Releasing iOS apps built with an older SDK version - ios

My App Store question doesn’t seem to be answered clearly in the official guidelines document so here you go.
My app is developed for iOS8, its deployment target is 8.1. We would like to have it reviewed around next week.
Now there is the iOS9 version coming up. Will I be able to upload our binary to itunesconnect without any change? Will we have to compile with a newer SDK to pass the review process? Will I need to install a new version of Xcode do be able to upload a binary?
We would like to submit the app as is, without touching anything. (same situation as if it had been release 3 weeks ago) Is that possible? Thanks

Will I be able to upload our binary to itunesconnect without any change?
Yes. Apple will not require that you build your app against the latest SDK. Will you have problems with folks running iOS 9? Maybe?
Will we have to compile with a newer SDK to pass the review process?
No.
Will I need to install a new version of Xcode do be able to upload a binary?
No.

Yes.
Also, here's a great post about the difference between the Base SDK and the Deployment Target settings: What's the meaning of Base SDK, iOS deployment target, Target, and Project in xcode

All iOS apps submitted to the App Store must be built with the iOS 15 SDK or later, but our iOS SDK is already of version 15.2

I have found similar questions in this and this articles, but neither can solve my problem.
The message given by Apple Store Connect was also "ITMS-90725: SDK Version Issue - This app was built with the iOS 14.4 SDK. All iOS apps submitted to the App Store must be built with the iOS 15 SDK or later, included in Xcode 13 or later."
However, I have checked that I am using xcode 13.2.1 which works with iOS 15.2 SDK, running on macOS Big Sur 11.6.4 (well.... a 2015 iMac, kind of old though). I believe it is capable of building a project with iOS 15.2 SDK, but I just can't find where I shall tune (if necessary) to avoid it keeping using iOS 14.4 SDK to build my project. Could you please help me solve the issue? Thank you very much!!
The figures below show the environment I mentioned above:
Looks like you have multiple Xcodes installed, please make sure you have selected the correct version for your Command Line Tools
I found that it was an embarrassing reason which caused the problem I raised above. I think I am responsible for showing what was going on to all who have read this post, and especially to those who had paused to think about this issue.
In short, Xcode 13.2.1 does build the app using iOS 15.2 SDK.
I was able to successfully archive, verify in Xcode, and uploaded the binary to app store connect. However, I was not familiar with the app store connect and did not aware that there was another binary built with iOS 14.4 SDK which was left by my predecessor.
Though I tried several times rebuild and re-upload, I kept falsely submitting the old binary to Apple's reviewer.
That's it, and no bug or secret about Xcode using older version of iOS SDK to build apps, it is just not true. Xcode does build using its latest SDK. Again my apologies to those who also worried about this issue.

Can I mark builds by which iOS version the user has?

Maybe this isn't even the correct question but I'm not quite sure how to ask this
Since Apple released the iOS 10 beta, I put it on my phone to test my app. Expectedly, it would crash and I was able to remedy the situation with a new build of my app on my computer.
When my users install iOS 10, they're going to have the same issues until I can get this new version to them.
My question is can I upload my new build to the App Store but only for iOS 10 users? And if not, would this build work for users with iOS 9 since it has the Swift 3 language in it?
can I upload my new build to the App Store but only for iOS 10 users
Absolutely. Just edit the project and make 10.0 the Deployment Target. Done.

Apple Development: Release iOS 7 app

I will soon be uploading a new app to the App store. I have a question concerning the build version of the app. Does Apple still allow us to upload an app that has been build for iOS 7, since I know Apple is kind of forceful about staying up-to-date. I can't find anything about it while googling.
Thanks
The deployment target is the lowest iOS version your app is supporting and Apple doesn't limit that (AFAIK). So if you want to (and are able to), you can still submit an app that runs on iOS 5, for example (iOS 5.1.1 is the newest iOS version for first-generation iPads).
Apple does specify the lowest acceptable Base SDK (the libraries you're linking against) when submitting, though (they change this every few months/years and announce this to developers via e-mail). If you're using the latest non-beta Xcode, you're always fine. Submissions from Xcode beta version are never accepted.

iOS version affecting app download

I recently submitted an app to the app store and it was approved, however it appears that I'm almost the only one that can download it. I've asked family and friends to download it on their devices but they just get a message saying something along the lines of
"iOS version 8.3 or later is required."
This is clearly a problem because it limits the amount of downloads, is there a way around this to allow users with almost any version of iOS to download the app?
I really appreciate any help, thank you!
You can change the iOS deployment target in your project build settings
Or set the deployment target of each target (general settings).
You should be able to lower down to 7.X with a Swift-written application.
Make sure you don't any API specific to iOS 8.X or that you handle those correctly.
In Xcode, click on your Xcode project and navigate to the General tab. Under Deployment Info, change your Deployment Target to the oldest OS version you would like to support. You must recompile and make sure to test on different OS versions, as you won't be able to call newer APIs if they don't exist yet in that iOS version.

Do I need to install Xcode 4.5 to submit iOS app to App store?

After seeing this cocos2d topic I became confused. Do I need to install Xcode 4.5 to submit my app to iOS App Store?
As the comments imply if your deployment target is ios5.1 or older you can use older Xcodes to do this. I just did this last night. That said, if some library you want to include was built against the new ios6 SDK, then you will probably not get your app to link. In this case you will have to update Xcode to 4.5.
Currently, if your app does not require any iOS 6 APIs or features, you do not need to install Xcode 4.5 to submit apps to the App store.
Apple may change this requirement at some unknown point in the future. For instance, when the SDK for iOS 4.0 was publicly released, Apple stopped allowing the submission of apps developed with the, over 1 year older, 2.x SDKs.
