This month is an open discussion. People of all skill levels are encouraged to ask questions about Mac, iPhone, iPad, Apple Watch, Apple TV, or Swift. We will also discuss topics for 2017 so let us know what you would like to learn at a future CocoaHeads meeting. Notice that this month’s meeting is one week earlier due to the holidays.


This month Bill Morefield @bmorefield will demonstrate the basics of what Electron is and how to create desktops apps using HTML, CSS, and JavaScript that can run native on Mac, Windows, and Linux. More information about the Electron platform is available at


Joshua Miller will discuss the importance of iOS 10 sticker packs and iMessage apps for businesses of all types. He will demonstrate the easiest method for creating an iOS 10 sticker pack using Sketch and transitioning to Xcode for testing. Additional in-depth options for stickers exist including in-app purchases and wrapping the iMessage app into an existing package.


Since the quarterly KnoxDevs event is the same week as CocoaHeads, we encourage everyone to attend the KnoxDevs meeting on September 20th to support the local tech community.


This month we’ll talk about Firebase and give away a ticket to Indie DevStock in Nashville. Firebase has evolved into a full backend service to provide developers with authentication, storage, analytics, notifications, a realtime database, and other useful tools. Gavin Wiggins, @wigging, will give an overview of the service along with a demo of Firebase features on iOS. This month we will also give away a ticket (valued at $570) to the upcoming Indie DevStock in Nashville on September 16-17. Don’t worry if you don’t win the ticket, we also have discount codes for registration. You must attend the meeting for a chance to win the ticket or get a discount code.


To support the local tech community, we encourage everyone to attend the CodeStock conference in downtown Knoxville this month on July 15 and 16. You can purchase your tickets at We will resume our usual monthly meetings at the Knoxville Entrepreneur Center in August.


We’ll have Bill Morefield,@bmorefield, discuss Xamarin for building native Android, iOS, and Windows apps using a shared C# codebase. Anything you can do in Objective-C, Swift, or Java you can do in C# with Xamarin. Visit for more information.


We don’t have any presentations scheduled for this month, so leave a comment on Meetup of what you would like to talk about. If enough people show up, we’ll raffle off another Big Nerd Ranch book.


This month we will have a presentation about using NSUserDefaults in Swift by Gavin Wiggins. The NSUserDefaults class provides an interface to the user defaults database for Mac and iOS apps. The most common use of this class is for storing user preferences that will persist between app launches or when the device is shutdown.


This month we’ll have a presention on Couchbase by Mike Hagedorn and an overview of Markdown editors by Bill Morefield.


David Levi will give an overview of CloudKit, Parse, and Deployd as a backend for iOS apps. His demo application is available on GitHub.
