Apple is releasing a second version of Xcode 26.3 that will include agent coding features. Here are the details.
Xcode 26.3 is getting a second release candidate
Earlier this month, Apple announced that Xcode 26.3 will gain agent coding capabilities that natively integrate with AI coding tools such as Anthropic’s Claude Agent and OpenAI’s Codex.
Apple released Xcode 26.3 Release Candidate 1 around the same time as the RC versions of iOS 26.3, macOS 26.3, and its other platforms. However, when these operating systems were officially released on February 11, Xcode 26.3 was notably absent.
Apple released Xcode 26.3 Release Candidate 2 today, a sign that the company still feels it needs to be improved further before making the update officially available to developers.
It’s not immediately clear what the difference is between Xcode 26.3 RC 1 and RC 2, but the next release is notable, especially since Apple released the first beta version of Xcode 26.4 a few days ago.
Be that as it may, Xcode 26.3’s agent coding integration has received high praise from developers who have been using it since the first RC release. With RC 2 coming out today, it’s reasonable to expect that (barring any new last-minute issues) the final release could land sometime next week.
