application loader submiting with metadata

I have my app running correctly. I have run the Package maker to produce a pkg

Nevertheless, if I try to upload with the Application Loader it always returns me :

• The archive is invalid. Unexpected productutil output: the product Meta-data must be present
• Product archive "/Users/....path to my app/Myapp.pkg is a directory"

This should be a littl开发者_StackOverflowe thing but I spent hours and didn't find out.

Application loader expects a ZIP file. The ZIP it expects is made from the .app folder - Compress that and upload the resulting .zip file.

Compress your project.app file,so a .zip file will be created.You can use this .zip file in your Application Loader.

Remember to make a distribution binary with your distribution certificate if you are planning to upload this file on itunes connect.

Cheers

it's weird: the Browse dialog for Application loader only accepts .pbk files. Drag&CDrop via the dock only accepts .zip files - and dropping a zip file too gives me the described error messages. choosing the .PKG via the browse dialog works on. strage, but hopefully this helps?
