Assume your iPad’s storage is full. What would happen to your app when use saveImage()? @Simeon
Why not test it and report back here 
I thought someone maybe knows that already…
Most apps just crashed when I tried to open them or do anything in them when I was completely full, even including the Photos app (which makes it a bit hard to delete stuff). Some others simply didn’t save anything I had done in them.
@SkyTheCoder thank you for sharing your experience.
I’ll report back as soon as I’ve tested it with my app…
@se24vad I’m only one fourth full on storage so I’ll go download the extended cutt of The Lord Of the Rings and get back to you.
@Goatboy76 thank you! I’ll wait for your report! - …since I even haven’t so much data to fill up 32GB of space
EDIT: In the meantime, I’ve successfully implemented unlimited undo/redo functionality for my drawing app! 
I’ll share the code when all testing goes well…
@se24vad Sorry to get your hopes up but I was just cracking a joke at how long The Lord of The Rings movies are, sorry. I really dont have the means to fill up 32 gb either.
didn’t get that no problem. will test ist out somehow 
PS: Here is the unlimited undo/redo functionality in action. Excuse the missing GUI.
