jtbrown | 8 years ago | on: The biggest mistake new iOS developers make when coding

You're absolutely right — I just know the iOS dev world best at this point.

jtbrown | 8 years ago | on: Why iOS developers don't write unit tests

I agree — I think testable code is generally just better code because it requires the decoupling of dependencies.

jtbrown | 10 years ago | on: Building RESTful JSON Apps in Swift

Hey, everyone! I'm Josh Brown and I co-created this course. I'd love to answer any questions you have about how it works -- or about REST & JSON in Swift in general.

Here's one of our most common questions so far:

> What medium is this course in? Youtube? PDFs that I can read through?

The lessons come via email, and we're going to have a Live Q&A chat on GrokSwift.com towards the end of the course.

We've put a lot into this, and we hope you love it!

jtbrown | 10 years ago | on: Debunking the myths about parsing JSON in Swift

If you're talking about either the bad (pyramid of doom) code in Myth #1 - or the good code there, then it is indeed protecting against null values in the JSON. When you try to cast with `as? String`, it returns nil when there's a null value in the JSON and the code in the `if` block is skipped (and the `else` block is executed if one exists).

Wait... who told you I was writing that book? Just wait till you read next week's article: "Debunking the myths about networking in Swift"

jtbrown | 10 years ago | on: Parsing JSON in Swift

I'm the author, and I'd love to hear what you think and answer any questions you have.

jtbrown | 11 years ago | on: What third-party libraries do you use for iOS development?

Here are some of my favorites - what others do you like?

jtbrown | 12 years ago | on: How to become a professional iOS developer

I'd be happy to hear your thoughts. What's good, bad, right, wrong, or missing? Do you need a Computer Science degree?

jtbrown | 12 years ago | on: Can you learn Objective-C without knowing C?

I'd be happy to hear your thoughts - whether you agree or not.

jtbrown | 12 years ago | on: How I Reduced a View Controller by ~100 Lines (from 400 to 300)

And I'd love to hear your thoughts. Do you think this is better than shoving everything into the view controller?

jtbrown | 12 years ago | on: Want to build your first iOS app? Start here.

I'm here and happy to answer any questions you have about getting started with iOS.

jtbrown | 12 years ago | on: The right way to check the iOS version in an app

I'm here to discuss anything you disagree with or have questions about.

jtbrown | 12 years ago | on: Screencast: Basic Unit Testing in Objective-C with XCTest

If you want to learn the basics of testing with the XCTest framework in Objective-C, this screencast is a good way to start.

jtbrown | 12 years ago | on: Replacing Regular Expressions in an Xcode project

Not sure why it took me so long to find the Replace Regex feature in Xcode...but it's really powerful and useful.

jtbrown | 12 years ago | on: Coffee, Tea, iPhone App: One of These Things is Not Like the Other

I totally agree that comparing a cup of coffee to an app is ridiculous, even if they cost the same. And I think you're right - it's because a cup of coffee is a known thing.

jtbrown | 12 years ago | on: Git Pro Tip: How to List Tags that Contain a Commit with Git

I use this all the time to find out what bugs are where - whether they've made it to staging or production yet.

jtbrown | 12 years ago | on: Ask HN: What don't you like about iOS 7?

Apple has been inconsistent about the use of colors and buttons - sometimes two things look the same, but one's tappable and one's not.

jtbrown | 12 years ago | on: Developing for iOS 7 and supporting iOS 6

Good points about Evernote - I'm not sure what went into their decision to support iOS 7 only, but I'm sure they considered it.

"I guess I was lucky that I still had it on my phone cause otherwise, I would be left without the ability to install it now."

That's not entirely true any more - Apple is now allowing users to install the "last compatible version" of apps. More on that from Engadget: http://www.engadget.com/2013/09/17/apple-ios-last-compatible...

jtbrown | 12 years ago | on: Developing for iOS 7 and supporting iOS 6

Eventually, yes, most users upgrade. But Apple's stats showed about 6% of users still on iOS 5 a full year after iOS 6 was released. I'd imagine we'll see similar numbers with users going from iOS 6 to 7 - lots of them won't upgrade for a full year, and some will never upgrade. Mixpanel is currently showing 36% of users on iOS 6 - that's not an insignificant number. I'll be supporting iOS 6 for probably another year.

Yeah, that navbar issue killed my productivity for at least a day. Glad I finally found the topLayoutGuide property so I can align my views properly.
