Try the application loader. sometimes I run into the same problem with Xcode7.2 and then try to download the application using Application Loader. It worked fine.
- Downloading an application using Application Loader ....
Step 1) First, create your application and IPA export your IPA, created with the App Store iOS deployment.
Step 2) Right-click on the XCode (the dock) → Open the Developer Tools → Application Loader
Step 3) Select the IPA (which is saved for the deployment of iOS app store) and Next to download. it takes a little time, and after a few minutes it will be shown on the connection itunes.
in a few minutes it will be displayed on itunes connect.it is very simple and fast compared to xcode. Hopefully, it will help you !.
