Hi - been a while and I note I can’t upload the .app file that Corona creates directly into the app store. Downloading and running “Transporter” I note than when trying to upload it is asking fro an IPA or PKG file? Looking in the doc I can’t see any mention of transporter/ipa/pkg? https://docs.coronalabs.com/guide/distribution/iOSBuild/index.html
Take a look here and let me know if it helps or does not.
I don’t have my Mac setup right now, so it’s hard for me to verify the steps in order to help, so I’ll have to hope the link above helps OR that another user us is a more regular Mac user can answer.
Here is a direct link to the Transporter https://apps.apple.com/us/app/transporter/id1450874784?mt=12
Dang. I misread your post.
You have the Transporter, but you’re having trouble with the build.
I’ll have to rely on other Mac users till I get my VM of OSX running again. Sorry for the time waste.
How do you/windows developers upload to Apple? Do you have a way to create an IPA or PKG package with Corona?
Nope. I used to use my MacBookPro, but now I use OSX in a VM to do my builds.
There is no avoiding using OS X to do builds for the App Store.
How do you upload then? i.e. do you create an IPA or PKG file somehow?
Not sure if I have understood your question correctly, but if you select the option “Send to App Store” when building from the simulator it will automatically create an IPA file for you. Then you can just use the Application Loader to upload that build to your App Store account.
And as @roaminggamer said, I don’t think there’s any way to upload an iOS build without using MacOS.
The IPA file is basically just a zip file containing your app directory. See this blog post I wrote a few years ago when I needed to upload a dev build to some 3rd party services: http://bitstopixels.blogspot.com/2017/02/create-ios-ipa-file-from-corona-sdk.html
thanks Markus - that’s what I needed 
The only thing now is that in the mix I updated Xcode to 11.5 to try this and now I note I’m ahead of Corona SDK in terms of version, getting the below mentioned error…
Do I need to find an Xcode 11.4 binary to install to roll back from Xcode 11.5 do you think?
The version of iOS SDK (13.5) that’s installed on this computer does not match the target iOS version (13.4). 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.
Do you want to proceed with a build?
Good.
I think that is just a warning, saying that there MAY be issues because of the iOS version mismatch. Normally everything will work just fine from my experience. I would probably just go ahead and build, and of course test to make sure that nothing crashes.
