Code With Jim

I have a big curiosity on how we can use OSC or MIDI to send message from one app to another app, potentially to generate (realtime) synth sound, visualization, and animation. This is especially a fun area and environment when we wanted to use CODE for CREATIVITY. Sonic Pi (by Sam Aaron) is one app I really love to use when dealing with Synth and Sonic generator. I remember using ChucK in the past by Ge Wang, ChucK is also cool, but Sonic Pi is a lot more friendly. http://sonic-pi.net Sonic Pi multi-threaded ness and LIVE LOOP is really something new for me. But Sam made it easy enough so that we could generate "listener" very easily. MAKING SOUND WITH CODE There are plenty of ways we can "trigger" Sonic Pi to generate sound. Obviously we can just use the built in RUBY language inside Sonic Pi app. Fairly simple and fun language to use and you can generate some noise in no time! Sonic Pi RUBY language documentation is really in depth and a full on progr...

Using Apple  Swift Playground  for the first time is actually quite an interesting experience. There are so many different paths to get HERE, especially when nobody actually guides you. You might be on your own, but you can always try Google Search and look for example and video tutorials on YouTube. Over the past few years, Apple has introduced all these cool tools that probably confuse people at first, but actually make sense today in 2017. I really have to dig into older WWDC as far as 2013 and see what Apple is trying to do. As a total beginner to App Development environment and all kind of actual coding and building interface, control, logics, there are A LOT to make sense. SWIFT PLAYGROUND AS JUMPING STONES I think, THE MOST IDEAL path of actually getting into Apple XCode app development via SWIFT PLAYGROUND is like this: 1) Start with Swift Playground on iPad, not XCode! For beginner coders, whatever your age, maybe even for those who never code b...

I am thinking to write a series of article blog on developing iOS app, but in term of experimental and educational level. No aim in particular, but I think documenting my baby steps with iOS app development might actually help others. MORE FUN THAN I THOUGHT Being exposed to Apple XCode for the first time (version 9 beta I am using) and Swift 4, and also iPhone capability to do Augmented Reality , really bring a whole lot of fun area I can explore. Even as 3D artist with little programming knowledge like me, I can say that it just takes a bit of effort and motivation to brave yourself and try the app creation. Even if you are not going to make paid app, the act to actually make your iOS device to work for you using your own custom app is amazing. Making program for desktop computer VS making apps for mobile device is a totally different set of skill, in a sense that for mobile device (comes with powerful camera, wifi, bluetooth, AR capable, GPS capable and a lot more) you hav...

Saving FILE / DOCUMENT that you generate using your iOS app is an interesting task when developing iOS App. Eventually you also want to know this ability. You can apparently very quickly save out text files, or output all kind of processed files, etc. into Document sandbox of your app, for later to be accessible via iTunes or NEW Files app (iOS 11)! WRITE https://www.hackingwithswift.com/example-code/strings/how-to-save-a-string-to-a-file-on-disk-with-writeto CUSTOM URL You need to prepare your URL Scheme for your app first. This will be handy at later stage. http://jayeshkawli.ghost.io/ios-custom-url-schemes/ PLIST Then we got to deal with PLIST attributions. This is pretty easy once understood. http://pinkstone.co.uk/how-to-enable-itunes-file-sharing-in-your-ios-app/ https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/iPhoneOSKeys.html#//apple_ref/doc/uid/TP40009252-SW20 https://developer.apple.com/librar...

At some point, it would be useful to understand how Swift can generate DATE and TIME data for you. Especially when taking a snapshot or screenshot on the fly and wanting to save the file. Quick browsing leads me to this: http://www.globalnerdy.com/2015/01/26/how-to-work-with-dates-and-times-in-swift-part-one/ https://stackoverflow.com/questions/28016578/swift-how-to-create-a-date-time-stamp-and-format-as-iso-8601-rfc-3339-utc-tim Just like MacOS does SCREENSHOT Cmd+Shift+3, this will become handy.

I am interested to use Animation and Easing for Sprite for my experimental iOS App. Quick search and stumbled into this Sprite Kit Easing Swift repository at Github. https://github.com/craiggrummitt/SpriteKitEasingSwift My thought is that we can probably use preset animation action that Apple provided, but this one add more. I should actually try the default first. But eventually I know I will be using some of these extra actions. This is entering yet another NEW things! I am discovering something called CocoaPods . Somekind of way to manage versions of dependency when we are using some kind of extension. Read CocoaPods documentation here: https://guides.cocoapods.org/using/using-cocoapods.html Ok so my step by step is like this: - Install CocoaPods, easy enough, via Terminal - Then create Podfile inside the project - Install the Podfile dependency, etc. - All good, we should have a new XCode Workspace (!) that we open the next time we want to run the project with Pod...
