< Previously on WatchKit Adventure…

For some reason, after watching WWDC talks mentioning watchOS in the last few years, I had this image in my mind that almost every version changed everything in how apps are built. I remembered something about native and non-native apps, two different types of app schemes in Xcode, and some diagrams of pieces moving from one box to another, on more than one occasion. This all sounded confusing, and I think that’s one reason why I was discouraged from starting, because I imagined it would make it hard for me to catch up with all of that.

As it turned out, this wasn’t really true.

The only change that could be considered major was the move from watchOS 1.0 to 2.0 – it introduced what’s called native apps (somewhat confusingly – since both kinds of apps are native in the usual sense, that they’re written using ObjC and Swift, and not web technologies or some other kind of emulation). But even that, as I understand, was really a smaller change than it appears (though I won’t know for sure). The general architecture, the way you write Watch apps, everything that’s different than what you’re used to from iOS – this all hasn’t really changed since watchOS 1. What’s changed is mostly that apps are faster, can do more work in the background, and have access to more features and frameworks.

Ever since I saw the first Apple Watch announced on stage, I wanted to learn to write apps for it. I bought my first Watch half a year later, when they finally appeared in Europe, with that thought in mind. You can probably guess how that went…

I now have on my wrist my second Apple Watch (Series 1), bought two years ago after I smashed the screen in the first one. And to this day I haven’t written a single line of code for watchOS… This is actually one of many things that have been on my ToDo lists for literally years, that I often think about, but never actually find time to do. Procrastination is a terrible thing.

For the last 3 WWDC’s I’ve been collecting ordered lists of all new features and APIs added in the new releases of Apple’s OSes, either announced in the keynote or one of the talks, or in release notes, or just discovered by some API diff spelunkers :) I’m pretty late with that this year, because I spent some time instead on a couple of longer posts about notifications and Dark Mode, but here it is, just in time for the final launch and the September event.

In general, there seems to be noticeably less changes this year, which is good in a way – it should be easier for us to learn the new things and update our apps. For a moment it even looked like the “macOS SDK” section could be longer than the “iOS SDK” this time with all the Dark Mode changes, but iOS got a boost from the notification APIs and finally finished 3 lines ahead of macOS :)

If you want to learn more about any given topic, the best way is probably either to look it up in the shiny new Apple Developer Documentation (redesigned last year), or watch the recorded WWDC talk videos – either on Apple’s site, or using the great unofficial WWDC Mac app.

Previous editions are available here:

One of the things that caught my attention in the WWDC videos I watched last week were the improvements in the notification system, meant to on one hand give more control over notifications to the users and make them a bit less overwhelming, and on the other hand make them more useful by allowing them to be more interactive.

I’ve tried to sum up here all the changes related to notifications that I’ve found – there’s nothing here that you can’t find by yourself in the videos, but I figured it’s worth putting it all in one place in a concise form.

Most of the below applies to both iOS 12 and watchOS 5.

Apart from a whole bunch of new frameworks (see the whole list here), iOS 11 also makes some major changes to existing APIs. One of the affected areas is location tracking. If your app only uses location while the app is in the foreground, as most apps do, you might not have to change anything at all; however, if it’s one of those apps that continuously track user’s location throughout the day, you should probably book some time this summer for making some changes in how you do the tracking and testing possible usage scenarios.

This post is mostly based on the “What’s New in Location Technologies” talk from WWDC, so if this topic is relevant to you then you should definitely watch the whole talk.

It’s that time of the year again – if you’re like me, you’ve probably spent a lot of time in the last few weeks following everything that’s been announced at WWDC, digging into release notes, watching WWDC talks and playing with some cool new stuff. And as usually, the amount of new things to process is pretty overwhelming.

So like in the last two years, I’ve prepared a nicely organized list for you of all the things I could find from various sources: all the user-facing features in macOS/iOS/watchOS/tvOS, and all new frameworks, APIs and improvements in their respective SDKs and Apple’s developer tools.

To get more info about any specific thing, follow the links above the sections to Apple’s developer site and the “What’s New” documentation, download the release notes from developer.apple.com, and of course use the freshly redesigned unofficial WWDC Mac app to watch the talks that you’re interested in.

If you want to catch up on last year’s notes (e.g. to see what you can use if you drop iOS 9 support in your app), check out these posts:

• WWDC 2016
• WWDC 2015

Following the tradition from last year, here’s my complete list of all interesting features and updates I could find in Apple’s OSes, SDKs and developer tools that were announced at this year’s WWDC. This is based on the keynotes, the “What’s New In …” presentations and some others, Apple’s release notes, and blog posts and tweets that I came across in the last few weeks.

If for some reason you haven’t watched the talks yet, I really recommend watching at least the “State of the Union” and the “What’s New In” intros for the platforms you’re interested in. The unofficial WWDC Mac app is great way to download the videos and keep track of what you’ve already watched.

If you’re interested, here are my WWDC 2015 notes (might be useful if you’re planning to drop support for iOS 8 now and start using some iOS 9 APIs).

Here’s my own list of the interesting stuff announced during this year’s WWDC, collected from the keynotes, various Apple docs, blog posts and tweets.

If you’re planning to watch the videos, I really recommend this Mac app that helps you download and watch them: https://github.com/insidegui/WWDC.
