I used the AWSS3TransferUtility to download the files. Here is my code snippet https://stackoverflow.com/questions/74046858/swift-unable-to-downlaod-larger-files-from-aws-bucket-using-transfer-utility

I also noticed that the issue is there mainly when I tried to connect more than one device for transferring files.

But multipeer connectivity can reach up to 50+ feet i think. So what is the actual issue here

Now I figure out that the speed issue is related with distance between the devices. It is almost 50 feet. So my airdrop wont reach that far.
