Running the app on the simulator shows: "Unable to boot the iOS simulator" - objective-c

Running the app on the simulator shows: "Unable to boot the iOS simulator". I'm on Xcode 6.0.1.
I tried everything: resetting the simulator; selecting the Xcode 6.0.1 command line tools; restarting the Mac. The problem is still present.

Try this. In Xcode menu: Open Developer Tool > iOS Simulator. When it opens, use the menu to go to Hardware > Device > Manage Devices.... In that list, delete the non-working simulators and re-add them.
Also make sure that the Downloads section of Xcode preferences is up to date.

Do you have DYLD_INSERT_LIBRARIES set? If so, this is a dupe of:
Unable to boot iOS 8 Simulator
Check /etc/launchd.conf

I have new installed Xcode 8.3 with iOS 10.3.
My application ran on iOS as expected and suddenly Xcode fails to run application on device with error:
Could not launch "My app" process launch failed: unspecified
It runs on Simulators and on other device mini-pad (10.2)
I also have this problem when run in iOS 10.3.1 with xcode 8.3.2
Restart device, It will work well
I tried plugging out-in the cable of iOS - doesn't help
I restarted iOS device and Xcode - everything works as expected
(hope it will help to someone)
Plugged out the device cable.
delete App.
restart device.
Delete Xcode Derive Data
Quit and launch Xcode again.
Build and run successfully.
I had similar issue. Tried below steps :
Quit Xcode (cmd + Q)
Clean project (cmd + shift +k)
Delete Derived data (cmd + comma)
But these didn’t worked. Instead restarting device worked!

unable to connect ios 9.1 device to xcode 7.1

I am trying to run application in a device with iOS 9.1 from xcode 7.1. xcode is keep crashing. I am unable to install the application in any ios 9.1 devices. I have tried 3 different devices and getting the same problem. My code is in objective-c.
I have uninstalled the xcode and then installed xcode 7.2 again. It solved my issue.
I think you should do something for fix it, maybe it's just some stupid errors from xcode.
Try to clean then build again.
Add a devices for development then test again.
Report to Apple.
Check your iOS Target Deployment first.
Also try following steps
Also try reinstalling Xcode 7 and while installing close Xcode.
Check in Xcode Preferences whether Simulator for iOS9 is installed or not.
also check whether your itunes open when plugin device.

iOS Simulator Doesn't Install Application

Using Xcode 5.1 to debug an iOS 7.1 iPad application.
When I build and run my project in the iOS Simulator, the simulator opens and my app icon pops up for a second. Then it looks like the app stops installing and the simulator goes to the home screen. Xcode still thinks it's debugging and it doesn't show any errors in Xcode or the simulator. I can go to my app in the simulator and click it again, but it just crashes. I get the same behavior in iPad, iPad Retina, and iPad Retina (64 bit). Any subsequent tries to run the app in the simulator doesn't even attempt to pop the app icon up until I quit the iOS Simulator and try again. All the usual fixes haven't worked for me yet.
Fixes I've Tried:
1. iOS Simulator > Reset Content and Settings...
2. Window(in Xcode) > Organizer > Delete Derived Data & Delete Snapshots
3. Delete Contents in ~/Library/Application Support/iPhone Simulator
4. Uninstall Xcode and reinstall
5. Clean project and rebuild
6. Restart machine
I'm out of ideas. Is there something I've missed?
Thanks all!
Create another app with the exact same template and look at the app delegates and make sure they are the same.
Example: AppDelegate.h and AppDelegate.m
You might've accidentally deleted an area that helps load the App.
Alright I found the problem. I was playing with how we load our frameworks because we were having other issues before and I left a bad value in our Linking settings.
Here's how I fixed it:
Project > Build Settings > Linking > Mach-O Type set to "Executable"
It was set to "Bundles" before which causes Xcode to package the app in a way that caused ours to break.
Helpful Post: In Xcode project target build settings, What is Mach-O Type?

xcode 5 issue : "iOS Simulator failed to install the application"

I have just upgraded my xcode version to 5.0. After running application 2-3 times it's giving me error like this "iOS Simulator failed to install the application". This is working fine in old xcode. When I reset the simulator it works fine, but this is irritating again and again.
Can anybody tell me what is the real issue? How can i resolve it.
Did you find new solution for this thing?
Try manually launch the iOS Simulator and from the "iOS Simulator" menu, click "Reset content and settings", then close and rebuild your app. It worked for me.
i got the same problem but solved by following way....
launch the iOS Simulator
Go and click "iOS Simulator" Menu
click "Reset content and settings"
close simulator and rebuild your app.
Above screen shot is showing the way how you can do this...
I think this works for you...!!!
I just used CMD+SHFT+K and quit the simutor and then run again and it's working, no need to reset simulator or delete an applicaiton.I'm not sure but some time it will work.
Just delete the application from the simulator and build it again.
Or try to use a device with different iOS version.

How to simulate iPhone 5 in Titanium Studio?

I am trying to run the iPhone emulator to emulate iPhone 5.
I ran the application Run as > iPhone Simulator and tried to change the device as shown below
But when i run the simulator it still shows iPhone 4 simulator, what am i doing wrong?
I got the answer..
For some reason, we could not set the Hardware > Device to iPhone(Retina 4-inch)
when running from Titanium Studio.
You create a new sample project in XCode and run the emulator from there and select
iPhone(Retina 4-inch) from Hardware > Device menu when the emulator shows up.
Close the emulator and run the iPhone simulator from Titanium Studio, now you will be
seeing iPhone 5 simulator.
You should change the run configuration of Simulator.
You need to open the iPhone simulator outside of titanium. There is not need for an application to use, just open the simulator.
The simulator can be found here:
Applications > xCode (show package contents) > Contents > Developer > Platforms > iPhone Simulator > Developer > Applications > iOS Simulator.
Open this application, and select the hardware of choosing through Hardware > Device
After that, close the simulator, and launch the app through Titanium as usual.
Just open xcode (Welocome screen is enough, no need for empty project). Then in main menu open: Xcode > Open Developer Tool > iOS Simulator
Then in simulator open in main menu: Hardware > Device > ...select device...
Go back to Titanium Studio and run application again.
The best way to do this is to go to "Run Configurations" in Titanium Studio and then change "Display Type" to Retina.
