Hi, I have a video file of about 4GB.
When I try to read the file by using the function Data(contentsOf: <URL>, options: <Data.ReadingOptions>). It will be leak memory and crash the app.
How can I control this issue?

How can I control this issue?

You usually do not load whole video content into a Data in iOS apps.
How do you want to use the video file?

Thanks for explanation. You have no need to load all the content when you want copy files.

my iPhone.

Typically you’d do that using copyItem(at:to:).
