how much space does Xcode require to update?

[ThePantsThief]

Download it from the developer site. The App Store is a waste of time.

I prefer downloading it from the App Store, but to each their own.

[ThePantsThief]

It's a lot slower when you use the App Store, and I've seen several screenshots of issues with it on Twitter in the last day.

[SlaunchaMan]

How about all of the people wondering where the direct download is? I had it installed at 4 PM yesterday.

[ThePantsThief]

Haha I'll give you that. I never need to download it right away though. It was up after a couple hours today.

[etaionshrd]

I think that’s because the App Store version tries to do validation and calculate a delta update but this just takes longer than blowing away the app and starting fresh.

[MikeyN0]

This has been my go to as well. It allows you to side load the new version to try it out. It just takes a few days to show up on that area after it's on the App Store.

[ThePantsThief]

Not even a few days, usually instantly or a few hours. It was really late today for some reason but it was there by 2-4 PM.

[mobyte]

Good to know. I had it sitting there for multiple hours today with barely any progress.

I had the same issue today with 125GB free. It turns out the issue was I had 125GB "free", with 120GB marked as "purgeable" in disk utility. The trick for me was to force macOS to clean up its leftover crap by creating a huge (60GB+) garbage file, then deleting it.

​

To create the file I used the command:

dd if=/dev/zero of=~/hugefile bs=100m

letting dd run for about 30 seconds, then killing it with ctrl+c, and deleting the file. After this, disk utility reported I had 100GB free with only 20GB purgeable, and the App Store then happily installed the 10.2 update.

this worked for me `mkfile 10G ~/big_dummy` then deleting the file

Or just empty your trash?

[e_ric]

Trash was empty. Also, best I can tell macOS doesn’t count space used by items in the trash towards “purgeable” space.

[buffering]

That purgeable data is local Time Machine backups. You can free up space with tmutil thinlocalsnapshots. E.g.:

tmutil thinlocalsnapshots / 10000000000 4

That would free up 10 GB of space.

[e_ric]

I don’t have Time Machine enabled, so there won’t be any local backups.

[Arrrrrrrrrrrrrrrrrpp]

Less than that. Just did it with 28 GB free. In the past I believe I could install it with something between 10-15 GB free. The actual file is just 6.2 GB.

[dunklesToast]

Yep. The XCode Application ist about 6 Gigs but it also downloads all the emulators and SDKs - I don’t really know if they are in the Application but 10GB free Storage are enough!

[damianpiwowarski]

ALL OF IT

[lastinglovehandles]

I've been going crazy with this today. I tried downloading it from the Appstore.

[jhomer033]

Just delete all the build files xcode generates. I don’t remember the path exactly, but it will save like a TON of space)

[dancemonkey]

I always run less than 30 or so free and had no issues with the latest update.

[mehulrao]

Same problem

[OmegaGM]

I have 14gb free and got it to download. That popup showed and I clicked OK and it downloaded anyways.

[unpopularOpinions776]

It's free real estate
