I am trying to run my app in simulator it start deploying in visual studio but not launching on simulator.
even if I manually open that simulator app doesn't runs over there.while is shows running in vs
please help if anyone have idea whats going wrong here
Make sure you have Xcode installed in your mac. Make sure Xcode is running in your mac. If you are using vs from windows make sure you are on the same network with the mac, and you are connected to it. You can always try to change the simulator in which you deploy it. Also check the simulator if the app you want to run is installing in the simulator. You should wait until it's installed to run your app. I hope it helps this time. :)
it was due to memory issue of mac.
mac memory was full so it was unable to launch simulator.as i have cleared memory and make more free space it start ruining now.
thank you everyone.

Annoying problem here for my Flutter app: iOS13.3, Xcode11.3 on a physical iPhoneX. The iOS-Simulators all work. The problem is only happening on a physical device. The Flutter App freezes at startup (i.e. at Installing and Launching... step) ! Any ideas ??
My flutter doctor -v does not bring any problems. Also tried flutter clean and flutter upgrade. But nothing seems to fix the problem...
If I run the App from Xcode (Runner.xcworkspace) then everything works as well. Only from VSCode and Flutter, I can no longer launch my physical iPhoneX.
Also, when uploaded to TestFlight, the App freezes at App Start ! (grey screen freeze). Therefore Apple App Store rejects all Flutter Apps for now ! Very annoying.
I am not sure if the Installing and Launching... freeze is related to the TestFlight and App Store Problem !! Might as well be...
This fixed the issue for me:
Run the app from Xcode.
Disable WiFi on iPhone.
Run from Android Studio.
Turn on WiFi on iPhone once the launch process has completed.
This is a workaround solution
I was having this issue. I uninstalled the app from my device, opened the project in xcode, ran some build cleaning thing that appeared in the yellow triangle warning area, then built the app via xcode. Then uninstalled the app from device again. Then ran via android studio and it worked.
Basically, it is because of might some files
For me, this worked
Follows these steps: Go to Flutter > bin > cache
and delete the Artifact folder
Try executing the command: killall -9 dart and retry.
As in my case, I use one of following solutions to fix the issue:
#1. close WiFi on mac, then run from Android Studio; OR
#2. close WiFi on both mac and iphone, then run from Android Studio; OR
#3. enable hotspot on iphone and connect it from mac, then run from Android Studio;
Xcode 9.2 debugging on an iOS Simulator has completely broken for me.
I worked on this for hours and tried a ton of suggestions short of completely wiping my hard drive and starting out with a fresh operating system install. I ended up filing a bug with Apple. Posting here in case anyone has encountered this problem and has any suggestions.
Summary:
When try to build and run in debug mode with a debug executable. The simulator only opens the application to a white screen and then Xcode pops up an error:
Could not attach to pid: "<a process id>"
Ensure "<app>" is not already running, and "<user>" has permission to debug it.
Steps to Reproduce:
Make any project and try to run on any simulator.
Expected Results:
Debugger successfully attaches to debugger.
Actual Results:
Debugger is never able to attach to the iOS simulator process/app for debugging.
Debugger CAN attach and build and run successfully on a physical device.
Version/Build:
- Xcode Version 9.2 (9C40b)
- macOS Sierra 10.12.6
- Any iOS project
- Any iOS simulator
Other notes:
- Xcode 9.2 was working fine until this problem randomly started. The error initially said:
Failed to initiate service connection to simulator
DTServiceHubClient failed to bless service hub for
simulator iPhone 8 Plus <simulator identifier>
- After rebooting computer, the error shifted to "Could not attached to pid..."
I tried dozens of suggested solutions short of completely wiping my computer including:
Resetting device contents and settings on simulators
Create a new device (even different device and OS combinations)
Try different Xcode projects, even simple one-off single view applications
Looking at the etc/hosts file and verifying localhost can be pinged
Restarting computer multiple times
Deleting out derived data (multiple times)
Let it build and run without attaching debugger, then try to attach debugger by "attach to process id"
Completely uninstalling Xcode and all simulators, and reinstalling.
Removing any invalid certificates in keychain
It turns out our security software was blocking the debugger. Running sudo sysdiagnose helped me find a log entry showing that it was being blocked. The software is Cb Defense (Carbon Black Defense). Apparently the only workaround is for your security team to whitelist by a hash, and that hash could change in the future.
There is a bug in Xcode 9.0-9.2 that causes this issue to appear after running for a while. If you log out and back in it should resolve it for you.
I am getting the following error when trying to run Visual Studio/Xamarin built application on the IOS Simulator.
Launch failed. The app 'App2' could not be launched on 'iPhone 7 Plus iOS 10.1'. Please check the logs for more details.
"App2" was created using the Tab Template, and NO code changes after rolling the application.
Windows environment: Windows 10 w/Visual Studio 2015 update 2
Mac environment: IMac Sierra fully patched. XCode 8.1 (what ever is most up to date).
I have connected the mac remote and pc. I can launch the iPhone simulator on the mac from Visual studio on the PC.
I get the error when trying to run "App2". It compiles fine, just won't run on the simulator.
I've searched here, and similar results speak of VS Crashing. Mine doesn't crash, just presents the error. NOTE: There's nothing in any log I can find with details by the way.
Ideas? Thanks!
EDIT: Just loaded up Parallels on the IMac and ran Win 10/VStudio. I get the same error. Again, xamarin remote agent connected and I can start the simulator from the PC, i just can't deploy to it.
After all the research and help from those here it comes down to a bug with the current version of Xamarin. Options are to wait until a new stable build is on the Xamarin site or get builds off of GIT. I'm choosing to wait, as I've not had great luck working with interim builds.
Xamarin that downloads with the new VS 2017 fixes this bug.
Am trying to run appium tool for testing apps. While starting appium server i finished all setting right way. When appium running the app will start at time but suddently it get crash.
Yes.Am using Xcode 6.0 and Appium 1.3.4
Make sure the .app file you are using is build for simulator if you are running appium for simulator and a different build i.e the build for device if you want to run it into real device....This is one of the cause which causes the instruments to crash at start up.
When I create an new project with XCode then generate the app file, it is working fine - I can open the inspector.
But I have a problem when I use an already developed application and the build is coming from a developer profile : I can't open the inspector and instruments crash on startup.
While running the script please start xcode and go in the settings of the mobile device and find developer options. Make sure UIAutomation is enabled there. If it is not then enable it and after it try to run the script again. Surely it will work.
I'm setting up my CI server with Jenkins. I can successfully build the app but now I need a way to run it in the simulator. How can I do it?
Have you checked out WaxSim? It's a command-line app to run the simulator. I've heard various noises about it not working on Mac OSX 10.8 but they may have fixed this now.

ios-sim (https://github.com/phonegap/ios-sim) works fine. Just be sure to build the debug version of the app otherwise it will go in background after the being deployed.
