any idea how to get the swift upload network traffic down? My 500K objc ipa ported to swift http://mro.name/ShaarliOS http://mro.name/ShaarliOS now is ~8MB (OTA test ipa), ~28MB for production upload causing ~300MB traffic until finally uploaded via xcrun, taking 1h on my rural uplink. Has anybody an idea how to get back to sane dimensions?
