I made a new app with Animate CC 2017 and AIR 23.0. After successfully creating the ipa file I tried uploading the file with Application Loader 3.1 and got the following error: Error ITMS-90168: “The binary you uploaded was invalid.” How do I know what the problem is?
Which version of Application Loader are you using?
Application Loader 3.1
They are up to 3.6 now, and that error could happen when using an old version. I can't see a download page for that, so you would just need to get a later version of Xcode.
