Xcode 6.3.1 Simulator UI Errors - xcode

Since updating to Xcode 6.3.1, my Simulator isn't rendering my UI elements consistently with autolayout.
My detailViews render the same IB layout inconsistently, with one view truncated while the other view is fine. Both are properly constrained. This only happened after installing the new update.
Has anyone else encountered this problem?
Thanks

When you say "simulator", are you talking about the iOS device simulator, or the Preview Assistant?
Does this issue reproduce on device?
Can you post a screenshot showing all of your constraints for the affected view?

My iOS simulator is rendering with glitches

I have a 2019 16-inch Macbook Pro with an i7. My iOS simulator is showing terrible behavior on Xcode 12 and 13. The rendering happens only partially. I start typing but only top part of the TextField updates. When I pull my modally presented controllers up and down, it leaves glitches and artifacts in the render whenever I release the mouse pointer from the window. Only when I drag and click something in the simulator, only then the screen updates properly.
I have tried resetting the simulator and the machine, and different versions of Xcode AND or simulator iOS and nothing helps. I also have not found too specific mentions of this issue online.
This is a known issue that was fixed in Xcode 13. It primarily affects the iPhone mini so you can workaround it by using a different simulator.

Xcode 10.1 How to fix User Interface Inspector "Capturing User Interface" not working continuously loads

I updated to Xcode 10.1 today, and noticed that when trying to utilize the User Interface Inspector that it continuously loads. I utilize this feature a lot to check how constraints are behaving. Was wondering if anyone else had the same issue?
Steps that I have taken to try and resolve it:
Reset all simulator data
Cleared all derived data
Cleaned build
Tried multiple simulators with the same issue
Just had the same issue. Creating a new simulator on the latest iOS that came with Xcode fixed it for me.

Xcode 9 - Safe Area Layout Guides Error Comes Back

I am making a game in SpriteKit for iOS, and I want my app to support iOS 8.0 devices. I changed my deployment target to 8.0, and suddenly I have an error:
Main.storyboard:7Ti-J4-z1q: error: Safe Area Layout Guide before iOS 9.0
So I Google how to disable them, and I uncheck the "Safe Area Layout Guide" box in all of my storyboards:
I build again, only to the same error, even though it is unchecked. I tried restarting Xcode, deleting and recreating the storyboards, but nothing seems to work!
Does anyone know how to fix this issue? Thanks!
UPDATE:
After restarting Xcode, the check box reappears checked, even after unchecking and saving.
Ok, after searching through settings, I realized that you also have to uncheck safe area layout guides under your view controller, so now I have unchecked it there and it builds successfully!

XCode colors desaturating when compiled into Simulator

The colors in my ViewControllers are all desaturating when I compile into the simulator. The same desaturation occurs when viewed on my iPhone. Within XCode itself, the colors appear fine, it's just compilation that appears to be the problem. I've been looking high and low for color settings but no luck. Has anyone run into this?
It looks like this was a bug in Xcode 7 Beta. I just upgraded and the issue was fixed.

iOS 8 app does not show all keyboard languages

I've encountered strange issue. My app running on simulator shows only English/Emoji layout for UITextField.
BUT! The spotlight shows English/Russian/Emoji, and it's correct.
I use Xcode 6.1 and iPhone 4s iOS 8 simulator.
What's wrong?
Dupe of iOS8.1 Simulator always uses US keyboard layout despite german hardware keyboard
As mentioned there, this is a known issue and is mentioned in the Xcode 6.1 release notes.
