Can we use Xcode without an iMac?

Probably somehow. But the point is compiling for that hardware, so if you don't have Apple's hw, it's kind of pointless. Been there :/

@KeyWeeUsr Well I have an iPad mini 3 and 4

When I was making apps for iPhone on a windows PC I made a virtual machine in VMware and booted it up. It requires a bit of tinkering to make the VM and also to make it at a useable speed.

@joelparavara I believe what @KeyWeeUsr is saying is that, you need an iMac or MacBook to write and compile code in that OS environment to run on your iPad and other iOS devices. You can't write and compile code of the two gadgets you're talking about.

@suprano Exactly. Ok, maybe with Hackintosh or similar there is a way how to install a complete environment, but what's the point if you compile for e.g. i386 if the target is arm/powerpc/...? However, if they have "anything to arm" compiler, then you could compile the same way people compile to android's archs.

I wonder if you can install xcode on ipads as you probably could do something similar with android sdk/ndk's source and compile directly on the targeting device.
