Make Xcode 8 Again
There's no doubt that this year's Xcode release is focused on making everything a little bit easier, especially code signing! This article takes a look at some of the highlights from the release notes for Xcode 8.

Our favorite from the Xcode 8 beta 3 Release Notes is actually this polite little convenience:
.xcconfig files support conditional inclusion of other .xcconfig files, using the syntax #include? instead of the usual #include (which still generates a warning if the file is missing, as before). (11003005)
Sweet! As we’ve mentioned before, it’s much more elegant maintainable and trackable to manage your project settings textually, and this makes that just that much more elegant. That’s pretty much the theme of Xcode 8, it seems: make everything that much more elegant. We thoroughly recommend that you go through the release notes with every new release, but If you’ve been to keep up with that, here’s a good TL;DR on the high points:
- Swift 2 and 3
- Up until Xcode 8, every version of Xcode was tied to a specific version of the Swift programming language. That is no longer true as of Xcode 8. Swift 3 introduces a slew of changes and a considerable number of these changes are breaking…
- Source Editor Extensions
- Developers have been asking for a native plugin architecture for many years. Source editor extensions are a first good step in that direction… [However, note that Alcatraz is dead, so this is a mixed blessing at best -Ed.]
- View debugging is much more powerful in Xcode 8. Reliability has improved and debugging ambiguous or unsatisfiable layouts is much easier thanks to an improved view debugger that displays runtime issues … Xcode 8 also sports a pretty impressive memory debugger for tracking down memory leaks and retain cycles…
- Code Signing
- Code signing issues should be a thing of the past with Xcode 8 … I hope Apple got it right this time. And with me tens of thousands of other developers.
- Other Improvements and Enhancements
- San Francisco Mono; Line Highlighting; Code Completion for Images
- The new documentation format looks gorgeous and the documentation browser is fast and easy to use. Apple also consolidated the documentation for its platforms, resulting in a much smaller memory footprint….
There’s a longer list as part of this veritable encyclopedic collection of "What’s New In Everything":
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…
We’ll go out on a limb here and predict that the thing mentioned here you’re most interested in a deeper dive into is code signing. And here’s a discussion of team implications, and here’s an optimistic article going into thorough background detail:
Code signing and managing provisioning profiles has been an ongoing annoyance for many developers over the years. I have written and spoken extensively to help people understand what code signing and provisioning profiles are and how they can be better managed. So, you can imagine my surprise and excitement when Matthew Firlik mentioned code signing and provisioning during the Platforms State of the Union (53:30) at this year’s WWDC. It was also revealed that the schedule contained an entire session, What’s New in Xcode App Signing, and two Labs dedicated to the topic. So, does Xcode 8 solve all of my code signing and provisioning profile grievances? Pretty much…
And if you still want more, there’s details and discussions collected over at Michael Tsai’s Xcode 8 Tips and Issues.
