From what I’ve heard Corona can support iOS 8 minimum so I would like to support that in my build. The problem is when building there is only choice in iOS SDK which is 11.2. It says the target it set to that but I don’t know where that target has been set in my code? I checked it build.settings but it doesn’t seem to be in there. How can I change that target?
I’m using Build 2017.3184.
With iOS builds, you pick the maximum supported version and you get all versions we support. So building with 11.2 will get you iOS 8, 9 and 10 support as well.

Ok I see. But I’m using XCode 7 and Corona is saying there is a problem when trying to build. My Mac’s os is yosemite so that’s the highest version of Xcode I could use. I wanted to upgrade to El Capitan but at this point Apple won’t allow you to do that?? You have to upgrade to High Sierra which has the most incompatibility with various software so I really don’t want to do that.
You potentially could drop back to an older Corona build that still uses Xcode 7/iOS 9. However there is a great chance that Apple will not accept your submission since they want apps built with the latest SDK and latest Xcode.
Rob
I was looking at the corona builds and I can’t see which ones use which version of Xcode? It only seems to tell you with the stable build.
There is a link on the daily builds page that lets you page back thru the release notes. You can shorten that trip by skipping back to the public build version that supports the version you’re looking for and then look through the release notes to see where we changed the version.
Rob
@hasen,
If you want to use the ‘store install method’, then, “Yes”, you can only get the latest version.
HOWEVER
You can always upgrade to or install any version of OS X your machine will run. You just have to download the installer from Apple and run it manually.
Google this and you’ll find instructions.
Yes I checked the release notes but the notes don’t seem to say anything about which version of xcode, the sdk etc that it’s compatible with.
I went back and looked. Xcode 7 means iOS 9 as the build target. I’m pretty sure Apple won’t accept submissions with that old of a software. As of April 2018, *new* apps must be iOS 10.2 or later meaning Xcode 9.2. I don’t know about updating old apps, but there is a very good chance you won’t be able to update apps built against the iOS 9 SDK.
Rob
I asked on the apple developer forums and I’m informed that even using Xcode 6 is still fine?
Even if this isn’t true, I’m using Xcode 8.2.1 now which supports SDK 10.2 but the stable build 2017.3184 only supports 11.2, so the question again is…how do I know which version of Corona to use for SDK 10.2?
Like I was saying, it doesn’t seem to state anywhere in the release notes for earlier builds which version of Xcode or SDK they are compatible with…
Daily build 2016.3003 has this in it’s release notes:
Daily build 2017.3183 has this:
So somewhere between 3003 and 3183. 3167 says we moved to iOS 9.1. If you pick a build between 3003 and 3183, you’re likely to get something that’s Xcode 8.2 compatible.
At least that’s the information in the release notes.
Rob
Sounds like you don’t have much of an idea either :) . There’s 9.0, 9.1 between those builds, not to mention 8.3 etc. Maybe going forward the sdk or xcode version supported could be added into all release notes? Because I can’t imagine it was easy to find the information you found even.
I guess I’ll just have to randomly download builds in the range you gave until I find the latest build that works with Xcode 8.2.1. 
Btw what is this April 2018 email you speak of?
It’s not an email, it’s on their developer blog:
https://developer.apple.com/news/?id=02152018a
We may not always implement point versions. If you have to use 8.2, then use 3003.
Rob
Ok I guess that’s correct then. Very odd though to make such a big jump.
Actually there are several versions after 3003 that also work fine with 8.2. My point was, finding these is like finding a needle in a haystack because they are _ daily _ builds and only the ones which changed their supported xcode version have that included in the release notes. 3003 has the xcode version clearly written in the release notes but even version 3004 has nothing written there about xcode but it’s clearly the same.
It would be good to have it written in all of them. Maybe right now we have to update to xcode 9 because of Apple’s strange sudden new requirement, but up until now even xcode 6 was fine. So in a few years we’ll face the same problem again digging through hundreds of release notes trying to find the one with xcode 9 written in it.
Apple changes these requirements almost yearly. They seem to have removed the old post because the new one trumps it, but we blogged about it last year in May: https://coronalabs.com/blog/2017/05/09/apple-now-requires-xcode-8-3-2-for-submitted-apps/
I’m not sure where you heard that Xcode 6 was fine, but perhaps they are just updating existing apps. Apple pretty much makes this a requirement 6 months after releasing a new operating system.
Rob
That can’t be right unless all these people are wrong. These are all from last year:

I also found lots of threads in these forums in the past where people were asking which build they need to use for a certain version of xcode. Maybe just a list with the builds where the sdk was changed noted down would be enough to keep track of everything. Btw it took a while to find but the newest build that works with Xcode 8.2.1 is 3061.
Just my experience: I have some native apps and the last time I tried to upload a new app (sometime end of last year) 8.0 was the minimum required by Apple. Anything lower and it would throw an error.

With iOS builds, you pick the maximum supported version and you get all versions we support. So building with 11.2 will get you iOS 8, 9 and 10 support as well.
