The upcoming OS versions will be iOS 26, iPadOS 26, macOS 26, visionOS 26, tvOS 26, and watchOS 26.
These changes are anticipated to be released by the end of 2025.
This shift from version numbers to years aims to provide a clearer timeline for system updates.
Some concerns are raised around potential confusion with iPhone naming and iOS version numbers.
The move is expected to simplify the process of identifying and tracking software upgrades.
The speculation has spurred varied reactions from tech enthusiasts, with opinions on the aesthetics and practicality of the new naming convention.
It is suggested that the traditional version numbering may still be used in APIs to avoid compatibility issues.
Critics argue that sticking to a one-year development cycle could impact Apple's software quality.
The decision to adopt a year-based naming scheme for OSes may solidify Apple's commitment to annual updates.

Guess Duel: Building a Turn-Based Number Game with PyGame and Amazon Q CLI

Guess Duel is a turn-by-turn, two-player number guessing game created using PyGame with Amazon Q CLI for the Amazon Q CLI Game Challenge.
The game involves an Attacker who hides a number and a Defender who tries to guess it, surviving five increasingly hard levels in Easy, Medium, and Hard difficulties.
During development, the creator faced challenges setting up the project on Windows with WSL for a Linux environment, ultimately shifting to native Windows Python.
Amazon Q CLI helped build the game foundation by defining states like menu, input screens, results viewer, and game over screen.
The game evolved with added features like a health system for the Defender, turn tracking, animated result screens, and hints from level three onwards.
Amazon Q CLI provided efficient code hints for implementing features like level progression tracking and victory messages.
Improvements were made to clarify player roles, enhance UI, and handle PyGame window resizing for optimal player experience.
Small quality-of-life additions such as sounds, music, HP bars, and clickable buttons were included to enhance gameplay.
The project was both educational and entertaining, highlighting the importance of good game state management, design, and collaboration with AI tools.
The game was submitted to the Amazon Q CLI Game Challenge for a T-shirt reward and serves as a learning experience with potential future enhancements like local multiplayer or online features.
