I'm trying to build Unity project in Xcode, it is a simple 2D project of games like Crossword,Trivia, MCQ questions... when i archive and download from Testflight the game is 2GB in size, any idea what to do or why is it so big ?
as @MickyD explained a lot of stuff that would help, however the problem was with the assets "sprites" imported were too big, so since I had like 3k sprites, i couldn't re-import each one of them as a POT so I compressed them inside Unity by overriding for IOS
and if the sprite lost a lot of quality I would increase the size to 2048 or try another format.
