HOW TO SKIP RAILS VALIDATIONS ON SAVE How To Skip Rails Validations On Save. Posted on April 12th, 2013. Of course this is a bad practice, but once in a while you need to skip validations and callbacks when saving a Rails object. 5 REASONS YOU ARE NOT TOO OLD TO LEARN TO CODE A Different Perspective. A 20-year-old coder who’s been coding all his life has a very narrow perspective on life. That’s why they make things like SnapChat. Yes they’re popular, but they’re all targeting other young people.

learn to code?”.

HOW TO MAKE A SIMPLE SPEECH BUBBLE WITH CSS Next, the CSS for the speech bubble rectangle area is pretty simple. Just make a rectangle with rounded corners (if that’s what you want) and add any colors you like. Make sure to add absolute positioning, which is necessary for adding the arrow later. 1. 2. UPDATED: PROTOCOL-ORIENTED MVVM IN SWIFT 2.0 I’ve fallen in love with Protocol-Oriented Programming (POP), but of course, I’m new to it and still learning. One of my favorite use-cases for POP is with MVVM. I wrote about it back in August – read it if you’d like to understand the problem more. Since then, I have of course found an even better way of applying POP to MVVM! A SWIFT LOOK AT PROTOCOLS WITH ASSOCIATED TYPES A Swift Look at Protocols with Associated Types. When I first saw the term “associated types” on Twitter and around the inter-webs, I honestly just ignored it. It seemed very high level. But then two things happened almost at the same time.

FEATURE TESTING WITH KIF IN SWIFT One of the things I’m currently working on is getting back into my old Rails habit of testing my code. With KIF and XCTest frameworks, testing has become a lot simpler in iOS. However, as I started with KIF in my Swift app, I ran into an issue, which was luckily easy enough to resolve.

One of the things I was disappointed with for CloudKit was how Stringly-typed it is – given that this is a relatively new native solution from Apple. I was hoping to see something closer to what Parse did. But it ended up working well with Realm subscripts that way. I think the code can definitely be improved to be less

WATCHCONNECTIVITY: SHARING THE LATEST DATA VIA APPLICATION WatchConnectivity: Say Hello to WCSession. Background data transfers via Application Context should be done when your Watch App only needs to display the latest information available. For example, if your Glance shows the game score, the user doesn’t care that the score was 4-2 two minutes ago. They only care that the current score is 4-4. SWIFT: WHAT ARE PROTOCOLS WITH ASSOCIATED TYPES? Swift: What are Protocols with Associated Types? Posted on July 28th, 2016. I recently gave a talk about Protocols with Associated Types (PATs) – I was worried that my audience would already know everything about PATs, but turns out the opposite is true.. Many didn’t know what PATs were – which I should have anticipated in hindsight, since it took me a while to learn about them myself.

become a problem.

WHEN TO USE MUTATING FUNCTIONS IN SWIFT STRUCTS When To Use Mutating Functions in Swift Structs. Posted on January 13th, 2016. One of the best things about Swift is that it has built-in features that allows for a lot of immutability in the architecture, making our code a lot cleaner and safer (highly recommend this talk on the subject if you haven’t seen it already!)..

You'll learn: Error Handling with Swift 3.0, Protocol-Oriented Programming, Reference vs Value Types, and Higher Order Functions IMPLEMENTATION MATTERS Lately, I've been thinking a lot about functional programming... in

relation to life.

ENDING THIS WEEK IN SWIFT I started This Week in Swift for selfish reasons. In July 2014, Swift was still in Beta, Playgrounds would crash after only 100 lines of code, and we were all still super confused about Optionals... 150 issues later, it is time to end it... THE EASIEST WAY TO GET A URL FOR YOUR APPLE WALLET PASSKIT PASS For try! Swift NYC, we are playing with the idea of adding QR codes to conference badges that will add attendee’s contact information business card to your Wallet app... SWIFT: ALTERNATIVE TO DEFAULT IMPLEMENTATIONS IN PROTOCOLS I recently wrote about why I prefer not to use default implementations in Swift protocols. Here is how you can still optimize using a default implementation without the unintended side-effects... SWIFT: WHY YOU SHOULDN’T USE DEFAULT IMPLEMENTATIONS IN PROTOCOLS Why I decided against a nice refactor... SWIFT: WHEN TO USE GUARD VS IF One thing I’ve noticed recently in my code-base is that I tend to default to guard vs if. In fact, whenever I write an if statement, I facepalm myself and change it to a guard without thinking much. But that’s become a problem. There is in fact a difference between guard and if and thought does need to be put into which one to use. ARCHITECTING FOR FEATURES A few months ago, I gave a talk titled Build Features, Not Apps at iOS Conf SG – you can view the full talk here. It was clearer than ever to me after WWDC 2016 that the future of apps is a web of distributed features instead of one concentrated app. Think of Apple Watch, Today’s Widget, Rich Notifications, App Search, iMessage Stickers, and the list goes on… HOW TO REUSE PAGING INTERFACE CONTROLLERS IN WATCHOS I've been trying to figure out how to reuse the same interface controller code for all my interface controllers in a watchOS paging navigation, and finally did. But this solution comes at a price... CREATING A FRAMEWORK FOR BOTH IOS AND WATCHOS The try! Swift app runs on both iOS and watchOS, and I’d like to expand it to support fancy extensions and possibly something with iMessage. While I was ok duplicating the Model layer between the two platforms initially, as more extensions and platforms are something I want to code quickly on, it was time to move that code out into a

framework.

SWIFT 3.0 REFACTORING CUES I’ve been upgrading the try! Swift app to Swift 3.0 for what feels like 3 days now. But anyway, this morning my BUILD SUCCEEDED!! And although the process was definitely frustrating, a lot of the things that needed fixing were very repetitive and a good opportunity to

refactor...
