I don't know, I write Swift on a Mac targeting macOS or iOS. I usually have Xcode open to build/run/debug and for documentation lookup, and alternate between that and VSCode for actually writing the code; worst thing about Xc

Swift outside of Xcode is a bit rough around the edges, I think because more attention goes into making Xcode friendly. I opened Xcode, made a new playground, and hit run, the code crashes and highlights the line where the error occurred in

I don't get this reaction. Apple: here, we're open-sourcing this previously closed-source Apple-specific thing that made Swift better on Apple platforms. We're moving the Apple stuff into a plugin so Windows and Linux can be

And/or build a near cache so you treat the 3rd party as a control layer, but actually serve requests from your near cache as data layer. Then when 3rd party goes down, your app doesn’t notice at all, and you can still manually update&#

Software updates happen once per two hours, config changes happen once per 5 minutes or faster. A few days ago I’m tuning performance parameters for a low latency stream processing system, I can iterate in 90 seconds by twiddling some confi

When your app starts to get bigger and more complex, the idea of needing to restart a process to pick up any new kind of data starts to seem silly. Have seen the pattern many times: Hard-code values in code -> configure via env -> con

Often these 3rd party offerings are feature flags PLUS experimentation with user segmenting. Depending on the style of software you build, this can be extremely valuable; it’s very popular in the SaaS market for a reason. Early on at Notion

Python, Java, C#, JavaScript, Go, Ruby all improve so substantially in 3 years time, I can’t square the advantages of using a distro package for any of them versus using at least the latest LTS from upstream. What is so great about the dist

Hence this announcement is great, since it seems to say they’re (going to?) support building GUI apps with SwiftPM and/or the newly open sourced build tool.

Distro packaging for programming language ecosystems is so often hopelessly out of date. I’ve never used a distro toolchain or packages to build production software for any language Python’s age or younger. Outside of C/C++/Fortra

Although opinions inside Apple about Swift vary, they seem to be investing in low level Swift for embedded, kernel use, and programming the “Secure Enclave” subsystem. They certainly have many opportunities to use it for headphones, AirTag,

The reason the zones use city names is because city identity is far more stable than national or regional borders. Still, the system can gracefully handle deprecation of a zone name. If Paris is renamed NewNewYork by edict of some new globa

The notification summaries are good comic relief (only reason I haven’t turned it off), besides that it’s just gimmicks like image generation that never follows my prompt. Very meh.

Well unlike Samsung, Apple has a great user friendly “proper” desktop environment they could teach their mobile devices to run. Plug iPhone into a USB-C monitor and get a full macOS computer and I’d have no complaints. Now, they never will

I didn’t have time to work up a repro, but the issue is a classic one with the basic algorithm you use for your ComputeSignal graph. The issue is that during the fan-out after a change at a root, a ComputeSignal that’s recomputing can read

At least in the JavaScript/NPM ecosystem, “if you want it done right, you have to do it yourself”. Often the most popular package for X is actually low quality and/or obviously incorrect, especially for small-to-medium complexity
