Molly K. Maskrey has been actively using the Swift language since its release, not only in iOS projects but in non-iOS projects as well since Swift became an open source language. Molly began her career programming COBOL on IBM System/360 computers at banks in and around Tampa, Florida while getting her undergraduate degree. From there, she moved on to work for various large Aerospace companies including IBM Federal Systems, TRW (now Northrup-Grumman), Loral Systems, Lockheed-Martin, and Boeing. In 2010 she co-founded Global Tek Labs, an iOS development and accessory design services company that is now one of the leading consulting services for new designers looking to create smart attachments to Apple devices. Molly wrote the Swift 3 version of this book and App Development Recipes for iOS and Apple Watch. Molly lives in beautiful Colorado and you will either find her on the ballroom dance floor or a rooftop patio.
