Hi there! As a seasoned mobile app testing expert with over 10 years of experience testing on thousands of real devices, I know how challenging yet crucial it is to ensure flawless iOS app performance across platforms.
Many developers and testers often ask me:
"What is the best way to test iOS apps on the Windows machines we already own?"
Great question! In this detailed guide, I will walk you through different methods to emulate iOS environments on Windows along with an analysis of the pros and cons of each approach. My goal is to equip you with a clear methodology tailored to your use case so you can start testing iOS apps on Windows right away.
By the end, you’ll have answers to all your questions related to emulating iOS on Windows:
- What are the benefits of emulating rather than using physical devices?
- What tools are available and how exactly do they work?
- What criteria should you consider when selecting an emulation solution?
- Which method aligns best with your needs – occasional use, CI/CD, debugging?
Let’s get started!
Why Emulate iOS Environments for Testing?
Before looking at the HOW, it‘s important to understand the WHY. Here are 5 compelling reasons why you should emulate rather than always rely on physical iOS devices for testing:
1. Significant Cost Savings
Purchasing even a handful of iPhones/iPads for test devices can get extremely expensive:
- Latest iPhone 14 Pro – $1000+
- iPad Air with cellular data – $750+
- Buying 5+ devices – $5000+
Emulators provide similar functionality at a fraction of the cost.
2. Flexible Iteration of Tests
Rebuilding an app binary and reinstalling on physical devices after every code change slows down the rapid iteration needed for effective testing.
Emulators allow seamlessly relaunching multiple simulator instances without tedious reinstalls.
3. Wider Coverage of Test Scenarios
Configuring physical devices to represent different iOS versions or device types (iPhone vs iPad) can be quite complex.
Emulators make it easy to simulate testing across 20+ device types running different iOS versions with a click.
4. Debugging Ability
Certain emulators like BrowserStack allow debugging iOS apps directly on Windows using Chrome DevTools or Visual Studio, unmatched by physical devices.
5. CI/CD Integration
Automated testing through continuous integration pipelines is easier to orchestrate using swiftly provisionable emulators rather than flaky physical devices.
Clearly, emulators solve many limitations of physical devices for testing needs.
Now let‘s explore popular methods to emulate iOS environments on Windows specifically.
Methods to Emulate iOS Environments on Windows

2. Local iOS Simulators
You can leverage built-in iOS simulators in native IDEs (Integrated Developer Environments) or use standalone third-party emulators that run locally on the Windows machine:
Xcode:
- The official IDE for iOS app development by Apple with an in-built iOS Simulator.
- Allows testing apps across iPhones, iPads, Apple Watches etc.
- Since Xcode runs only on macOS, you‘ll need to access it using a VM.
Android Studio:
- Primarily Android focused IDE providing full emulator support.
- Can be configured to emulate iOS devices and runtime too.
- Leverages native Hypervisor framework for better performance.
Remix OS Player:
- Advanced Android emulator for Windows with ability to install Xcode and iOS SDKs.
