Xcode 7.3 is excruciatingly slow when loading Storyboard IB - xcode

I recently upgraded to Xcode 7.3. I found that loading up the storyboard can take anywhere from 5 to 10 minutes to complete(and may sometimes result in a crash). I've restarted my Mac several times. I uninstalled Xcode and reinstalled it to no avail. I then cleared my Derived Data as well as com.apple.dt.Xcode to find that this did not help either. Is anyone experiencing a similar issue and possibly has a solution?

Although this actually might be an issue with incremental changes in Storyboards with Xcode 7.3 you can always speed up build times by creating multiple small Storyboard files in favor of a big bloated Storyboard.
Xcode can then reuse already built Storyboards in subsequent builds (as long as they are not changed) instead of building the complete bloated Storyboard over and over again even for small changes.
Apple even has a guide that might help getting this started.
I hope that helps!

This is really annoying bug/issue with XCode 7.3. So, If you have an hour or so to spend you can download and install XCode 7.3.1 Beta from here https://developer.apple.com/xcode/download/
It seems that this issue has been fixed in this version (at least it works for me).
Edit: OK. After a few minutes, Interface Builder became extremely slow again. Changing only one property can take up to 15-20 minutes.
After some research I have figured out that autolayout constraints were the cause of this issue, BUT only if you have a combination of some components present. I had a segmented control inside a navigation bar. When I removed navigation bar and placed segmented control in a simple UIView, all issues were gone and IB was smooth again.
Hope this will help.

I am using Xcode 7.3.1 and had the same problem. My problem was solved by disabling source control.
Go to Xcode->Preferences->Source Control and then Uncheck the Enable Source Control. Worked for me.
Thanks.

Sometimes the storyboard gets slow because of unresolved errors of autolayout. In my case i tested by changing screensizes and it showed me some errors on different sizes. Once i resolved those errors the storyboard was working fine. Please confirm

Yep I had the same problem. In design mode, it's Autolayout that is causing the 5-10 second delay between edits, especially if it's a large storyboard. Turning off Autolayout in the storyboard at design time fixed the issue for me:
Open project
Select storyboard from the Project Navigator
Open the file inspector
Under Interface Builder Document uncheck 'Use Autolayout'
If you need Autolayout at run time, I recommend you layout your Storyboard in design time with this off (to avoid those long delays between edits) then turn it back on afterwards. Or, turn Auto layout on programatically. Or better yet, split your storyboard out into smaller storyboards.
Referenced this question: Can I disable autolayout for a specific subview at runtime?

I got the same issue recently after I updated the OSX to 10.11. Xcode 7.3 will take almost 5 mintues to respond when I just change the button's font (or anything else change). This made me almost crazy. Incidently, just for a try, I updated Xcode from App Store to 7.3.1. Then I was happy to cry when I opened the storyboard and changed the attributes. Xcode responds smoothly.
So please try Xcode 7.3.1 for your problem. Hopefully you can be happy with it.

Quitting Xcode 8 and reopening it breaks constraints in my Xib file

encountering a very frustrating issue. I have a Xib file for my custom UITableViewCell. I set the constraints up and there are no warning or issues and the app runs fine. However if I close the Xcode and reopen it they are set to different values and the entire view is broken.
There seems to be no way to fix this, even if I reset to a previous commit the view remains broken. Has anyone else encountered this? Is there a fix?
Please try Xcode 8.1 which addresses the following:
Xcode 8.0 did not always restore view frames from storyboards and xibs when layouts were ambiguous. Xcode 8.1 fixes several of these issues. If you have encountered these issues, resolve the ambiguity in the Auto Layout issues and update frames. Xcode 8.1 will persist them correctly. (28221021, 28244619)

Xcode 6.3 freezes when I quit the Main.storyboard

I'm experiencing a very strange error: my Xcode is freezing when I quit a certain storyboard of a certain project.
When i open Xcode, the xib shows up normally, I can even edit it and save it. But when I'm trying to open another file, any other file, it freezes forever.
I tried to delete every temporary files as described here, or here, or here, but the problem still remains. Ah, and... re-create my xib is obviously not an option...
Any other idea?
EDIT:
When I delete myProject/[project.xcworkspace/]xcuserdata (s), I can navigate in my project as usual while I don't open the storyboard. otherwise my problem comes again.
Since my post about this problem, I saw it on other projects. I'm pretty sure this was linked to custom fonts in xib, because it often happened after an Xcode bug rendering custom fonts.
Few days ago I downloaded the last Xcode version, 6.3.2, and the problem did not bother me again. So it seems to be resolved.

Xcode 6.1.1 crashed changing TableView to Static Cells

I am trying to create a Table View Controller in my storyboard and when I change from "Dynamic Prototypes" to "Static Cells" Xcode stops responding until it eventually crashes.
What I tried so far:
Re-installing Xcode;
Clear Xcode folders under ~/Library (including DerivedData);
Creating in a new project (still crashes);
Ask a colleague to create a Table View Controller with static cells in the same project. He can do it on his computer. I can see the Table View on my computer and even edit rows, but I cannot add sections.
Tried both Swift/Obj-C projects, with or without Core Data;
I am using XCode 6.1.1 (6A2008a), the same as my colleague.
Please help! Thanks!
Yes , I have faced similar problem .please try with Xcode 6.3.x or later version .
Not a fix but may help some. I noticed this was only happening to me when I had two windows of my current project open. Was reworking a storyboard, so I had the old and new side by side. When I closed the windows of my project that I was not currently editing, Xcode did not crash. With more than one window open, editing a Static Table View would crash Xcode EVERY time.
I found a temp Fix. I also noticed that my dock isn't working fine (I can drag and drop things into it or in it). So I rebooted the mac and this fixed the dock problem, I tried quickly in Xcode and it worked. I guess it's something with Mac OS not just Xcode

Storyboard Preview do not match simulator or device in xCode 6

I have been trying to figure this out for a long time now, either I am stupid, or Apple hav just made this really tricky. Storyboard Preview do not match simulator or device in xCode 6! I have added constraints so that the app looks just fine in all screen sizes in preview but it looks messed up when I run it in the simulator or on my device. help!
do you need any screenshots to answer my question?
I know other people have had the same issue but I can not find any answers.
The storyboard "Preview" doesn't match the simulator if you have any constraint errors/conflicts. I was having this problem, and found this question while searching for an answer.
Once I got all of the conflicts resolved, the Preview worked. It seems like the preview should consistently show what the simulator would show to help during the setup, but it's all out of whack if there are conflicts.
Using Xcode 6.3.1 and I was having the same problem(s). What I discovered is that you are missing constraints...
open main.storyboard in your "Structure" column you should see some red arrows, single click them and you should see what constraints you are missing.
Can confirm that this was resolved after taking care of all warnings and errors related to Auto Layout.
I just fixed my size class problem by having my constraints be set for compact width / regular height. When I set constraints specific to compact width / any height, it ignored my custom values.
Hope that helps. Took me forever to figure out because the description lead me to believe my custom layout would cover more devices with the latter choice.
Make sure you've got the latest xcode installed. I had the exact same problem before realising there was an update waiting. Now I've installed the update my preview matches what appears on the simulator.
How I got this fixed is by updating Xcode to the latest version. And then recreated the NIB/Storyboard files that were created using the previous version of Xcode. It started working. Weird fix :/
This is a constraints issue.
Some constraints are not set properly or not set at all. Once all constraint issues are resolved, you would see the simulator and preview matching exactly!
For anyone experiencing this issue in Xcode 8 and all all your constraints are in place (i.e. no warnings or errors) what solved it for me was quitting the simulator and restarting the app through Xcode again.

xcode storyboard reverting in compile

I started having some very odd behaviour in Xcode 4.5 recently. I made a change to a UITableViewController with static cells but the changes did not appear in the simulator and neither did my code changes. I removed the app from the simulator and ran clean on the project, then started again and all the changes appeared. I made another code change, ran the debugger via simulator and once again I saw my old UITableViewController values and my code changes were absent. This project is using storyboards, but I am not sure if this problem is related to just storyboards given my code changes are reverted as well.
I am deeply confused here. Not even clean fixed this issue.
Any thoughts or suggestions?
Somehow my simulator got all messed up. After resetting the content and settings, it is all working properly again. Very odd.
