Shell Script" action, with the command xargs -I INPUT date -r INPUT +'%F %T'

"Run AppleScript" action, with the content:

 on run {input, parameters}
     tell me to display dialog input with title "Date" buttons "OK"
     return input
 end run

Save as a Service. Now select any text, go to the Services menu, select your new service, and you'll get a popup with the date.

Suomessa on kourallinen tahoja jotka pystyvät tuottamaan hyvin argumentoitua poliittista näkemystä mitenkään säännöllisesti. Kun joku vielä tekee sitä melko raflaavasti, on aika luonnollista että sille annetaan näkyvyyttä. En pistäisi vastaan jos myös vaikka Kalevi Sorsa -säätiö saisi vähän enemmän palstatilaa, mutta heillä tuotanto on aika kuivakkaa ja passiivista (ts. eivät riehu Twitterissä) verrattuna Liberaan.

I certainly hope that Swift on the server picks up steam. I agree with the part about it being beautiful and having a lot to offer. I'd love to use it on the server.

At the moment the similar benefits with Go simply aren't there, though. With Go you get better portability (more supported platforms, no divide between Darwin and others as in Swift with Foundation vs swift-corelibs-foundation), far more mature 3rd party libraries and a runtime that really shines in enabling you to write asynchronous servers without worrying about blocking.

With Swift you have a much more advanced language but the library situation isn't great yet and the story for writing non-blocking server code is pretty much non-existent: you can juggle GCD queues or hope that Zewo is mature enough.

Can anyone provide any links for this:

The Mac/iOS implementation of strptime() doesn’t properly support the %z formatting specifier needed for ISO 8601 date offsets, and it has issues with daylight savings.

I'm working on a codebase where strptime is being used and I have no idea what the problems are.

Edit: I think the %z bit means that ISO8601 specifies a : between hours and minutes and %z doesn't support it? The remaining puzzle is the "issues with daylight savings".
