Thank you a lot for your answers! I have submitted my playground just a couple of minutes ago. 🤞

I have two .swiftpm files now. One I have been working inside for 2 weeks now, and one I created today and just copy-pasted the files from the first playground. The thing is that even though these files are identical, they have a size of 26mb(first file) and the copy file is only 5mb. I will only submit the smaller one. My concern is that Apple will look at the creation date of the new .swiftpm file and will not believe I have completed this project in a single day.
