System Requirements for iOS

Xcode

Xcode is required for building, running, and testing iOS applications in a controlled macOS environment. It provides the complete Apple toolchain, including compilers, SDKs, simulators, and command-line utilities necessary for executing automated and manual iOS test workflows. For enterprise teams, Xcode ensures compatibility with Apple’s platform requirements, supports secure code signing, and enables consistent simulator-based testing across development, QA, and CI environments. Standardizing Xcode versions and macOS configurations is critical to maintaining reproducibility, stability, and compliance across large-scale test infrastructure.

Xcode System Requirements:

Component	Requirement	Description
Operating System	macOS 12 or later	Required by Apple for supported Xcode versions
Processor	Apple Silicon or Intel (64-bit)	Apple Silicon recommended for emulator performance
Memory	Minimum 8 GB RAM (16 GB recommended)	Required for smooth simulator usage
Storage	40–50 GB free space	Xcode, iOS SDKs, and simulators consume significant disk space
Network	Stable internet connection	Required for Xcode downloads, SDK updates, and provisioning
