Xcode, on tap.

Every Cobalt session runs on its own Apple Mac mini with the M4 chip — a 10-core CPU, 10-core GPU, 16 GB of unified memory and a 256 GB SSD — with Xcode already installed.

Specifications

The silicon under the hood

One configuration for every session: Apple's M4 Mac mini.

CPU10 cores

Apple M4 with 4 performance and 6 efficiency cores — Swift compiles across all of them.

GPU10 cores

Drives Metal, the SwiftUI canvas and Simulator rendering on the Mac itself.

Unified memory16 GB

Shared by the CPU and GPU, so Xcode, a Simulator and Instruments work from one pool.

SSD storage256 GB

Internal NVMe for your repositories, DerivedData and archives.

Your machine

A whole Mac, not a slice of one

Nobody else uses the machine while it is yours, so Xcode behaves exactly as it does on a Mac on your desk.

  • The whole machine is yours for the session — a physical Mac, not a virtual one
  • Xcode is installed, with the iOS Simulator and Instruments that come with it
  • Full administrator access: add Homebrew, Fastlane, CocoaPods or anything else you use
  • Archive in Xcode and upload to TestFlight with your own App Store Connect account
  • Runs macOS Tahoe, Apple's current release
