Models like GPT-4 and Claude require less specific prompts and are more adept at understanding intent.
The focus is shifting towards tool integration, workflow design, and system behavior rather than perfecting prompts.
Prompt engineering is evolving into a more productized role, akin to CSS-in-JS or serverless functions.
The future of AI work lies in designing intelligent workflows and orchestrating interactions rather than focusing on phrasing.
New roles are emerging that involve designing intelligent workflows and connecting tools like GPT-4 and Claude for automation.
The role involves blending taste with technology, working with various professionals, and ensuring the output feels right.
The emphasis is on building something sustainable beyond just writing prompts.

WWDC 2025 - Optimize SwiftUI performance with Instruments

Instruments 26 introduces a dedicated SwiftUI instrument to optimize performance by addressing issues like long view body updates and unnecessary view updates.
Common performance problems in SwiftUI apps include delays in animations due to slow view body computations and unnecessary view updates.
The SwiftUI instrument in Instruments 26 offers tracking lanes for Update Groups, Long View Body Updates, Long Representable Updates, and Other Long Updates.
Diagnosing long view body updates involves moving expensive computations out of view bodies and into cached, pre-calculated values to optimize performance.
SwiftUI's declarative nature uses AttributeGraph to manage dependencies between views efficiently and optimize updates.
The Cause & Effect Graph in the new SwiftUI instrument visualizes update relationships, helping identify unnecessary updates for optimization.
Creating granular data dependencies in SwiftUI minimizes unnecessary view updates and optimizes performance effectively.
Avoid storing frequently changing values in the SwiftUI Environment to prevent performance issues across multiple views.
Best practices for optimizing SwiftUI performance include keeping view bodies fast, designing granular data flow, profiling early, and understanding the render loop.
To utilize the new SwiftUI instrument, developers can install Xcode 26 and update test devices to start profiling and optimizing SwiftUI apps for improved performance.

A Beginner's Guide to Promises in JavaScript (with Real Examples)

A Promise in JavaScript is a way to handle asynchronous operations that take time such as fetching data from a server or waiting for a timeout.
A Promise can be in three states: Pending (task not done yet), Resolved (task completed successfully), or Rejected (task failed).
The basic syntax of a Promise involves creating a new Promise object with a resolve and reject function.
An example of using a Promise for a fake API call demonstrates the asynchronous nature of promises.
Chaining Promises allows for sequential execution of asynchronous tasks.
A tip is to think of Promises like a food delivery app where you order, get food when it arrives (resolve), or handle a delivery failure (reject).
Resources like MDN Web Docs and JavaScript.info can help in understanding Promises.
The author initially avoided Promises but found them essential when working with real APIs in React.
For beginners, understanding Promises can simplify handling asynchronous tasks.
Follow the author on Dev.to for more content.
Promises are crucial in JavaScript for managing asynchronous tasks.
Understanding the basics of Promises can enhance coding skills, especially when working with real-world applications.
