Xcode Installation Failure with GUI App

Xcodes App: Xcode Installation Failure Despite Apple Account Login

Environment

• Operating System: macOS Sequoia 15.3.2
• Machine: M4 Pro
• Xcode Target Version: 16.2
• Installation Method: Using Xcodes app (installed via brew install --cask xcodes)

Problem Description

After installing the Xcodes app via Homebrew (brew install --cask xcodes), I am unable to install Xcode through the app, even though I am correctly logged into my Apple account.

Steps to Reproduce

1. Install Xcodes app using brew install --cask xcodes
2. Open Xcodes app
3. Attempt to download and install Xcode version 16.2
4. Observe installation failure

Expected Behavior

Xcodes app should successfully download and install the selected Xcode version.

Actual Behavior

Xcode installation fails within the Xcodes app, despite being logged into the Apple account.

Additional Context

• Direct Xcode installation through App Store works correctly
• Apple account login is confirmed and functioning
• Problem persists across different Xcode versions

Possible Investigations

• Are there known compatibility issues with Xcodes app on the latest macOS?
• Could there be permission or authentication problems specific to the Xcodes app?

Requested Action

Investigate the root cause of Xcode installation failure within the Xcodes app on macOS Sequoia.

Start by reproducing the Xcode 16.2 installation failure in the Xcodes GUI app on macOS Sequoia 15.3.2 using the listed Homebrew installation method. Compare the failing app-based installation with the working App Store installation and identify the relevant authentication, permission, or compatibility cause; done means the selected Xcode version installs successfully through Xcodes.
