I work on Mac 10.6 because I don't want to lose spaces to Lion. It's an extremely efficient part of my workflow. And I program for the iPad and need to write for iOS 5.1 and the new retina display, but for some reason apple has made the new Xcode only available for Mac 10.7 or later.
How can I either install the new Xcode, find a workable Xcode, or somehow install iOS 5.1 support into my current Xcode? (4.0.1)
You can not do that without cheat with Apple, you need to stay up to date !
It is not possible, you have to upgrade. Xcode 4.3 is coded with innovations that will only work on OS X Lion.
The cap was Xcode 4.2 that ran on SL. You will have to upgrade or continue only developing for older, legacy iOS versions (not a good option).

I'm on El Capitan in XCode 7.3.1 and Swift 2 trying to make my mac application work on Yosemite (it just doesn't open at all with no crash logs).
I have 10.10 set as the deployment target, but that didn't change anything.
I downloaded Xcode 6.4 on another machine and loaded the project and it's complaining a ton about all of my swift code not being a thing.
I'm assuming (hoping) I don't have to figure out how to write this in an old version of Swift in order to make it work on Yosemite.
How do I know which features of the new SDK need to be made backwards compatible?
Could the very first generation of the Mac Mini handle app development for the iPhone? My friend said he'd give me his for free to use XCode, but I want to make sure that it could run it before I take it.
Short answer: For current iOS versions? No. For any iPhone? Yes.
The latest OS X supported on that hardware (officially, don't know about hacks) is 10.6 and the latest Xcode you can get for that is 4.2 (if you have a paid account, it seems). Xcode 4.2 would support iOS 5.0, so if that's enough, then it can be used for development for iPhone. But I assume that's not what you're after, since a lot has changed since iOS 5.0.
No. If you are trying to develop against IOS8. You need OSX 10.9.4(Mavericks) to run XCode 6.1.
Minimum OS X and xcode requirements for ios 8.1 development
I can't install Xcode 4. I have some files that I need to open in Xcode 4. However, when I try to install it, it says "Xcode Install Assistant cannot be installed on this disk. The version of OS X is too new." How can I make it think I'm on Lion or Mountain Lion?
Here is a picture:
Download it in the App Store - it's the newest version and looks like the disc you have doesn't support Mavericks.
I feel tired of these preposterous answers. I think that if you want to stick to an older version of something, you should be able to. Also, I don't think software like XCode 4 are that old anyway.
But, to the point: I think XCode 4.6.3 is compatible with Mavericks. I am not sure about previous 4.6.X, but I think none of them work.
Any versions prior would require a previous operating system. I think you could try using pacifist to install the version you want, but I haven't found any guides.
If your problem is with project compatibility, in XCode 5 there is an option to save the project in a way it is compatible with XCode 4.6, and I suppose 4.6 offers a similar option to save in a version prior. Of course, you may need to adapt the code of the projects accordingly. Usually I try to stick with the Snow-Leopard-compatible code, because it compiles fine in all XCode 4.X and 5.X versions.
You can download any of these from the developer website.
I would try partitioning the disk and installing an older Mac OS X. I work with Snow Leopard and Mavericks in the same Mac. I usually do interface tasks in SL and the rest on Mavericks. The other advantage is that I have both XCode 4.2 and 3.2.6 in the same machine, so I can manage some backwards compatibility. =D
I'm on Mountain Lion at the moment but the battery life is terrible and I'm thinking of downgrading back to Snow Leopard. The only thing is, now that we have to submit our apps for the 4-inch screen of the iPhone 5, will the last Xcode build supported on SL (4.2 I believe?) be able to build these apps? Or am I completely stuck on ML?
The latest Xcode with which you can use the 4-inch iPhone simulator runs only on Mountain Lion.
However, if you don't mind not using Xcode, you can extract the essential parts of the toolchain (the compiler and the headers + libraries) and use the clang compiler from the command line - it should run just fine even on SnowLeopard and compile your apps.
You are stucked to Mountain Lion! :)
Xcode 4.2 doesn't have support for ios6, neither iphone 5 nor ipad mini
I have just bought a macbook air 11" with Lion 10.7. I installed xcode 3.2.5 on it. But its not working. Xcode is installed, consuming much space but I cannot see it in applications. Somewhere I heard that xcode 3 will not work on Lion 10.7, only xcode 4 is compatible on this os. Is it really true? I tried removing xcode 3 but efforts go worthless. What should I do to uninstall it?
For Xcode, you want to use scripts provided with Xcode to remove it completely. Open a terminal window and invoke /Developer/Library/uninstall-devtools. Alternatively, you can just drag the Developer folder to the trash, but I don't think that removes everything that gets installed by the installer.
And no, Xcode3.2 won't work (entirely right) under Lion. You need Xcode4, v4.2 being the most recent with the iOS5 SDK. And if you want to submit anything to Apple, you'll need 4.2 (i.e. the latest released tools) anyway, at this point.
I would use this utility. It's always worked better than the traditional way to "unistall" applications form OSX

The reviews have always been good for this app.
