Xcode 26.5 adds message queuing and clarifying questions for AI coding assistants
Apple released Xcode 26.5 with two new Coding Intelligence features: the ability to queue multiple messages to AI coding assistants without waiting for responses, and agent support for asking clarifying questions before executing tasks. The update builds on agentic coding capabilities introduced in Xcode 26.3, which allowed developers to integrate tools like OpenAI Codex and Anthropic's Claude directly into the IDE.
Xcode 26.5 adds message queuing and clarifying questions for AI coding assistants
Apple released Xcode 26.5 on May 11, 2026, with two new Coding Intelligence features designed to streamline agentic coding workflows. The update enables developers to queue multiple messages to AI assistants and allows agents to ask clarifying questions before executing tasks.
New Coding Intelligence features
According to Apple's Xcode 26.5 release notes, the two additions are:
- Message queuing: Developers can now queue messages in the coding assistant without waiting for the previous response to complete (bug ID 174563016)
- Clarifying questions: Agents can ask clarifying questions before proceeding with tasks to provide more accurate results (bug ID 175182375)
The features build on agentic coding capabilities Apple introduced in Xcode 26.3, which allowed developers to integrate AI tools like OpenAI Codex and Anthropic's Claude Agent directly into Xcode for tasks ranging from writing boilerplate code to updating entire projects based on documentation and file structure.
Context: AI-generated code in production
The update arrives as major tech companies report significant increases in AI-generated code. During Airbnb's Q1 2026 earnings call, the company disclosed that 60% of its new code is now written by AI. Google CEO Sundar Pichai reported in early 2026 that 75% of the company's code was AI-generated, up from 50% in fall 2025.
Additional Xcode 26.5 updates
The release also includes new StoreKit Testing support that allows developers to simulate Apple's monthly subscriptions with 12-month commitments, along with several bug fixes and improvements.
What this means
Message queuing addresses a core friction point in AI-assisted development: developers can now maintain momentum by queuing multiple requests rather than waiting for each response. The clarifying questions feature represents a shift toward more interactive agent workflows, potentially reducing the iterations needed to achieve desired results. These incremental improvements signal Apple's commitment to making Xcode competitive in an IDE market increasingly defined by AI capabilities, though specific adoption metrics for Xcode's AI features remain undisclosed.
