I just updated Xcode to the newest Version (13.0 13A233). And what I immediately recognized was that when I was typing in a large class (1000 Lines or more) the typing was delayed like 1 or 2 seconds. This makes it really hard to type or even do anything with my project. It works perfectly fine in smaller projects with only 100 Code Lines per File, but it is really hard to type in bigger projects with over 30 files and 3000 Code Lines per File. This always happens when I use Xcode, whether I run the app on a real device or a simulator.

Things that could cause the issue in my case:

I removed the contents of ~/Library/Developer/Xcode/iOS DeviceSupport, because it took the device previously too long to launch, but I don´t think that this should have an effect on my Xcode typing performance.

I would really appreciate any help, because this issue makes my work impossible and really concerns me a lot.

I received a reply from Apple where they ask to check the forthcoming new update Xcode 13.2 RC: https://developer.apple.com/download/

I've been using it for two days and so far it looks like the issue is fixed there.

I'm using Xcode Version 13.2 RC (13C90). It's a little better, but I'm still having many instances where the entire UI hangs for a few seconds - so not fixed for me

Apparently it's been resolved in 13.2: " Project Navigator Resolved Issues Xcode performance is no longer affected when source code displays several warnings and errors. (84533671) " Of course we have to try it. It's not necessarily entirely fixed.

Running 13.2. The performance is maybe a little better, but the issue is certainly not 100% resolved and the typing is still behind.

Any updates on this? Been dealing with it for years. Every time I press a key there is a .5-1 second delay. Impossible to code like this!! Come on Apple, fix this please!

Chiming in in case the Xcode team monitors these forums. My team is nearly unable to work because of Xcode 13 slowness. Files takes upwards of 10 seconds to open. The cursor lags behind typing. About 10-20% of our time is spent watching the mouse cursor beach ball.

I'm left reeling at how shipping something like this is even possible -- the same people shipping the software are using it as well.

We're having to reconsider our entire dev toolchain, and ultimately, platform choice as a result (we're using Swift on linux).

@coderkid: i wonder if you have the same issue with Xcode 13.2 as it fixed this for me. although i never had this issue before Xcode 13.

Temporary solved!.

have no problem previous version of XCode (XCode 12)

but XCode13 is very slow typing. (13, 13.1, 13.2.1 all version has problem)

This is Temporary solution.

All close tap window of source in XCode
Quit to XCode, and reopen to XCode!
open only one source (will be open to tap of source.)
Try typing!

This is definitely not fixed in 13.2.1. 13.3 beta 1 I can't really tell because that has it's own issues preventing the project from compiling

The release notes of Xcode 13.3 beta 2 mentions "code completion" 12 (!) times. Unfortunately I cannot test it yet, since it requires macOS Monterey. Did anybody tried it?

I'm using Xcode 13.2.1 which suffers as well of this issue, typing text is visibly slow. Things improved dramatically after disabling "Code folding ribbon" from Preferences > Text Editing.

Using the latest Xcode 13.2.1 (13C100).

I have noticed that if I disable Source Control from Preferences, then I notice an immediate improvement in opening files/storyboards, autocomplete, etc.

I tried with enabling just source control and disabling any of the "fetch automatically" sub-options, but it caused the same beachball'ing I had before.

Was using Macbook Pro 2017, I thought it was my MBP getting slower. And now that prove me wrong. Having M1 Pro Max 64GB, Xcode still being the worst IDE I ever had in Mac. Freezing storyboard and code typing.

Beach balling all the time... Not responding all the time... It's impossible to use this.

13.3 Release still typing laggy.It looks like that xcode scaned all context while typing. 31551647343753_.pic.jpg
