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?

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 needing to compile a C++/C/Objective-C project for 10.5 (ppc, intel)+ however Xcode 4+ (using 4.6) drops support for 10.6 and i believe Xcode 4 completely dropped support for 10.4/ppc. I have read existing StackOverflow and other posts about installing Xcode 3.2.6 on Mountain Lion but i don't want to do this if it's unconfirmed/will break my system..
I've tried virtualising Snow Leopard in a VMware Fusion 5 Pro VM but it doesn't allow me to as it is not a server version.
Besides buying a Snow Leopard Server DVD, how else can i compile my project for 10.4+ (ppc,intel)? I am currently running OS X Mountain Lion 10.8.3. Setting the deployment target does not work in my Xcode version, doesn't compile. I've also considered virtualising Lion, however i do not have a backup copy of (my purchased via app store) install dmg/app and i can't seem to find the download in the App Store.
Can anyone suggest what i should do or am i basically left with one option.. Dual boot Snow Leopard?.
Thanks!
I am working in a mac application with snowleopard.This application is created with leopard os,but this not support in lion due to some external application.So we converted this to snow leopard and work fine .Now the client need to convert this application to leopard version ,for that i am using the xcode 4.2 and lion os and convert the bsec SDK to Mac osx 10.5 and Architecture to 32_bit intel ,but we getting an error "The run destination My Mac 64-bit is not valid for Running the scheme 'AppName'."
How can avoid this error ?
I want to test this application with 10.5 os, but we have only the 10.6 & 10.7 osx,
1)where we get the leopard osx ?
2)Has the Apple issue leopard osx now?
3)Is any problem for instal the leopard os to new MAC system(iMac,Macmini,Macbook)?
I had the same problem a while back, but I'm recalling the solution from memory, as my company dropped 10.5 support meanwhile. The details might be a little bit off, but it should get you going in the right direction:
Grab the latest version of Xcode 3 from the Apple Website
Install it on a Mac. (Make sure you removed the Developer directory if this Mac had another version of Xcode already installed).
Under /Developer, locate the 10.5.sdk directory. Move this directory to a save place (outside of /Developer).
Install Xcode 4.2.
Look where Xcode 4.2 installed its sdk's. Put your previously saved 10.5.sdk directory next to it.
Restart Xcode. There should be 10.5 SDK option in the SDK drop down menu now.
I installed XCode 4.3 from App Store. When i run the application the xcode version is showing 4.1.
Present my mac version is Mac OS X Lion 10.7.3. Can any tell me the process how to load xcode 4.3.
Thanks in advance.
Just install it from LaunchPad.
You may have to explicitly go to the Mac Store and get this update as though it were a new download; it used to come through Apple->Software Update in the past (and I think in the future it will be a Mac Store update that you get just like any other Mac Store update), but this particular transition (4.2->4.3) is a bit more work.
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).
