Concurrency, Combine, and Swift 5.5

I started a post that brings together all the moving parts that have been discussed in the various concurrency proposals that are going into Swift 5.5. They’re all accessible through GitHub, and the discussions in the public forums. The combined view of all the moving parts is complex. I was aiming to post something thisContinue reading “Concurrency, Combine, and Swift 5.5”

Why I don’t want Xcode on the iPad — macOS and iPadOS

With the impressive announcement of the latest iPad Pro’s now being available with the M1 chip, seems like a whole lot of people (in the communities I follow) are talking about the announcement with a general theme of “WTF are we going to do with that chip in there?” Often they’re Apple-platform developers and sayingContinue reading “Why I don’t want Xcode on the iPad — macOS and iPadOS”

Translating Java Into Swift

I’m working through the online book Crafting Interpreters, (which I highly recommend, if you’re curious about how such things are built). While going through it, I’m making a stab at translating the example code in the book (which is in Java) into Swift. This is not something I’m very familiar with, so I’m trying aContinue reading “Translating Java Into Swift”

Iterating through Strings in Swift

I recently decided to dive into a new bit of learning – creating my own software language interpreter. No, I’ve not gone stark raving mad due to COVID isolation, it is an interesting challenge that I wanted to understand better. Over a year ago, I remember Gus mentioning the process of creating an online bookContinue reading “Iterating through Strings in Swift”

Nested Observable Objects in SwiftUI

This one often starts with the phrase: Hey, why isn’t my view updating? It shows the initial data, but it doesn’t update when that data gets changed! … more than one person, including me … When you get into seeing the code for the view, how it’s formed, and what the models look like, youContinue reading “Nested Observable Objects in SwiftUI”

Integrating SwiftUI Bindings and Combine

A misconception I had when first learning SwiftUI and Combine was that SwiftUI relied on Combine alone for updating data. There was a throw-away comment in one of the 2019 WWDC presentations (Data Flow through SwiftUI) relating the two, and I over-interpreted it to mean that SwiftUI solely used Combine. To be very clear –Continue reading “Integrating SwiftUI Bindings and Combine”

The evolution of “safe” and “unsafe” in the Swift programming language

There’s been a lot of motion in the last four months of the evolution of the Swift programming language that I’ve been wanting, waiting, and hoping for. The language maintainers are tackling concurrency as a first-class construct in the language. I’m following along with the language evolution proposals in the forums, and so far haveContinue reading “The evolution of “safe” and “unsafe” in the Swift programming language”

M1 arm64 native OpenSSL with vcpkg

This article isn’t a how-to so much as a debugging/dev diary entry for future-me, and any other soul who stumbles into the same (or similar) issues. Let me provide the backdrop for this story: I’m working on a private C++ language based project, previously written to be cross platform (Windows, Linux, and Mac). It hasContinue reading “M1 arm64 native OpenSSL with vcpkg”
