Как выкладывать iOS сборки на сервер

Сервер обязательно должен быть с SSL

Необходимо загрузить файл сборки на сервер в какой-либо каталог и сохранить ссылку на этот файл. Пусть ссылка на сборку будет https://mysite.com/builds/my-app.ipa

Создать на сервере plist-файл с следующим содержанием

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
