  • Book Binder Update

    My comic book collection iOS app continues to evolve. I continue to strip out features and focus on the core mission: Buy a comic, snap a photo, add it to your collection. With that in mind the UX now looks a lot like a photo app that has been preconfigured for storing comic book metadata.…

  • Emoji Tac Toe Opened Sourced

    Happy Father’s Day!   To celebrate my 28th Father’s Day I’ve opened sourced Emoji Tac Toe. It’s actually not a big deal to anyone but me. It’s kinda of scary open sourcing code that you wrote alone and without first cleaning it up. But what the heck. If someone can learn something from this code,…

  • JavaScript, Swift, and Kotlin Oh My!

    This blog post now lives on http://blog.viacom.tech/2017/05/31/the-co-evolution-of-javascript-swift-and-kotlin/  (and it’s much shorter and better!)  

  • Code Markup in Xcode

    I’m working on  a fairly large Swift project. Actually no, that’s not quite true. I’m working on  a Swift project with a ViewController file that is getting disorganized and out of control. If this keeps up I might have a large project on my hands but right now it’s just a single file that is…

  • Identity used to sign executable no longer valid

    The last thing I wanted to do on a Sunday morning is write a blog post about an an Xcode executable problem. What I had planned to do is test my most recent Swift 2.0 SpriteKit game on my iPad and iPhone. Last night I got a “Identity used to sign the executable is no…

  • Four Tips for Xcode Storyboard Users

    Apple’s Xcode Storyboard is both your best friend and your worst enemy when it comes to developing state-of-the-art iOS, Mac OS X, tvOS, and watchOS apps. Sometimes, what would be really hard, like associating a function with a gesture is quick and easy. Sometimes, what should be easy, like toggling a property,  requires hunting down…

  • Fun with Core Graphics and Swift Part 2

    Hey, you have 10 minuets, don’t you? Then you can add pinch and rotate gestures to our fake-genigraphics app. I didn’t realize it would be this easy. But sometimes Apple’s developer tools engineering team does something amazing–and gesture recognizers are super amazing. A good way to start is to read the UIGestureRecognizer Tutorial on Ray…

  • Fun with Core Graphics and Swift

    A long time ago in a galaxy far, far away… I was a computer graphics artist. Specifically I was a Genigraphics console operator. I worked the night shift creating illustrations and slides with vector graphics for big corporations. This was the early 1980s and fast, cheap personal computers with color graphics had not quite been…

  • The Secret to Swift is Enums

    I’ve found the CS193P (Developing iOS 8 Apps with Swift) iTuneU class really helpful in wrapping my old Objective-C head around Apple’s new Swift programming language. Yes, I know we’re at iOS9 but the fundamentals of the class are still relevant and coaxing the code to compile in iOS 9/Swift 2.0 is a fun little…

  • Nothing Changes More Swiftly than Apple’s Swift Syntax

    I’m enjoying the Stanford University class CS193P: Developing iOS 8 Applications with Swift. It’s free on iTunes U and the instructor Paul Hegarty knows his stuff. He’s a great explainer. I like how first he writes some code in a naive way and then fools around with it, getting it to work and then reworking…
