Third-party tools aren't ideal—but they're essential. Apple's never solved SwiftUI testing. The community has. Meet ViewInspector. https://qualitycoding.org/viewinspector-risks-benefits/

Previews Aren't Enough: Why SwiftUI Testing Needs Automation https://qualitycoding.org/viewinspector-risks-benefits/

Finally! Discovered thanks to running SwiftFormat over this project. Swift 6.2 means you can write backtick test names (like Kotlin).

Why ViewInspector Is Essential for SwiftUI Unit Testing https://qualitycoding.org/viewinspector-risks-benefits/

To whoever did this at the #NoKings in Boston: Thank you.❤️ It made me tear up. And we must to be reminded of needless damage to humanity that results directly from the careless, bellicose bluster coming from the Pentagon and White House.

"Taming MVC with Model View Presenter" Untamed MVC leads to "massive view controller". While MVVM is a popular alternative among iOS developers, Jon will show his favorite approach: Model View Presenter. https://www.youtube.com/watch?v=iIcGunopmfQ

It's finally time for me to make my next video demonstrating TDD with SwiftUI. I reviewed a scratch video from 7 months ago. I was shocked to see that the AI tool I was using then was GitHub Copilot: not much more than single-line completion!

I'm looking for Ottawa/Gatineau folks willing to help me with some office space. I am thinking of scheduling a remote workshop that would run 2 hours on 2 consecutive days, particularly May 12 and 13.

Is TDD worth the extra effort? A developer learning to apply Test-Driven Development to iOS for the first time shares his testimonial in a blog post. https://qualitycoding.org/is-tdd-worth-it/

👋 Guess who's finally back and ready to restart "Swift + AI" live coding on Sundays? 9:00am Pacific, 16:00 UTC. https://qualitycoding.org/tdd-swiftui-lets-begin/

Do you use Xcode's "Unit Test Case Class" for new files? It's full of noise and waste. Go lean and save time by using my template instead. https://qualitycoding.org/swift-unit-testing-template/

Ugh, computer in the shop — for a week!

ApprovalTests is a new testing tool for Swift, providing an alternative to assertions. Watch this 5-minute demo to learn the basics of getting started. https://qualitycoding.org/approvaltests-swift-getting-started/

“Christ Breaks the Rifle” by kellylatimoreicons.com

I'm starting a new iOS app, and feel like I already have several things to blog about. But first, a micro-blog: - I want the Swift Package to contain all non-UI code. - Incredible feedback speed compared to testing in iOS simulator! - Many think "unit tests" means each type needs a test file. Nope.

🤷🏿‍♂️The backflips white people go through to try to justify police killing unarmed Black people for no reason while opposing ICE killing unarmed white people for no reason, is something quite amazing to observe. Cops have killed 141 people so far this year. It's not even March yet.

Is unit testing view controllers worth it? What about other code that interacts with system APIs? I have a powerful, but non-obvious motive. https://qualitycoding.org/testing-view-controllers/

Developers, managers, executives: If you don’t understand what Jason is saying here, _please be curious enough to ask._

New in Print - and 40% off with code in 🧵 The Healthy Programmer - 2nd Edition. It's a brutal time to be a developer: rising uncertainty, relentless pressure, and constant overload aren't exactly a recipe for good health. Taking care of yourself never mattered more. pragprog.com/titles/...

Test-Driven Development helps me write code that is correct. SwiftLint helps me write code that is clear. Here's how I like to configure SwiftLint. https://qualitycoding.org/swiftlint/

Let's throw a cat among the pigeons. Folks say the difference between software design and architecture is that architecture is design decisions that are difficult to change. A primary goal of software design is ease of change. Software architecture is a failure of software design? Discuss ;-)

"AI has removed the developer bottleneck" If developers really were your bottleneck, throwing developers at a problem would actually have worked in the past 20 years

One point I make is that Agile Software Development's reputation is built almost entirely on the experiences of teams who've never even seen software agility. See also: TDD, refactoring, design principles, continuous integration etc.

A feature of ApprovalTests called "combination approvals" can help you bring legacy code under test. Write tens or hundreds of test cases in a few lines. https://qualitycoding.org/wrangle-legacy-code-combination-approvals/

A large-scale study of developer IDE activity found that only 8% of devs who claimed they did Test-Driven Development did anything even close in reality. Were 92% lying? I suspect not. More likely, they just didn't know they weren't doing it, because they didn't know what TDD actually looks like.

Highlighting the speaker who stood in front of the Surprise mayor and told him to consider what the Mayor of Ohrdruf must’ve thought before he died by suicide: “He might have thought ‘how is this my fault I had no jurisdiction over this’ maybe he said ‘this site was not subject to local zoning.’”

Andrea Bocelli holy moly! #olympics

What does refactoring actually look like? Let's continue an example based on a real iOS view controller. Watch this 23-minute screencast. https://qualitycoding.org/refactoring-mvvm-part2/

Darn. I caught a cold …from going into the office. Tomorrow's live-coding may or may not happen. Let's see how I feel (and sound).

🥶 ❄️ ☃️ It has been COLD in the US this week. Saturday, Brimson Minnesota was -43˚F (-42˚C) So, until the end of the week, pretty much everything is -43% at the Bookshelf. Just use coupon code Brrr when you check out. Stay Warm. Only at pragprog.com ­

What can we do when Swift refuses to create an object we need for testing? This example shows a clever workaround so we can microtest scene delegates. https://qualitycoding.org/unit-test-scene-delegates/

How do you measure productivity? Let’s start by talking about the engineering obsession with quantitative metrics. You can easily measure productivity on an assembly line. The faster a car comes off the line at a given quality level, the more productive you are. 1/10

Join me on my Sunday live-coding as I start a new thing I'm calling "Swift + AI with TDD" 9am Pacific, 17:00 UTC http://twitch.tv/qcoding

AppCode is dead. Long live… what, exactly? https://qualitycoding.org/appcode-is-dead/

The inevitability of AI is now under threat from no one wanting to use it.

A funny thing I observe at work: - colleague opens PR, asks for reviews - I switch to their branch and run tests. And some fail! - I report this to my colleague - They ask, "Which tests failed?" If makes some sense if tests are a thing you avoid. But to me, tests are scaffolding to help me work.

Bugs are opportunities. How can you get the most value from the next defect you fix? https://qualitycoding.org/safety-nets-guardrails/

I'm canceling tomorrow's live-coding. Hey, grandkids take priority.

Cleaning out a drawer, I found my old AppCode t-shirt. It's been 3 years since the only JetBrains IDE for Apple development was killed. It still has no substitute. AI tools can do some refactoring, but not: - provably - deterministically - locally - in a single keystroke that expresses my intention

If something is hard to TDD, what does it say about the design? A bad example from Apple leads us to explore design sense, SRP, and Clean Architecture. https://qualitycoding.org/design-sense/

I'm shaking things up in January. 1. Remote training bookings confirmed by Jan 31st are HALF PRICE. Save ££££ if you're planning training in the next few months. 2. All courses now have modules focused on applying code craft practices in AI-assisted wotshisface. Details at codemanship.co.uk

I'll be speaking on ADHD and Software Development at SeattleJS on Wednesday, Jan. 14th Come join us for a great meetup! www.meetup.com/seattlejs/ev...
