"No Bundle Url Present" Error on running react native app on real ios device

My App was running quiet well on my iPhone XR when i connected it to my mac. things started going wrong when i upgraded my iPhone software to 15 from 14.
after the upgrade, xcode started showing "iPhone is not ready for development" as soon as build process completed. i found it was an issue due to xcode & device ios version mismatch. Hence i upgraded my xcode version to 13.3 from 13.1
Now when i build the app on my iPhone, the build gets successful, it installs the app on my device, it opens up automatically but fails to load from bundler running on my system, showing error in the screenshot attached.
hitting "r" on bundler terminal console also shows "no apps are connected"
enter image description here
the app runs quite well on ios Simulator though, i dont encounter this error while running on simulator

React Native iOS Debugging in Safari Missing on M1

I'm used to debugging my React Native (0.63.2) app using Safari's dev tools. I got an M1 Mac Mini last week and have since been unable to get the console or source tabs to show anything from the iOS simulator. Not sure if this is related to the new machine, or if I missed a setting. Any ideas?
I usually do Develop > Simulator > JSContents from Safari, and everything would show up fine. I can get logs in the terminal, but Safari's devtools are much easier to manage.
Installing and using the "Safari Technology Preview" from https://developer.apple.com/safari/download/ worked for me.

Expo project android emulator issue

I've been working on a react-native app managed mode built on expo, I was working from a mac at first which worked perfectly fine using the IOS simulator it didn't work on android emulator on mac, here i switched to a windows computer and the issue still exists on the android emulator, executing the command "expo start" the app crashes after the splash screen before the logo appears, I tested the app on a real device on the debug mode and it worked! also after deploying the apk file the app works with no issues, the only problem is it's not working on android simulator using expo client, things i tried to solve the issue including trying to reinstall android studio and install the latest version, tried updating expo sdk to latest version also tried playing around with the app.js from where the app launches the first time but still crashes at the same point, it's not showing any errors or warning it just crashes, any suggestion or something i could try would be very helpful thanks.
I am also having a similar issue : after upgrading to the latest release (SDK 41) the android simulator hangs often and the app crash without any errors. But works some time .

Is It Possible to Build and Distribute Simulator builds in AppCenter?

Our Automation QA team require a simulator build of the test app. Getting below error while building:
Is It Possible to Build and Distribute Simulator builds in AppCenter?
I have contacted Appcenter's Helpdesk. Following is their response :
You can build and distribute apps in App Center that can run on simulators and also on real devices.
For Android, if the build has been correctly signed, the APK can be installed on a real device and deployed to the Play Store. If the build has not been signed, the APK can be run on an emulator.
For iOS simulator, it is required for you to properly code sign the app. You can learn more about code signing for iOS here: https://learn.microsoft.com/en-us/appcenter/build/ios/code-signing
Then please see the steps below to set up code signing when building your app in App Center:
To sign the builds produced from a branch, enable code signing in the configuration pane and upload a provisioning profile (.mobileprovision) and a valid certificate (.p12), along with the password for the certificate.
Download the ipa file to install on a simulator.

Xcode 7.3 - Unable to fix code signing issue

I am new to this Xcode and we are using 7.3 version. We had a problem in launching the app on iOS device with the Xcode after connecting my Mac to the iOS device (iPad).
I have connected my iPad to Mac and then build the solution but I have been encountered with an error message along with Fix issue button in the warning message.
If I clicked the Fix issue button then I am getting the error as:
Unable to fix code signing issue. Xcode failed to resolve the issue. Check your code signing settings, ensure you have a matching signing certificate and provisioning profile installed; and try again
Because of this error I could not be able to run the app on my iPad device. Can you provide me a solution on how to fix this issue and make the app run in my iPad device?
