Auto layout Failed to Render - xcode

I have been getting this error only on occasion when I work on my storyboard:
Failed to render and update auto layout status for Category
ViewController: IBAppleTVSimulatorAgent.app failed to launch
I usually just close and reopen my xcode and the warning goes away, but could someone please tell me as to why this is happening and how I can have a more permanent solution rather than just restarting my xcode?
Thaaaanks!

It's a glitch in Xcode 7.1 beta 2 when laying out tvOS storyboards. It's just something to put up with until they fix it, hopefully in beta 3.

I was also facing the same issue while developing TV app.
I deleted the Xcode 7.1 beta 2 and
I reinstall the Xcode 7.1 beta 2
this fixed my problem.

Xcode 11 can't launch CarPlay audio application

In Xcode 11 GM Version can't launch Car Play audio application in the simulator.
Simulator stuck on the loading screen, then show "Unable to connect" error. Sometimes shows only black screen or crash on app launch.
While debugging, I see that methods from MPPlayableContentDataSource and MPPlayableContentDelegate won't fire. On Xcode 10 all work fine, so it's looks like some bug in new Xcode 11. Maybe someone knows how to solve this problem?
Thanks indeed.
I submitted a radar (FB7514196) to Apple.
You can see a copy of the radar here: https://openradar.appspot.com/radar?id=4997629368860672
Just installed Xcode 11.3 and I'm still having this problem. Contacted Apple via the Feedback Assistant and the response was:
Please ensure you're providing a prompt response to
MPPlayableContentDelegate and MPPlayableContentDataSource when you app
launches on the car screen. You have a few seconds after launch before
we show this timeout screen.
The first thing I do when starting the app is to set up this delegate and data source, so that's not the issue. Maybe something related to setting up CarPlay changed in the iOS 13 SDK.
Xcode 11 and Xcode 11.1 seem to contain a broken CarPlay implementation. Xcode 11.2 (beta-1) seems to work much better here. That said, the CarPlay simulator is finicky anyways and you should really use a real head unit to test your programs. I have found simply closing and reopening the CarPlay simulator to help with many issues, btw.
Still the same issue here with XCode 11.2.1
Anybody found a solution?
The CarPlay simulator has always been a total disgrace - for years!

Xcode 10 storyboard UI components are not visible and painfully slow?

My code was working fine (showing UI properly) when I had Xcode 9 and I removed it from the application folder (could not update as it had installed using another apple id) and reinstall the Xcode 10 from the Appstore.
Now Xcode storyboard not showing any added UI elements colors or anything and I removed Xcode 10 and installed Xcode 9 again but problem remains same.
UI screen shot of storyboard.
I tried removing Xcode in this way:
/Applications/Xcode.app
/Library/Preferences/com.apple.dt.Xcode.plist
~/Library/Preferences/com.apple.dt.Xcode.plist
~/Library/Caches/com.apple.dt.Xcode
~/Library/Application Support/Xcode
~/Library/Developer/Xcode
~/Library/Developer/CoreSimulator
Then I tried installing macOs Mojave and install XCode 10 again from the Appstore. Issue still remains. I tried cleaning derived data, xuserdata and everything.
Try cleaning your project using "Command + K"
and run your project again!
Hope it works!
I encountered the same issue that you are facing in my case i had xCode 10.0 installed and everything was working fine. As soon as I installed version 10.1 I faced the same issue that you're facing but the good thing was i had xCode 10.0 installed at the same time so I switched back and everything was working fine.
From my point of view my system(Mac-mini mid 2011) was lacking hardware specification that was required for xCode 10.1 also had very low graphic processor in my mac mini. If you install the same version in a MacBook or any other system having higher specification you'll face the issue. I hope that helps.
I was stuck on this all day. One of my coworkers suggested removing occurrences of IB_DESIGNABLE & #IBDesignable. This fixed the issue for me. It still lags sometimes but doesn’t go invisible anymore.
If you have multiple xib files then just try to switch between or Try moving to launchScreen storyboard and then switch to main storyboard. I think this is just loading issue.
Reinstall Xcode. That worked for me.
Click on library button(Circular Button) which is left to hamburger sign(Top Bar Right Side). Elements will be popup on your screen then you can choose elements.
try
xcrun simctl erase all
it helped me with the same problem

Can't use safe areas in Xcode 9 after upgrading minimum deployment target to iOS 9

I have just changed my app from supporting iOS 8 and up to supporting iOS 9 and up. I believe I've done this properly, since when I now build my app, I'm getting warnings for everything in the app which was deprecated in iOS 9.
I am using Xcode 9, GM seed.
The problem is that I cannot enable the "Use Safe Area Layout Guides" toggle in any of my storyboards. When I do, I get a warning "Safe Area Layout Guide before iOS 9.0". Is there some additional setting that I need to update? A clean and build did not fix the problem.
Just deselect "Use Safe Area Layout Guides" option, which should fix this.
A screenshot below may point you the right direction.
Hope this image can help
When you changed the deployment target, did it automatically change the deployment target in your storyboard? (File inspector when opening the Storyboard)
Did you update the deployment target in both the Project and in (all) your target(s)?
Project:
Target:
I didn't try quitting Xcode and restarting it before posting to SO! Sorry! The answer is, quit Xcode and try again.
Simple fix.
In file inspector for the view, look for Builds For in Interface Builder Document and in there select iOS 9 and later.

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)
(If not, please file a bug with http://bugreport.apple.com.)

Illegal Configurations Xcode 6.4

What are illegal configurations and how do I fix them?
I have 3:
Launch screens may not use instances of IBUIExitPlace Holder.
Launch screens may only have one top level object, which must be a UIView or a kind of UIViewController.
Launch screens may not use instances of IBUIStoryboardEntryPointIndicator.
I'm converting my Swift 2 code to Swift 1.2 so I can upload my app to the app store.
Thanks in advance!
I just stomped with the exact same issue.
I think you can reproduce the issue with the following steps:
Create a Launch Screen.storyboard using Xcode 7 beta 5
Open Xcode 6.4 and try to build the project, it should fail.
What I did to fix this was to delete the Launch Screen.storyboard created on XCode 7b5 and create a new one on XCode 6.4.
Please let me know if you try this solution!
Encountered the same issue. This issue is generally caused because of creating a Storyboard using XCode 7 and using the same Storyboard file in Xcode 6. Follow the below steps to solve the issue.
Delete the LaunchScreen storyboard created by Xcode 7.
Create a new LaunchScreen storyboard using Xcode 6.
Clean and Build.
