As the issue has been reopened recently, the AppBuilder team applied changes to the publishing feature on another environment. Please, perform the following steps on your side and see if the iOS publish will succeed:
- Open an incognito browsing session.
- Navigate to https://platform.telerik.com/#workspaces and log in with your credentials.
- Then, in the same browser navigate to https://devapp.icenium.com/Mist/?tap=off. This is a copy of the AppBuilder integrated cloud environment, that has the fixes for the publish feature applied to it.
- Try to publish your application from there.
We expect that you should be able to publish successfully from this environment. However, if error occurs please provide the support team with a Fiddler log for the whole process in a separate support ticket. Note that, the support ticket is strictly confidential and as a private communication channel, it is save to send your Fiddler logs there. Any other communication channels (e.g. Forums) could lead to sensitive information leak and we do not recommend them.
