As part of the countinues integration process of my iPhone application, I want to create a process that will automatically upload the app (.ipa) file to the apple app store.
You should use application loader tool: altool --upload-app -f file -u username [-p password] [--output-format xml]
As describe in: https://help.apple.com/itc/apploader/#/apdATD1E53-D1E1A1303-D1E53A1126
