Previously, a colleague of mine encountered a situation where the company-issued computer was Windows, but the project required participation in iOS development. A troublesome aspect of iOS development is the environment lock-in: macOS + Xcode is a hard requirement, and Windows cannot directly compile and sign iOS apps. Later, after trying several different approaches, we found that although each has limitations, each also has its own applicable scenarios.
Install macOS in a Virtual Machine
The most straightforward approach is to run macOS on Windows through a virtual machine. Install a macOS image in VMware Workstation or VirtualBox, then install Xcode and the iOS SDK inside the virtual machine. This effectively gives you a complete Mac development environment running on Windows. The advantage is that you can run the full Xcode, including Instruments and the debugger. The disadvantages include high hardware requirements—at least 16 GB of RAM, CPU with virtualization support—and significant disk space taken up. Running macOS on non-Apple hardware also has licensing restrictions. In terms of compilation speed, Xcode in a virtual machine is considerably slower than on a real Mac, and for large projects, every clean build takes a long time.
Compiling on a Remote Mac
Another approach is to write code on a local Windows machine and remotely connect to a Mac for compilation. On Windows, you use VS Code or any editor for development, then SSH into the remote Mac and use the xcodebuild command to package. This approach gives you freedom in your coding environment—you can use your preferred editor, plugins, and fonts. The remote Mac can be a shared Mac mini or a Mac server.
The main drawback is that compilation and debugging are split between two separate environments. You write code on Windows, push it to the remote for compilation, and when errors occur, you switch back to local to fix them—each iteration cycle is much longer than local development. Certificates and provisioning profiles must also be managed on the remote Mac, and compilation can easily time out when the network is unstable. If you only occasionally participate in iOS development, it’s acceptable; but when it becomes frequent, efficiency suffers.
Using KXApp on Windows
KXApp takes a different approach than the two previous options. It is built on VS Code, and the editor itself runs natively on Windows. The difference is that it includes an iOS compilation toolchain, allowing you to compile and sign apps without installing Xcode on the system. From creating Swift, Objective-C, or Flutter projects to building IPA files, everything can be done on Windows.
For real-device debugging, iOS devices connect to the Windows PC via USB, and KXApp can directly recognize the device. Click the one-click build and install button, and the tool automatically handles signing and deployment—no need to operate a remote Mac or configure virtual machine network bridging. If your project uses Flutter, KXApp directly supports Dart compilation to iOS, saving the step of configuring the Xcode toolchain in the Flutter environment.
There is still no perfect solution for iOS development on Windows; each approach has its own trade-offs and focuses. The virtual machine approach is feature-complete but resource-intensive and consumes disk space. Remote compilation is flexible but switching between multiple environments hampers efficiency. KXApp covers the main phases of iOS development—coding, real-device debugging, and packaging—making it suitable for fast development, real-device testing, and daily verification in a Windows environment, reducing dependence on Mac hardware.
