What is the current limit of the game app size in App Store? The current game I am developing would be about 5~6GB, it may be increased as I include more contents. I couldn't find any documentation related to this in apple websites and I looked at some old posts in the internet that the limit is 4GB. If so, is there a way to exceed the limit?
Maximum game app size in App Store
There are two limits - one is the max size for download over the air, and the other is max size in the store.
You're way over the max for OTA, so...
4GB, uncompressed, is the max in the store - see Maximum Build File Sizes
There is no way to exceed that limit and still have an app in the store, however, the solution over the years when the asset requirements go higher is still the same...download from a server of your choice post-install. Apple provides hosting, Amazon, DIY on your own servers, etc.

Good luck.
