There were quite a few things that were interesting during the WWDC keynote and some of the sessions that followed. The message throughout the keynote was primarily based on privacy, security, and stability. And this not only makes sense but should be applauded, considering the issues many have experienced with questionable upgrades and lack of stability within the features provided (though not all have experienced such issues that appear to be inflated). For all three operating systems it appears that it's not simply the underlying stability that's being added but also a great deal of additional functionality.
The new OS X El Capitan provides interesting new features such as Split View, and advancements to Notes, Mission Control, Maps, and Spotlight. It's not that new apps were added it's the great deal of new functionality added to apps already on Macs. Apps that I could see myself using as my primary basis and not necessarily gravitating toward purchasing others that simply aren't necessary for me to have based on functionality that may not be essentially a need. The new feature set can be seen here.
iOS 9 brings a lot of under the hood improvements as well but like El Capitan there are a few other features and services that I find intriguing such as News, a new experience for the iPad in split screen apps, and the growing intelligence of Siri. I consume a lot of content on my iPad Air 2 all while creating deal of content as well (a portion of this piece written on my iPhone 6, iPad Air 2, and my MacBook Air). Though I'm curious how my magazine subscriptions will carry over to the news app and how content will be presented overall only the rss feeds of the magazine apps or some additional feature and/or information. Though with the notes app being updated to add drawing features along with everything else I'm hoping the rumored Apple Pen becomes a reality. Go here to learn more about iOS 9.
watchOS 2 brings along a few features we heard about when the watch was first introduced in September 2014, though the ability for app developers to make "complications" for the watch to provide at a glance features is something I'm looking forward to getting my hands on. This isn't simple to understand but consider providing context to fully featured apps where the status of the information is available on the watch face, this isn't entirely simple to conceptualize though I'm looking for ways where an app I'm currently developing can be added on the watch in an efficient manner as well as what type of glance would be necessary if at all. The site gives a pretty solid run down of features listed and can be read here.
Two weeks later there's a great deal to unpack, including a feature that I'm currently researching in depth with regards to Bitcode where apps can be written and work on unannounced devices but goes much deeper than that where some of that depth can be read here for further analysis and my overall interest is substantially high considering what Apple may conceivably announce un the future regarding potential ARM enabled MacBooks that may come sooner than many expect and place Intel in an interesting position. Chips for MacBooks is an interesting proposition, where the A & M series come to the iPhone and iPad, S series come to the Apple Watch, I'm simply curious of the naming scheme of the Apple designed chips coming to the laptops.
In the end the event was interesting and had a great deal of good things coming through, I'll touch up on the music piece later though I'd argue that there was nothing wrong with what was announced except how it was presented (Cue's "dad" dancing could've/should've been shelved but it's cool). There's also tvKit that many are cautiously optimistic and waiting for, maybe WWDC 2016 along with features for newly designed iPhones that may possibly break tradition.
