Can I upload Xcode builds on macOS 10.12

Question

Will I be capable of submitting an app with Xcode 7.3.1 while on the macOS 10.12 beta? According to this post, it is possible to run Xcode 7 alongside macOS 10.12.

Answer 1

Yes, you can! But if you're tying to do this, you will find two problems.

1. no .app file provided in bundle

Build with Xcode 7.3.1 then upload using Xcode 8 [Beta]. This will allow you to upload the archive.

2. When trying to submit to the store you will be faced with this error message:

   New apps and app updates must be built with the public (GM) versions of Xcode 6 or later, OS X, and tvOS SDK. Don't submit apps built with beta software including beta OS X builds.

This is because your archive contain the Sierra's mark! I just solved this problem yesterday.

When you archived your app, find your archive in the Organizer, and then:

• "Show in finder";
• "Show package contents";
• In the "xx.xcarchive" file, find the "Products"-"Applications"-"xx.app"(xx is your app's name), "Show package contents" again;
• Finally, you can see there has a file named"Info.plist", open it;
• Edit the value with a key named "BuildMachineOSBuild", I just change it to "15F34"(it's "El Capitan 10.11.5" 's version);

After that, you can upload this archive use Xcode or Application Loader, whatever you want!
