I'm developing flutter app using flutter_tts library which is written on swift, so I have to use swift as build language for ios otherwise it won't work. Release build size for android is about 20-30mb, but for ios is almost 400 mb. This is not because of assets. I read about this problem and a lot of people said that this is because swift, so I created a hello world app and compared release build sizes: objc: ~20mb and swift: ~65mb. Unfortunately, I have no choice. Now Flutter build for ios is 10-15 times bigger than for android. 400 mb – it seems like a joke, obviously it's inappropriate. Even if I convert Runner.app to ipa file, the size will be about 200mb. This is too large size to download app from AppStore.
Am I doing something wrong? Could someone help me? Any help is appreciated!
