Installing iOS SDK and Xcode on Windows 7

Apple has been adamantly refusing to create an iPhone SDK support for Windows-based machines. Luckily, there is a work around to be able to fully run the iOS SDK and Xcode support for most all PC's.

The following steps involve installing a virtual machine on your PC, updating the virtual machine to 10.6.5, then running the machine and downloading and installing the iOS SDK and Xcode on to the virtual machine.

There are other ways to install OS X on your machine but they involve creating a new partition and installing the Operating System directly to your hard drive. Those ways are much harder and have more confusing steps that could potentially damage your computer. This method is easier and safer to use.

The process will take 3-4 hours, but most of the time is consumed by large downloads. There's no software to buy or developer fees to pay.

Instructions

1. Follow the steps here to download and install a virtualized version of OS X on your PC.

2. Make sure you have updated to the latest version of OS X, Xcode won't work with older versions of OS X.

3. Once you've updated, in the virtual machine, go to the the Apple Developer page. Create a new account. Then go to the downloads page.

4. Scroll down to the downloads. Click on Xcode and iOS SDK. The download will likely take around 1 hour but depending on your connection, it could take longer.



5. Once the download is finished, double-click on the .dmg file, then click on Xcode and iPhone SDK.


6. Follow the on-screen directions then wait for the installation to finish.


7. Once it's done, you will NOT find the iPhone SDK in your dock. You will need to click on your hard drive (the icon at the top right of your screen). Then Click on Developer, then on Applications.



8. You will now see an icon for Xcode, click it and you can start coding applications.


If the icons don't show up, you may not have enough virtual hard drive space to fit the program. Make sure you have at least 10 GB of free memory in the virtual machine. Restarting your machine may be another way to make the icon appear.

Now you can start coding an app for your personal use. You will be able to test your app on the iPhone simulator in Xcode but you will not be able to add the app to your own device. To add an app that you've created to your device, see the two options below.

Option 1: If you want to submit your app to the App Store, you will need to pay Apple $100 for an official Developers Certificate. This will allow you to sell your app to a very large audience but Apple does place large restrictions on its approval of submissions.

Option 2: If you don't want to pay the $100, you can develop your application for Cydia (similar to the App Store). This option will also allow you to place your app on to your iPhone, not just only in the Xcode simulator.

Cydia is the unofficial App Store for users who have jailbroken and want to sell/share their apps. There are almost no restrictions as to what kind of apps that can be added to Cydia.

To develop for Cydia, you will need to have your device jailbroken (How do I jailbreak?) and before you start developing your app, you will need to follow these steps to create an alternate Certificate.

How to Virtualize OS X on Windows 7

With newer computers, it is now possible to run two Operating Systems at once, one running inside of another. This guide will describe the process of running Mac OS X 10.6.2 on a machine already running Windows 7 or Vista. This process will likely work on Windows XP but has not been tested.

This will enable you to run all programs for the Mac Operating System on your PC.

Requirements

A laptop or desktop computer that supports virtualization (most newer computers do).
At least 1 GB of RAM (the more, the better).
VMware Player (virtualization software, you will need to create a free account).
Snow Leopard 10.6.2 (Operating System).
Snowy_VM.zip (extra files for installation).

Instructions

Before you start, make sure that you have enabled Virtualization in the BIOS of your computer. This is usually disabled by default by computer manufacturers.

1. Unzip Snowy_VM and navigate to the following file: Snowy_VM\Snowy_VM\Mac OS X Server 10.6 (experimental).vmwarevm\Mac OS X Server 10.6 (experimental).vmx.

Double click this file, it will open VMware Player.

2. You should see a black screen now. On the blue VMware bar, press Virtual Machine > Virtual Machine Settings > CD/DVD > Settings.

3. On the left, click Use ISO image file, then click Browse.

4. Now select the Snow Leopard 10.6.2 iso file downloaded from the torrent above. Press OK to close the box and return to the black screen.

 
5.  On the blue VMware bar, press Virtual Machine > Send Ctrl + Alt + Del. The machine will now boot up with the iso file. Once the text appears, press F8 on your keyboard.

This is the screen where you can enter in boot flags. Depending on your computer, you may have a different flag from another computer. Many computers have worked without boot flag, so try that first (just press Enter).

A gray screen will appear. In a few moments, a language box will appear. If it does, go down to step 6.

If this screen doesn't appear for 10 minutes you will need to enter a boot flag. Go to the blue VMware bar, press Virtual Machine > Power > Reset. Press F8 at the same screen again. Now enter -x -v busratio=20 cpus=1 arch=i386 -x32. If you get to the language screen, move to step 6.

If you still don't get the language screen, press Virtual Machine > Power > Reset. Press F8 at the same screen again. Now enter -v at the boot screen. This will allow you to figure out exactly where the problem is computer is freezing. You can then Google your error.

6. Follow the on-screen steps until you reach Install Summary.

7. Here, click on Customize.

8. Select Mac OS_X_10.6.2. Under Kernels, select Legacy_kernel_10.2.0. Under Graphic_Drivers, select GraphicEnabler. Click Done.Click Install. This process should take around 10-15 minutes.

9. Once it's done, the count down from Step 5 will appear, press F8. Then on the blue VMware bar, press Virtual Machine > Virtual Machine Settings > CD/DVD > Settings.

10. Now go to Snowy_VM\Snowy_VM\darwin_snow.iso.

11. On the blue VMware bar, press Virtual Machine > Send Ctrl + Alt + Del.

12. Now wait until OS X 10.6.2 boots up! Just follow the simple setup instructions to create your user account and you'll be on OS X Snow Leopard. If the boot time is extremely long, go to the blue VMware bar, press Virtual Machine > Power > Power off. Then double click the name of your machine in the left column to start it up again.

13. When shutting down the machine, use the X in the top right corner or use the blue VMware bar, press Virtual Machine > Power > Power off.

14. Now to update to the latest OS X version, follow steps 2-4 on this guide:

15. To enable an internet connection on the OS X machine, see this guide:
