installing multiple versions of Xcode

[cusingerBUSCw5N]

I have just purchased an MacBook to convert my app to IOS - so I am truly a newbie. I was able to download and install Xcode 4.5.1 (although I really don't know how it installed, since there wasn't the same interface that I am used to on a PC).

After failing to create a standalone, I looked in the forum and found that I actually need to install multiple versions of Xcode. I renamed the original folder (which was put in the Apps folder)...and downloaded Xcode 4.4.1 It shows as a download, but there is no option to install it. So it's sitting there - and I don't know what to do. I tried downloading the command line tools for xcode os x lion....but that is a .dmg file also and comes up "The following disk images couldn't be opened - reason - not recognized."

So...can I develop this app with only Xcode 4.5.1.... and if not, how do I actually install downloaded prior versions?

Thank you.

Hi,

"The following disk images couldn't be opened - reason - not recognized."

means that something went wrong with your download and the downloaded file is corrupted.
Try re-download it.

but there is no option to install it

On mac side, there are very few apps that need to be installed. In most cases, you just drag and drop the *.app file to your applications folder.
That's it. Think the mac apps as portable apps in windows. Everything it needs, it contains within itself.
A little more detail about this issue?
Well, right-click on your *.app file, and click Show Package Contents.
See? It's actually a folder, just wrapped up so that double-clicking starts necessary services or threads and finally runs the app.

I don't do this. And I absolutely don't know why people need to do this.
I have one xCode version {Version 4.5.2 (4G2008a)} and one LiveCode version {Build 1497 Version 5.5.3},
everything works just fine.

I'm just copying iPhoneOS5.1.sdk folder to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs folder,
and iPhoneSimulator5.1.sdk folder to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs folder
whenever I update my xCode app, because it only comes with iPhone6 SDK and delete all other stuff.
And in the Standalone Application Settings... of LiveCode under File menu,
I choose Build For iOS 5.1 or later Armv7.
It works like a charm for months now.

Hope it helps...


Best,
