Download iPaSim – Open Source iOS Simulator for Windows

iPaSim is an open-source iOS simulator for Windows that allows developers to run and test iOS applications on a Windows PC without needing a Mac or physical Apple device. Built using the QEMU emulator and Wine compatibility layer, iPaSim translates iOS system calls into Windows-compatible equivalents, enabling basic iOS app execution in a simulated environment.

The project is primarily aimed at iOS developers on Windows who want to perform initial testing and debugging of their apps without switching to macOS. It provides a simulated iPhone environment where apps compiled for iOS can be loaded and run, making it a useful tool for cross-platform development workflows.

Note that iPaSim is an experimental project and does not support all iOS APIs or hardware features. It is best suited for testing logic-heavy applications and basic UI interactions rather than apps that rely heavily on iOS-specific hardware like cameras, GPS, or Bluetooth.

Key Features

• Run compiled iOS applications on Windows without a Mac or physical Apple device.
• Built on QEMU emulation and Wine for iOS-to-Windows system call translation.
• Simulates an iPhone environment for basic app logic testing and UI previewing.
• Supports apps compiled with standard iOS SDKs for ARM and x86 targets.
• Open source project — free to use, study, and contribute to on GitHub.
• Useful for cross-platform developers who need quick iOS environment access on Windows.
• Lightweight setup compared to running a full macOS virtual machine.
