IOS unity taking lot of memory
I have integrated unity with IOS, I use unity to play games and doing other things on IOS. Initially when I open IOS app it takes around 70MB, after loading unity it becomes around 400MB other than the memory that is being used during gameplay. After game over I move back to IOS screen but it still takes same 400MB because unity is still in memory. I want to unload unity completely after game is over and when I move back to IOS screen, and if I choose to start another game on IOS screen, I want to load unity again to play the game. How should I achieve this? How do I unload unity from memory. I am having lots of memory crashes because unity and some scripts are still in memory. I used GC and Resources.unloadunusedassets() for some memory release. Its helping a little bit.
I am using unity 2019.4.7f1.
