I’m still working on that comic book collecting app! It’s starting to look and feel like a real app but still has a long journey of test driven development ahead of it! Here’s what it looks like so far… On the left is the Summary View and on the right is the Detail View. The… Continue reading Book Binder App Update: Variant Chaos!
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 Last night I got a “Identity used to sign the executable is no… Continue reading Identity used to sign executable no longer valid
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… Continue reading Fun with Core Graphics and Swift Part 2
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… Continue reading Fun with Core Graphics and Swift
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… Continue reading Nothing Changes More Swiftly than Apple’s Swift Syntax
If youâ€™re new to iOS game development now is a great time to get started. In 2008 a brilliant engineer named Ricardo Quesada rewrote his 2D game engine for Appleâ€™s iOS and released it as open source. Itâ€™s no exaggeration to say that hundreds of games, like my own, were developed using Cocos2Dâ€”including dozens of… Continue reading Cocos2D-Swift 3.0: A great way to get started developing iOS games!
I spent more time that I care to admit figuring out how to reconcile my old Dungeonators code with Apple’s Sprite Kit, Retina displays, and iOS 7. Along the way I searched the web for help and ran into tons of tutorials and advice for indy game developers (I highly recommendÂ Â www.raywenderlich.comÂ for a great set of… Continue reading Sprite Kit, Retina, iOS7 and Getting It Right
One thing I think all software developers love to do is to make software for “the heck of it.” Hacking something together without having to worry about users, open source community members, and code reviews, is something devs don’t get to do often in these days of test-driven, agile, minimum viable products. Back in 2011… Continue reading Re-doing Dungeonators
There is nothing quite like real user feedback. The Dungeonators game that I started coding about a year ago has been through several design iterations. Before I wrote a line of code I mocked up the whole UI and tested that on my friends and kids (paper prototype, an honorable UI design tradition). And with… Continue reading Dungeonators Battle UI Redesign
