I have an app which is currently published, this one person reported a problem with an iPhone 7 iOS 13.5.1 where he could not use it, basically the background of a table view cell is completely black where on all other devices is white, because of that and since the text is black, this person can't read anything. Also in the search field he can't see what is being typed, there, the background is white and the text which is supposed to be black is white. We actually got a screenshot which is by the way not very clear but you can see a faded version of the text in both the search field and the table view.
We also have the same model and with the same OS version installed but are not seeing the issue, for now we have only gotten report from this one person.
Has anyone experienced a similar issue that can point me to what the problem maybe?
You need to set your background color to white instead default.
"default" will set your background color in black if the device is in dark mode.
This looks to be an issue where your user has dark mode enabled, but your app appears to use a mixture of hardcoded and semantic colors.
As a quick workaround your can force your app to always use light mode by adding
<key>UIUserInterfaceStyle</key>
<string>Light</string>
to your Info.plist

Just updated to Xcode 13 and Visualstudio Mac to 8.10.10. Since then my app:
Wont display the splash screen.
The app is cropped at top and bottom.
Ui is acting generally weird.
Now I have read old threads on similar problems and adding the Launch screen interface file base name. in the info.plist file does make the app cover the whole screen.
I have tried switching splash screens and change location. But it's just black. I don't use a storyboard for the splash and instead provide several different resolutions, which have worked fine for several years.
The UI is glitching like the loader picture, and several different ui elements where colors are provided are "cut" in the middle showing two colors when it should switch.
I have read the release notes for xcode13 but haven't found anything related that would break the whole UI.
The interface glitching and no splash screen I can't seem to find a solution for. Everything worked fine before the update.
What could be the problem? Some setting in the info.plist, a checkbox in the storyboard?
I'm still new to Xamarin and iOS development and greatly accept suggestions.
Let me know if I can clarify anything.
Thanks

According to your statement, you are not using a storyboard, so you need to replace the Launch Screen with a LaunchImage, then check the LaunchImage file (if it does not exist, you need to create it yourself) and add all strictly standardized pictures inside.
I've updated my iOS app to work in dark mode on iOS 13 but I am having trouble trying to get the launch screen to look good.
Currently it is a bright white screen with the app logo which looks awful in dark mode. I have tried setting the background colour of the launch screen to be a colour asset that I made with "Any Appearance" being white and "Dark Appearance" being black - but the launch screen still always shows as white.
Is there any way to get my launch screen to work properly in dark mode?
When setting up the Launch Screen storyboard, set the view "Background" color to "System Background Color". This will be white in light mode and black in dark mode. No need to use your own color asset.
I found a solution that supports earlier iOS versions as well as custom colors for each mode, dark and light, in iOS 13.
Create an image asset, set Appearances to Any, Light, Dark, and load small solid pngs with your desired colors. In this case I am using orange for light, and black for dark.
Go to your LanuchScreen.storyboard and add an image view with that image asset. Place the image behind your image logo, set Content Mode as Aspect Fill, and constrain the view to the Superview in all sides. (Make sure that your logo looks good with the two backgrounds, or set its Appearance too)
This is where I had to do a trick. For some reason, I couldn't make the back image to show up. After checking some of the comments in Launch Screen storyboard not displaying image, I added the first image in the image asset to the target bundle
The color is static in older versions of iOS, and it works well with dark and light modes in iOS 13.
I was updating my app to support new Dark Mode for iOS 13, I put "System Background Color" for the View's background in my LanuchScreen.storyboard, but surprisingly it didn't work!
The Logo image on the page was changing correctly based on Light/Dark Mode, but not the background!
I was about to apply Jose's solution, but before that, I decided to completely remove the app from my device and try again. And it worked!!
I was missing colors from my color palette in Xcode defaulty offered colors so I created my own using Color.xcassets where I created custom color set with appearences Any, Dark and set my colors.
Then I can use them in autolayout same like System Colors even in LaunchScreen
Yes Launch Screen work in dark mode, First check the background colour of your "xyz" image. if it is ok. just delete you app from device or simulator, because some time Launch Screen cached by device or simulator and you will not get the update UI on it. if you will face same problem just follow my demo app github.com/Indolia/darkmode.git
I am having this strange problem. I have added icons of sizes 120*120, 58*58, 80*80. This is what I usually add as icon for all my iPhone apps. And there is no rounded corner in the design. But, when i run the app on iPhone4(IOS7), the icon shows a strange black line on all four edges(not on the rounded corners). I have cross checked the dimensions and confirmed it is all ok. I even tried migrating my app to asset catalogues, tried hard reseting the device but nothing helped. Then I tried running the same app on an iPad(running IOS8) and I found a similar issue, just that the lines now appear on two sides, not all. All other icons are ok. The problem just happens for this one app. Can anyone tell me what might be the probable issue and how to resolve it?
The icons might have transparent edges. Remove the transparent edges.
In my case, it was a drop shadow attached to the icon which came along with the export. Sometimes designers add this drop shadow effect so you can better visualize the icon when designing, but if you add this to your app, you will get thin black lines around the app icon.
What does the red dot (circle) next to the app name below the app icon mean?
I added a Today Extension (Widget) to the app. It appears only when I launch the app on the iOS 8, it does not appear on iOS 7 simulator. Even though I removed the extension and cleared the simulator, it still appears before the app name.
An Orange dot next to an app normally means it's a beta version, as installed through Testflight. I have a couple of those at the moment, though one looks more red. Trying to find if there's a difference between an orange and a red dot, or if it's just an artefact of the colour of the background image that makes it look red.
The dot you see is actually an orange dot, with transparency. On dark backgrounds it seems like it's red. Try changing to a bright background.
Orange dots for all beta apps that are downloaded from TestFlight and blue dots for recently updated apps from App Store.
Thanks for the question #user5673323221, and the answer by #PhilBowman. As apart from the red colour, there are few more colours as well such as yellow and blue having their specific meaning.

I have been trying to solve this app icon color issue all morning. I am still experiencing this after going through both of these highly recommended photoshop/iOS design articles:
http://davidmckinney.com/blog/2013/12/31/designing-iphone-apps-how-to-setup-photoshop
http://bjango.com/articles/photoshop/
Here is the problem that I am having:
When creating my app's icon, the color that I see in Photoshop is the exact same color that I see in xcode's asset catalog. It is also perfect when I run the app on the iOS simulator.
However, when I run my app on my iPhone the app icon's color is always darker.
What's weird, is if I take a screenshot of my iPhone's screen and email it to myself, the color is correct! So for some reason the color is only darker when you are actually looking at the iPhone's screen.
Pardon my ignorance, but this is the first design I have ever done for an iOS app and I don't understand why this is happening or how to fix it.
EDIT: I am now using LiveView after reading this answer: https://stackoverflow.com/a/3597221/3344977
What's funny is no matter how hard I try I cannot get the color I see on my screen to appear on my iPhone screen. It's as if this shade of Pink I'm trying to use just isn't possible to render on an iPhone display.
This is because your iPhone and Monitor screens have different color calibrations (if that's the right term)
You're going to want to setup a color profile on your computer that matches the iPhone screens as closely as possible, and use that when developing icons.
for some reason the color is only darker when you are actually looking at the iPhone's screen
Consider turning up the brightness on your iPhone. Go to Settings->Wallpapers & Brightness to adjust it.
In any case, the issue isn't that the value of the color is changing on your device, it's just that that color value is being rendered differently.
Its because the resolution of your screen is different than your iOS device try it on other device
