You can download 6.4 from the link in my first post. I actually ended up doing that rather than using 7.0, because we needed to submit to iTunes and didn’t want to spend extra time testing xcode 7.
Thank you Alan.
Managed to get Xcode 6.4 installed ok and to finally do a successful build but I had to ignore this message:
"The version of iOS SDK (8.4) that’s installed on this computer does not match the target iOS version (8.3). You may encounter issues building or incompatibilities at runtime.
You should consider updating your version of Xcode or using xcode-select to enable a compatible version."
What should I do about that?

Update Corona SDK to a daily build 2708 or later. We are up to 2720 and that’s the daily build I would currently recommend.
Rob
Have installed 2720 - using it to build produces the same error message.
2720 will require Xcode 7.
You need between 2668 and 2719.
Rob
Successfully setup Build 2719 - completely successful build!
FYI
-
It took me a while to find the app file as it is now in the Payload folder (a good move of course!)
-
Despite selecting “Show in finder”, this did not happen.
Thanks to you both for your help and perserverence (note to self: don’t upgrade Xcode!)
I hope that if anyone ever solves my original problem they will post the solution here.

Unfortunately, Apple will make sure this is short lived. If they follow past history by February you will be required to build using the iOS 9 SDK. This will require you to have Xcode 7. But before we get there, Apple will have probably released iOS 9.1 and perhaps 9.2 which will require Xcode 7.1 and 7.2 respectfully. Our next public build will be based on iOS 9.0 so you will eventually need to solve this Xcode 7 issue.
As far as the being able to find the app, we are now outputing a .ipa file for delivery to the store instead of a .zip file. Development builds will still be .app files I believe.

Hello everyone!
#prh: Thank you very much for submitting this issue!
Yesterday I had the same problem as yours. My situation is: Corona Public Release 2015.2646 + upgrade to Xcode 7.0.1 = error on missing copypng and codesign_allocate.
So, up to now, the solution (Daily Build 2015.2719 + Xcode 6.4) is still the same?
The file I get this way doesn’t fit iOS 9, does it?
Apple will approve it?
Many thx for relieving my anxiety!!
I believe it will run on ios 9 too.
As for xcode, when you want to try new version, I suggest you download it manually and do a multiple instance installation then use xcode-select to select the new version. This way, if error happen, you can easily go back to previous version.

Thx, So Lin
Now I have Xcode 7.0.1 installed and have just downloaded 6.4 dmg.
I don’t know how to perform a multiple instance installation. Please can you give some hints?
The simplest way to solve this is for everyone to get 2728 and run Xcode 7.0. That is the magic combination for now. You have production support for iOS 9. Apple will have no problems accepting these builds. We have all of the new build dialog issues settled. You may still have to install Application Loader from the app store. You may have to set some environment variables for Android, but the build dialogs tell you what you need.
Rob
Hi Slvnnn,
Try a google search of “how to install multiple version of xcode”.
@Rob, doesn’t the Application Loader come with Xcode?
So Lin
Thanks Rob - have followed your advice and all is good. For others who are like me and are not good at the behind-the-scenes stuff, I have made careful notes of everything that I did - hope this helps someone:
-
XCode Forced Quit.
-
Renamed Applications/Xcode to Xcode6_4 (5.85G)
(NB Xcode_6.4.dmg is still in the Downloads folder) -
Downloaded Xcode 7 from https://developer.apple.com/downloads/ (3.6G)
-
Installed Xcode 7
Now have new Applications/Xcode (7.82G) -
Ran direct from Applications folder (lots of patience needed)
checked version is 7.0 -
Downloaded http://developer.coronalabs.com/downloads/coronasdk/CoronaSDK-2015.2728.dmg
-
Installed
Now have Applications/CoronaSDK-2728 -
Ran Applications/CoronaSDK-2728/Corona Simulator
-
Built IOS app suucessfully.
Note “Show in Finder” now works. -
Used Xcode to load directly to my iPad - all ok.
Peter
A version of Application Loader ships with Xcode. However the standalone version of Application Loader ships with some cool utilities that lets Corona SDK upload the file to the store for you.
Rob
Hi Peter, I ran into the exact same problem you ran into - I updated xcode to 7.0.1 and used daily build Version 2015.2730 (2015.10.2) and it seems to be ok now (Although a little slow to build, but working!) I’m glad you got it fixed, posting it here really gave me a leg up 
Hi Matthew,
Good to hear that my horror trip has helped and interested to see that you have moved further along with versions. I think I’ll stay where I am for the moment.
Best … Peter
The current daily builds include iOS 9. It says beta, but starting with build 2708, it’s using the GM seed which you can submit with). If you want to to use iOS 9’s SDK, you need Xcode 7. If you want to use the iOS 8.4 SDK you will need Xcode 6.4.
When we release the next public build, it most likely will only have iOS 9 and you will need Xcode 7 at that point.
Rob
Thanks Rob.
Just to be clear, when you say:
When we release the next public build, it most likely will only have iOS 9 and you will need Xcode 7 at that point.
You mean that it will only have the iOS 9 SDK, not that apps built with the next public build will only support devices running iOS 9?
Apple iOS apps run on the SDK they are compiled against and two older versions of iOS. So iOS 9 built apps will run on iOS 8 and iOS 7. If you need to still support iOS 6, you would need to build against iOS 8.
