Removing Publicist

May 05, 2021 - 409 words - 3 mins
Publicist first arrived in the app store on April 14, 2019. Now, a little more than two years later, I'm removing it. Publicist started as a free app with a subscription model to support it.

Here are 5 APIs provided by Apple that you may not know about: 1. SearchKit SearchKit is a C-level API that provides quick full-text search for your Mac apps. I've seen many questions about how to enable the full-text search extension in SQLite to use in CoreData or how to install and setup some thi… read more

Buttons Over Views

October 20, 2020 - 259 words - 2 mins
One enemy of accessible apps is the use of views instead of buttons. A button, UIButton or NSButton, handles taps and clicks from users. For users who have trouble doing that, iOS and MacOS have accessibility support to enable those users to get their work done. Many developers (me included before) … read more

JSON Handling

Strong Self in Swift

September 18, 2018 - 298 words - 2 mins
Swift 4.2 has arrived which gives us the ability to replace code bits in your weak-reference blocks like guard let strongSelf = self else { return } or guard let 'self' = self else { return } with new-fangled, more direct things like guard let self = self else { return }.

Diversity

July 14, 2018 - 623 words - 4 mins
We in the Apple-platform space suffer from a lack of diversity in our conferences. I’ve seen this vastly improve in the US, but over here in Europe it still seems fairly bad.

Wacky JSON

January 23, 2018 - 524 words - 3 mins
In Swift, turning JSON content from a file or a server into structs or classes in code is much friendlier now that we have the Encodable and Decodable protocols. For simple cases you need to write almost no code and can quickly get on to something else. For example, if you see this: { "posts… read more

Intelligence

December 18, 2013 - 420 words - 3 mins
Words like “intelligent” and “stupid” and “smart” and “genius” get thrown around quite a lot these days. I think they’re all mostly bullshit and distract from the real issues. In software, we often run into people who lack the depth of knowledge and experience in the various fields necessary to make… read more

#define

When to use #define: When you’re declaring macros like in Apple’s: #define UI_USER_INTERFACE_IDIOM() ([[UIDevice currentDevice] respondsToSelector:@selector(userInterfaceIdiom)] ? [[UIDevice currentDevice] userInterfaceIdiom] : UIUserInterfaceIdiomPhone) I’m actually not even sure why this was… read more

Duck Types and Objective-C

November 25, 2013 - 472 words - 3 mins
I just finished the book, Practical Object Oriented Design in Ruby. I haven’t been paid to write Ruby code in years and I still found the book incredibly useful. Sandy Metz writes excellent explanations for many things I have felt about code I have seen while working on projects. In the last chapter… read more

Capacity

October 31, 2013 - 570 words - 3 mins
I try to be extra careful to consider my capacity before agreeing to do something for or with someone (or even for myself). Mis-judging capacity seems to often be the cause of frustration and failure. I think now I finally have the capacity to do something cool that isn’t for a client. I think about… read more

How to get started with remote pairing quickly

October 22, 2013 - 957 words - 5 mins
Remote Pair Programming is a thing now that people do. Basically, it enables you to learn from and work with anyone anywhere, ever. You can do that thing we love to do (write code) with a diverse range of people. So let’s say you’ve decided you like this idea of getting out of the bubble of programm… read more

Make Git Friendlier: status

August 05, 2013 - 207 words - 2 mins
Since I couldn’t sleep tonight, I watched a presentation by this guy Zach Holman who works for GitHub. One tip he shares makes the output from git status much friendlier and I thought I’d share it so you don’t have to watch an hour of talking to find out about it. Instead of: git status try typing… read more

Community

June 13, 2013 - 226 words - 2 mins
Being a part of Appsterdam and trying again to run my own business has made me think differently about community.

Failure

February 20, 2013 - 629 words - 4 mins
It is becoming popular, especially in American tech culture, to encourage failure as a natural part of learning and a key to success. Humans fail in many casual ways to learn basically anything, even basic skills like walking. Failure in software is often expected on a very minor level. Maybe I’ll r… read more

Web Developer Admits: Objective-C > HTML5

Web Developer Admits: Objective-C > HTML5 "It felt like hammering nails into in a wonky floorboard. We fixed one problem and another would pop up.

Down with NSLog

December 06, 2012 - 485 words - 3 mins
NSLog is a fun debug tool, but it has no place living in your version control history. Those of you who came from other languages and platforms might be used to a world where NSLog’s cousins, console.log, print, puts, and the sort were all you had to try to figure out what was wrong with your code. … read more

No Comments Left Behind

December 01, 2012 - 357 words - 2 mins
I would like to explain my hatred for commented-out code. Some might call this hatred extreme. They’re probably right. When I look at code interspersed with commented-out lines, I think of my own home which is often covered in dog hair. Now my dog is adorable, but he does in fact shed quite a bit. … read more

Switches Get Stitches

November 19, 2012 - 819 words - 5 mins
We have a new rule here at Roundwall Software: switches get stitches. Switches and if statements can easily pile up in a method and make it difficult for someone to understand what a method does. They also makes testing harder because tests that cover a method need to cover every possible branch pat… read more

Code Examples

November 15, 2012 - 301 words - 2 mins
The point of sample code is to show you just enough code to communicate a concept. Sometimes code for a given demonstration (such as showing how to use parts CoreData or CoreText) requires a bit of boilerplate in order to show the concept. For example, let’s consider a sample project to demonstrate … read more

External Storage with Core Data

New since iOS 5.0, we have a new weapon at our disposal for Core Data.

A Massive Speed Difference In iPhone CoreData

October 19, 2012 - 397 words - 2 mins
It was brought to my attention last night by my good friend, Collin Donnel, that using a fetch request to grab objects based on their objectID’s was much slower than simply using a for loop and the NSManagedObjectContext method -existingObjectWithID:error: to grab each object one by one.

No more SOLID

March 13, 2012 - 152 words - 1 mins
The more I research these SOLID principles, the more I see how they don’t necessarily apply to modern programming and even less so to Objective-C.
