I've been trying to download iMovie for a long time, and I have never had enough space. I have an 8 GB iPhone 5C. I have a project in particular I want to get done, so I deleted all my other apps (other than pre-installed ones, of course) in order to try and download iMovie. According to iTunes, after this, I have 2.04 GB available. I figured this would be enough to download iMovie and get this project over with before deleting it and redownloading all my apps again. And, yet, again I got the dreaded error code declaring that iMovie could not be downloaded at this time and that I didn't have enough storage. I don't know what to do. I know that apps are always more than the number that appears on the App Store page, but even ~2 GB should be enough to download iMovie, right?
How can I download iMovie?
