Is it possible to install iOS 7 SDK on Xcode 6? - xcode

I have Xcode 6 installed but realise that I am only able to develop for iOS8. I am aware that this beta development kit is meant for the development of the iOS 8 beta release but I am in a position where I don't have the time yet to develop for it but wish to take advantage of some of Xcode's new features while I am developing for my current iOS 7 apps.
What can I do to get the iOS 7 SDK installed on xcode 6?

Seems like if you symlink the relevant SDK from a previous installation of Xcode to the Xcode 6 Beta directory, Xcode 6 will be able to use it. Assuming you still have Xcode 5.1.1 on your machine, try the following in terminal:
ln -s /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk /Applications/Xcode6-Beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk
This should link the iOS 7 SDK for iPhone (not sim), allowing you to select iOS 7 as the Base SDK in Xcode 6 Beta. If you want to do this for the simulator, replace iPhoneOS.platform with iPhoneSimulator.platform.
NOTE: Just because you have the iOS 7 SDK now doesn't mean it'll build. I'm personally having trouble with the fact that Xcode 6 Beta is using the Apple LLVM 6.0 compiler, which apparently isn't compatible with some of the stuff I'm trying to build.

Just posting so that someone might find it useful: I wanted to debug my app in iPhone running iOS 7.1, in XCode 6.0.1. The previous iOS version was not being listed in the settings page, to choose as base SDK/deployment target. (I'm using OS X 10.10 Yosemite). I installed both XCode 6.0.1 and Xcode 5.0.1 and copied
/Application/XCode501.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk
to
/Application/XCode601.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
Now I'm able to run iOS 7 apps from XCode 6.0.1.

I changed the deployment target just fine and installed on my iOS7 iPhone 4s all the same. You can do all your development this way and then use 5.1.1 to make your relevant builds. I wouldn't advice to build apps for production in this beta environment even if you could.

Just repeating Christian's comment (on Ziewvater's answer) so it's more prominent:
What's strange is the fact that after adding the symbolic link to my Xcode folder, I see my device twice with the exact name and with some infos (iOS build number, model, device identifier) in the target selector in the upper left corner of Xcode. Depending on which of the both entries I chose, my app works fine or not, no matter which BASE SDK I chose. ??! Anybody experiencing the same?
This is exactly my experience also! Me and my team were tearing our hair out trying to understand why some builds seemed to be working and others were not.
It looks like Apple must be ignoring the base SDK (or target... or something) when you pick the wrong device from the list.

in Xcode 6.1.1 (Window -> Preferences - Downloads) you can install iOS 7.1 simulator. unfortunately it doesn't install iOS 7.1 SKD. if you set deployment target to 7.1 all builds without any trouble. be worry!!!! it is up to you to check the compatibility with 7.1 (SDK is still 8.1). so or so, all runtime trouble should be seen in simulator. i use this approach to build for my iPhone 4 in swift, where iOS 7.1.2 is the last available. (simply don't use any classes available only for newer devices :-))

Using the device simulator for iOS 8 with Xcode 7

I thinking about port my App to Swift 2 and Xcode 7. But the device simulator only targets iOS 9 and I see no way to download iOS 8.
I have parallel Xcode 6.3 installed. Is there any way to test and debug my app under iOS 8 with the device simulator?
You can download older versions of iOS via Xcode.
Open
Xcode -> Preferences -> Components -> Select
all the iOS versions you want ( iOS 8.4 )
Once downloaded, you can get to it in the
Simulator -> Hardware -> Device
I am using Version 7.3.1 (7D1014)
Xcode release note says below thing,
Simulator
Xcode 7.0 beta does not support iOS 8.4 and earlier simulator
runtimes. (20699475)
Refer this link for more info.
It can be used. You just need to find the file for the 8.x sdk that you want to test on in Xcode 6.x and copy it over to the corresponding Xcode 7 beta folder. You can find the file in this path.
Path: /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Xcode will suggest that you fix an error or two, but it should work. Note that when I did it there was still an error and some warnings, and I clicked run anyways and it worked regardless
You may need to click "other" and add "iphoneos8.x" (x is your version number)and if you have it added to the correct location it will work

Is it possible to install iOS6 SDK on Xcode 6-beta?

I noticed that there are no preview or simulator for iOS6 in Xcode 6-beta, so I was wondering is there any way that I could add it manually ?
No.
Apple only support iOS7 and iOS8, and they're strict with that. As a result, only iOS7/8 simulators are available in Xcode 6.
If you want to run on an older simulator, you need to develop on an older version of XCode.
Not possible. But: you can still test on a iOS 6 device from Xcode 6. I keep an old iPhone 4 for this (look at eBay).
EDIT: there is another way - install Xcode 5 on a virtual machine (e.g. VMWare Fusion) running Mavericks.
iOS6 simulator is available in Xcode5
No, the earliest SDK you can get for Xcode 6 is 7.1. By default, the iOS 7 simulator is not installed but you can install it by going to preferences, then to downloads and installing it from there.
To run iOS 6 applications, try googling around for an earlier Xcode version (late versions of 4) and these should have the simulator!
Hope that helps!

Xamarin.iOS Target iOS 6 SDK

We have upgraded to XCode 5 and Xamarin.iOS 7.x, but have one app we are not quite ready to support iOS 7 for yet.
Is there a way to target the iOS 6.0 SDK, and compile the app so that it has the old iOS 6 keyboard, etc.?
We tried changing the settings in iOS Build->SDK Version, and we can change it when targeting the simulator, but the option doesn't exist for AhHoc or AppStore builds.
Any ideas?
Xcode ships with several simulator SDK but only one device SDK. So you need to install an older version of Xcode. E.g. installing Xcode 4.6 will give you the 6.1 SDK).
Both versions can coexists side-by-side if you rename the existing one before installing the 2nd.
Be sure to have XS points to the Xcode you want to use (it's not a project specific setting).

Does xcode4.5 support ios4.3 simulator or prior?

I have upgrade to xcode4.5 from 4.4, but i can't find ios simulator 4 or prior within it. I open Xcode menu, preference, downloads, i can see simulator5 and 5.1 only. I am not sure whether xcode4.5 support ios simulator 4 and debugging with ios4.3 and prior.i know almost iphone and ipad people upgrade their ios to 5 already. but we have some project runs in ios 4.3.does someone know how to install simulator 4 in xcode 4.5?
thanks in advance.
Looks like it has been removed from xcode 4.5 on Mountain Lion:
xcode 4.5 runs ios 4.0 simulator (NOT)
According to Apple you can still set the deployment target for 4.3 though:
https://discussions.apple.com/docs/DOC-3461
The minimum supported deployment target with Xcode 4.5 or later is iOS 4.3.

how to fix old xcode installations on mac

I had xcode 3.2.something. and iwth ios sdks 3.0-3.1-....4.1 and 2 iphone simulator sdks.
Now i installed xcode 4.0 with ios sdk 4.3 something like that.
Now all my previous applications cannot be launched nor on device nor on simulator because there's not a single old sdk available.
so next i reinserted the original cds containing macosx and xcode and reinstalled the first xcode i used, but now there's not one ios sdk available at all.
i've been surfing the net for hours now, andi have a couple of questions:
1)have i had to uninstall the xcode 3.2.x before installing xcode 4?
2)how to uninstall applications on mac??? just to make sure that the answer i've found is the correct one.
3)how can erase the traces of all previous xcodes and their sdks in order to install the original one, now that i learned how to install different xcode versions side by side.
4) now what do you think i should to recover? do i have to back up everything and reinstall mac from the beginning?
thank you
So, your questions:
1. Have I got to uninstall XCode 3.2 before installing XCode 4? - No, you don't, but the XCode installer will overwrite your old copy by default. When installing the newer version of XCode and the iOS SDK you must specify a different install directory (eg, create a new folder in the root of your drive called 'Developer 4' for XCode 4.
2. How can I uninstall XCode? - Normally on a mac you would just drag your application to the trash, but it's a little more complicated with XCode. Refer to the instructions at this link: http://pushkararora.com/how-to/how-to-uninstall-xcode-completely/
3. How can I erase all traces of all previous XCodes? - see the answer above for question 2 :)
You can obtain old versions of the SDK from various unofficial online sources if you need to roll back to iOS 3 SDKs. However, it may not be all that much work to move your apps over to the 4.x SDKs.
ok it turned out that at the beginning i was using xcode 3.2.4 with ios sdk 4.1
The xcode that comes with mac osx only targets mac sdk. No iphone support
So i got xcode 3.2.4 setup from a backup (you can find it online) and installed and this should work
And now i have 3.2.5 using sdk 4.2 and targetting all till 3.0
and also xcode 4.0.2
