Assuming you are targeting multiple platforms – most likely iOS and Android and some Windows too – you would need a Mac to compile your cross-platform solution for iOS.
As it appears, when using the Cordova framework for your project you can build iOS and Android from your Mac, but not target Windows from it. From a Windows machine, you can target Windows and Android but not iOS (since compiling Mac executable code may only be done on a Mac).
That leaves you with at least having to use some sort of Virtual Machine (VM) solution if you don’t want to reboot to reach the other side of your Mac (one partition running Windows, the other one Mac OS X).
In this post I discuss some required stuff for creating cross-platform mobile apps for the top 3 mobile platforms (iOS, Android and Windows) and what Virtual Machine software will be the best setup to enable you to build for them.
Please note (as mentioned in the comments) that Apple’s EULA prohibits you to use a Virtualised Mac OS box on Non-Apple metal. In this post i’m talking about running a Mac with VM to extend- and improve the platform development t0wards other platforms (Android and Windows).
More after the break.
The Hyper-V factor & Windows apps
If you develop for multiple platforms and Windows is one of them you’re bound to encounter the need for a Hyper-V based Emulator when testing your app for Windows Phone 8. Even the latest Windows 10 emulator – still a pre-release – is based on Microsoft’s Hyper-V VM technology.
And that is a crucial factor when you want to pick the right VM software for your mobile development brick. Since Virtualbox is a very nice free virtualization solution but it doesn’t support Hyper-V yet. Your VM images need to be able to run Hyper-V (called nested virtualization) and Virtualbox just isn’t up for that job.
Fast emulation for Android
A fast running emulator for your Android platform build to test if Android (especially when not using Crosswalk) doesn’t screw up the rendering on different OS versions is a must. If your emulator slows down your code-build-test cycle frustration will rise and the possibility to introduce failures rises along.
One of the things to keep your Android emulator running fast as lightning is NOT using Androids default emulator, but using an emulator solution like Genymotion or Xamarin Android Player which includes fast emulator installment and running your app on different configurations fast & furious. And let it just be fate that these solutions are based on the Virtualbox VM software when it comes to running them on a Mac OS X machine.
Please DO NOTE that this is the truth for both native and hybrid (Cordova based) mobile app solutions
Let’s play nice
Having your Windows VM integrating nicely with your Mac OS side of the force is another important criterium to get your developer box setup for completeness sake and get going for iOS, Android AND Windows apps.
This means that you need to be able to switch the VM fast, start and stop it fast and it should let you pick files from both the VM and Mac OS like it’s one and the same. VM software like Parallels or VMWare Fusion have modes that blend in the Virtual Windows environment to act as if the running software is running on your Mac OS. This has some advantages like:
- all programs run on the same desktop, your Mac OS’s
- copy-paste and other clipboard like stuff works with your Mac shortcuts
- file access is easier either by shared locations (VMWare) on your drive or by entirely linking and making the hard disks accessible (like Parallels)
I got to say though – and no I’m not affiliated in any way – that Parallels has unbeatable integration and that both their hard disk access and integration with the Mac OS is working mighty fine. Both VMWare Fusion and Parallels can run Hyper-V simulators although it’s more of a hassle with VMware and just works out-of-the-box with Parallels.
Wrapping up a.k.a. the verdict
You want to be able to service all customers and get your top 3 mobile platforms (iOS, Android and a sniff of Windows) going for you? Better be prepared to get the best setup:
- Your Mac OS X computer (of course)
- VirtualBox in combination with one of the following Android emulators:
- Xamarin Android Player
- Parallels (my preferred one for the best clipboard and hard disk integration and seamless app combining)
And there you have it. Download, install and build one to rule them all!
