Xcode 26.5 adds queued AI requests to streamline developer workflows

Apple released Xcode 26.5 on May 11, 2026, with a small update to its coding assistant that changes how developers can interact with AI tools inside the IDE. Apple’s release notes say messages “can now be queued in the coding assistant,” which means a developer can line up another request before the current one finishes. (developer.apple.com) The same update also lets agents ask clarifying questions “to provide more accurate results.” Xcode 26.5 includes Swift 6.3 and SDKs for iOS 26.5, iPadOS 26.5, tvOS 26.5, macOS 26.5 and visionOS 26.5, according to Apple. (developer.apple.com) ### What exactly changed in Xcode 26.5? Apple’s Xcode 26.5 release notes list two coding-intelligence additions under new features: queued messages in the coding assistant and clarifying questions from agents. (developer.apple.com) Apple did not publish a longer product post describing workflow details in the release notes, but the feature wording indicates Xcode now accepts multiple prompts while an earlier request is still being processed. Xcode’s coding assistant is the sidebar interface where developers enter prompts, review responses, start conversations and undo changes, according to Apple’s documentation. (developer.apple.com) Apple says the assistant can work with either an agent or a chat model, depending on what the developer enables in settings. ### Where does this sit in Apple’s AI coding setup? Apple’s documentation says coding intelligence in Xcode is built around third-party agents and chat products rather than an Apple-only model stack. In the Intelligence settings, developers can enable tools including Claude and ChatGPT, and Apple says other providers can also be used. (developer.apple.com) Agents in Xcode can do more than answer questions. Apple says an agent can refine and iterate on a goal, fix build errors after writing code, and use some Xcode capabilities automatically, including building and testing an app. Apple also says developers control what external tools and command-line capabilities an agent may use. (developer.apple.com) ### Why would queued requests matter in practice? A queued-request system changes the pacing of how developers use the assistant. Apple’s previous documentation describes a conversation flow in which prompts are entered and responses appear in the coding assistant, with history preserved so developers can review past responses and return to earlier project states. (developer.apple.com) The new queueing feature adds a way to stack follow-up work inside that same flow rather than waiting for each response serially. That is an inference from Apple’s description of the assistant and the new release-note language. (developer.apple.com) The clarifying-questions feature points in the same direction. Apple says agents can now ask follow-up questions for more accurate results, which suggests more back-and-forth inside a single task before code changes are applied. Apple’s documentation already says Xcode may ask for permission before an agent accesses files or uses a tool. ### Which developers are most likely to notice it first? Teams already using agents inside Xcode are the most direct audience. Apple says developers can choose an agent under “Agents” or a model under “Chat” in the coding assistant, and that agents automatically get access to some Xcode capabilities such as building an app and searching Apple documentation. (developer.apple.com) Developers working on larger codebases may also notice the change because Apple’s coding assistant is designed for tasks such as explaining unfamiliar code, finding files for a new feature, fixing or refactoring code and generating documentation. (developer.apple.com) In those workflows, multiple related prompts often follow one another quickly. Apple’s documents do not quantify expected time savings. ### What else shipped with Xcode 26.5? Xcode 26.5 shipped with StoreKit testing support for a monthly subscription plan with a 12-month commitment, according to Apple’s release notes. Apple also listed fixes for malformed data in a RunSomeTests MCP tool call and an OAuth-token error affecting some users interacting with Claude Code. (developer.apple.com) Apple’s release page lists Xcode 26.5 build 17F42 as the current release dated May 11, 2026. Developers can download the update now and review Apple’s release notes and coding-intelligence documentation for setup details covering Claude Agent, Codex and other supported tools.
