I have to create an application with a minimum version in iOS 6.0 and Objective-C.
How can I create a new project in that version?
I've tried creating a normal project and switching to iOS 6 later, but it gives me a lot of errors.
Can an application in iOS 6 be seen correctly on a terminal with notch?
It is not possible to create an application with a minimum version in iOS 6.0.
AppStore won't accept your application. Most of old frameworks are deprecated and no longer supported by new iOS versions.
Your best option is to get versions of MACOS and XCode that supported IOS6.0
That would be OS X Yosemite and XCode 6 or 7.
You can install the old MACOS on a virtual machine or better download a Virtual Machine of older MACOS.
Be aware: Old versions of MACOS,XCode may not be secure and you will have to download from websites other than apple.

I was going through app review guidelines and one thing which I am unable to find the answers is
"Do I need to build my project with the latest available version of Xcode available on the Mac App Store or can I use the older version "
For example the current version of Xcode available on Mac App Store as of writing of these lines is Xcode 9.0, so do I need to build my project using Swift 4 and Xcode 9.0 or can I use older versions (say Swift 3.x and Xcode 8 or Xcode 7).
A similar question was asked in Feb 2012
Do I need the latest version of Xcode to submit apps to the app store?.
But it doesn't provide clear cut answer and the answer is more than 5 years old. And during that time the language for choice was objective -C whose versions were and are more stable than current lingua franca, Swift.
You can use older version of Xcodes (Xcode 8.x) to develop and upload
your project build on app store. There is no any such kind of
restriction by Apple, that you must use latest Xcode Tool to upload a
build on the store
I recommend and a as good advise,
You should use latest version of Xcode Tool to make your app, compatible with latest version of technology. You should see and implement, changes in technology. And one most important and major update in Xcode 9 is - support for iPhone-X device. To see your app interface is compatible with iPhone-X or not, you must use Xcode 9. There are so many other considerable updates in Xcode 9 (with iOS 11)
Here is list of updates with Xcode 9: Highlights of Xcode 9
It's not required to convert/change version of Swift programming language to provide a support of latest Tool.
Xcode 8.3 & Xcode 9, both supports Swift 3.2 version. So, if your current project is supporting, Swift 3.2 version, then you can easily work with Xcode 9.0
How to see current Swift version of your Xcode Project
Also, review this answer to see, how you can make your project compatible to Xcode 9 - Xcode 9 Swift Language Version (SWIFT_VERSION)
Here is nice answer from Apple:
Why You Should Use the Latest SDK
Building with the latest SDK gives your app all possible bug fixes and new behavior. For compatibility reasons, frameworks can't always expose improved behavior, unless apps are built with the latest SDK.
For example, when Retina enabled iPads were first introduced, only iPad apps built with the very latest iOS SDK could create Retina images by simply loading an image with an #2x suffix.
By building with the latest SDK, apps signal that they are ready for all API improvements and bug fixes.
Why is it important to download the new version of Xcode when there is a new iOS version released?
Suppose I installed iOS 11 on my mobile and I try to start developing an app with Xcode 8.3 (which does not support this new version of iOS), it will not work.
Sometimes, I also have to download new version of macOS.
For running development code on a device, Xcode has knowledge about the different versions of iOS that it can work with.
If you were trying to build and run on an iOS device with a new version of iOS, Xcode is set up to say it does not know about that version and will not work.
This allows Apple to update the way Xcode talks with iOS devices during development without newer iOS versions needing to remain backwards compatible.
I have developped my app on android but would like to do the dev for iOS.
I have an old mac that supports only 10.6.8 and xcode 3.2.6.
I can get access from time to time on a mac with 10.10.
my understanding is that the way to go now is swift.
will my xcode 3.2.6 support swift so that I could developp on my old mac and test on the newest 10.10.
what do you recommend I do? buying a new mac? :)
Many thanks!
Swift is only supported on xCode 6 like you can read here. And only for iOS 7 and higher.
So even methods are available for iOS 2, as long as the devices don't have installed iOS 7 or higher the swift code can't be executed and you would need to use objective-c instead.
I would like to run old application which has a support of iOS 5.0 and less. It has a deployment target 5.0. The thing is that:
I have upgraded system to Yosemite OS 10.10 and lowest Xcode version I have 5.0. Now when I look on base SDK and I see below picture.
As you see the least build SDK shown s iOS 7.0. No other lower version is there.
I heard or I read some where that you can also use lower version SDK here. By copying SDKs to some where or any other means. I would like to know a better approach here.
Edit:
I have a requirement of one application which was developed in Xcode 4.6 for iOS 5.0. So that just to check that application flow I need to download Xcode 4.6. Is it so? Can we don't include older SDKs in newer version of Xcode?
You should not attempt to build your application with an old version of Xcode. The only version of Xcode supported on Yosemite is Xcode 6.1, which only ships with the iOS 8 SDK. You should build for the latest SDK, and set the Deployment Target to iOS 5 if you want your code to run there (by degrading gracefully using NSClassFromString and respondsToSelector: checks)
I recently downloaded Xcode 4.1 for Lion with iOS SDK 4.3. Now, whenever I change my Deployment Target to anything older than 4.3, I get hundreds of errors when I try to build my project. This happens even if I'm trying to run it on the 4.3 iOS Simulator, so I don't even need to be actually running it on an older device, I just have to set the older Deployment Target.
Do I need to download a separate SDK in order to allow for older devices? If so, where could I find it?
Thanks for your help!
I tried copying the SDKs from Xcode 4, but it doesn't work.
Other answers suggest that it's not possible.
I'm now using a virtual machine with Snow Leopard to test on older devices. (Or real older devices, if you have one)
