Previously in XCode there has been these warning messages with yellow warning icon. Back then, I was able to run my Flutter app on iOS simulator just fine. Now that they have become red, I can't run it on iOS simulator anymore. And there's No Devices listed anymore as shown below.
Is there a way to revert the iOS configurations in Flutter to the default? Or is any better way?

When using the simulator under Xcode 11.3.1 and iPhones simulating iOS 13.3, the simulation does not behave correctly. It works correctly under simulator iOS 12.1.
I get no messages that I don't also get under the iOS 12.1 simulator launch.
The behavior should be when a user starts the app for the first time, he is redirected to the signin screen. Instead it goes to the main screen (grayed out because there is no data). I can navigate manually to the signin screen and signin normally (device registers and appears on my online server) but the app should start downloading the database required to work. It just sits there (no alertview that would normally launch the download). If I relaunch the app, it again starts at the main screen, however at this point an alertview should appear that no database is present. If I manually try to start the download (in a setup screen within the app), the progress bar that normally appears does not, just a label signifying what database is suppose to download.
All of this works properly on the iOS 12.1 simulator (Xcode 10.1) of the same type (iPhone 8 Plus).
Is this an Xcode 11.3.1 bug or iOS 13.3 problem. I have customers using iOS 13.1 without any problems on actual devices. I am on a new iMac running Catalina, is it possible its a security setting to allow database download?
I was facing the same issue and I move back to Xcode 11.3. Guess it was not a stable update at all.
I'm currently using Expo to build an iPhone app.
I'm not supporting iPad and I have it so when it builds on iPad it runs in an iPhone Simulation.
The problem is I can't develop with Expo using this approach.
The app shows up as an iPad app, but this is not the mode being shipped to users.
According to this I might have some luck adding ios.supportsTablet to the app.json file and setting it to false but it didn't change anything.
Is there another configuration value I'm missing to force iPhone simulation mode on an iPad?
I'd rather not eject if I don't have to.
According to this, there currently isn't a way to live develop using "iPhone mode" on an iPad.
The Expo Client app can’t change its tablet support on the fly,
unfortunately, so it will always adapt your project to the iPad
viewport.
So, following the above forum here is how you get around it:
Run exp build:ios -t simulator
Open Simulator
Select Hardware/Device/iOs 11.x/iPad x generation
Unpack the generated build from the first command
You should have a file named yourApp.app
Drag that file into the iPad you are running in Simulator
It will install the app on the device and you can then view your creation
This is faster than doing a whole build cycle with TestFlight just to see your changes.
But it still leaves a bit to be desired.
I've been writing an app and I've released one version to the App Store. I've updated it slightly since then and have been playing with it on the Simulator. Unfortunately the Simulator has stopped reacting to the changes in my code. I know it's the simulators fault because if I run the app on my iPad the changes take effect.
I've tried resetting the simulator by going iOS Simulator -> Reset Content and Settings, I've tried quitting the Simulator and Xcode.
I have no clue why the Simulator is not working properly. It's just blatantly not updating.
Clean your project with command+shift+K.
Quit Xcode and clean ~/Library/Developer/Xcode/DerivedData manually. Remove all of its contents.
I have multiple Xcode Apps installed in OS X 10.9.2 to check the compatibility. Now I am facing a problem when I run the app, this error occurs "iOS simulator failed to install the application". I want uninstall all Xcode completely to reinstall latest Xcode 5.1. How can I do that? Thanks.
Xcode Instances
/Applications/Xcode.app (Xcode v5.0.2)
~/Apps/Xcode.app (Xcode v4.6)
Use Appcleaner
or
Just drag and drop Xcode to trash from app folder
Looks like this is a known issue. From the -->>
https://developer.apple.com/library/ios/releasenotes/DeveloperTools/RN-Xcode/Introduction/Introduction.html
**After switching the minimum deployment target of an application from
iOS 7.0 to a release prior to iOS 7.0, building and running the
application may fail with the message “iOS Simulator failed to
install the application.
” Go to the iOS home screen, click and hold the application icon, then tap the hovering “X” button to delete the application.
**
Another release note:
iOS Simulator If an iOS app is detached, relaunching the same app
from Xcode will result in a black screen in the Simulator even though
the new app is launched. Terminate the app in the Simulator or
relaunch it for the second time.
if you have already developed project and you used xib to develop views then
X-Code > Inspector Selector Bar > Interface Builder Document > opens in > and change from Xcode Default(5.o) to Xcode 4.6 .
Build and Run your app it will run successfully, if it won't run again then, header over to iOS Simulator - Reset Content and Settings. delete old app from simulator then Run again.
when i run the XCODE with ios 4.3 the default simulator is set to ipad ....I changed active executable setting to iphone simulator .. but stil its not working ..Whenever i open the XCODE again its restting back to ipad .. Is ther any other way to set this out ?
When building the app in the iPhone simulator, wait until the iPad finishes loading; if your app is displayed and working properly then (and only then) try switching to the iPhone simulator.
To keep the iPhone display as the default, try changing the program preferences from the simulator itself or from the Xcode project file in Xcode.
