Since Yesterday when I build and run my app I m getting build Succeeded and Finished running 'appname'on iphone simulator and then it stops running. When I reset the contents of simulator then it shows me the app.This happens to me from yesterday.Before that I used to run as many apps in my simulator.But now when I reset contents then only I can run a new app.
I dont understnd whats wrong with xcode..?
Is there a way that I don't reset content settings everytime for a new app?
Try this..
1.Manually launch the iOS Simulator.
2.From the "iOS Simulator" menu, click "Reset content and settings",
3.Close and rebuild your app.
I fixed it by doing the following..
- clearing the derived data
- resetting the simulator
- shutting down the simulator and having it be launched by xcode after that
I did figure out what it was I was doing to get into the problem. I was trying to copy a folder called Resources to the bundle. Twice doing that got me into the mess. Third time I renamed the folder to just Res and it seemed to work. Seems like "Resources" is a special name for folders in a bundle and you can't use it for your own content.
Lately when I have been deploying any iOS application to the simulator (iPad or iPhone), XCode locks up (Not Responding) and the simulator simply displays a black screen. I have to force quit both.
Steps I have taken so far towards a resolution:
Clean
Reset the Simulator
Deleted the simulator folder
Reinstalled XCode from the App Store
Reinstalled XCode from the developer center
Has anyone else encountered this? Any suggestions for a solution?
Other info:
OSX Lion 10.7.3
XCode 4.3.2

Thanks in advance for any help.
I had this problem and was able to continue by:
1) Edit the run scheme by clicking on the first part of the App name to the right of the "Stop" button to bring down the scheme list and click "Edit Scheme..."
2) Click on the Run item and change the debugger from LLDB to GDB.
3) Run
I think the problem was that I validated the settings and it offered to automatically change the debugger from GDB and LLDB and I clicked "OK" because the advisor message sounded very self-assured.
Enjoy.
Under Scheme, go to edit scheme, and change launch from wait for App.app to launch to automatically under the Info tab.
EDIT: If you upgraded Xcode, make sure the old separate simulator is uninstalled.
hmmm, weird simulator, instruments issue i had once would work when i command-tabbed back and forth. try deleting derived data?
I have this navigation app with several views and no data yet.. however I had a small break from coding over the weekend and have come back to it only to have it not load in the ios simulator.
There are no errors in the xcode output while it runs but as soon as i click to run button it loads the app up but as soon as it opens it closes and goes to the home screen.
I have tried cleaning the build and opening closing everything but just cannot figure this thing out...
Since there is no error messages or indication as to what is wrong I am going to suggest
a few other things you can try out:
Have you tried "iOS Simulator" -> "Rest content and settings".
In Xcode click the "Product" menu in the menubar, hold down the Option key and
you should see "Clean" change to "Clean Build Folder".
Lastly pull up Organizer (Shift+Command+2), select the "Projects" and the then click "Delete Derived Data".
The two last ones should not be directly related to the simulator, but they won't hurt either.
Does your app requires internet connection to run.. if it does, check ur internet connection as well.
I have this kind of problem last time and turn out, if there's no internet connection and you didn't put any exception on that, the app will straight away crash with no errors..
I used to be able to type with my real mac keyboard after launching the iPhone Simulator. Typing with the on-screen simulator keyboard is just horrible when testing with large amounts of text.
No matter what I do, I can't get my keyboard to type anymore inside the simulator. Even if I have "Simulate Hardware Keyboard" switched ON, it just won't type anything. Can someone please tell me what I'm doing wrong? Is there no way to type using the real keyboard anymore?
Try trashing the iPhone Simulator preferences file. When my iPhone Simulator stopped responding to keystrokes, this fixed it.
Quit the simulator.
Go to finder and press (command+shift+G) then navigate ~/Library/Preferences.
Move com.apple.iphonesimulator.plist to the trash.
Try launching your iPhone app in the simulator again.
Deleting com.apple.iphonesimulator.plist did not help me under Xcode 6.0.1.
Probably, it worked in old Xcode.
But, what works perfectly for me under Xcode 6.0.1, it is new hot Keys in iOS Simulator:
Shift-Command-K Connect/Disconnect Hardware Keyboard
Command-K Toggle (Show/Hide) Software Keyboard
And, you know, I really suffered for last 2 months, until found it, and it is very convenient now))
Don't trash the iPhone simulator preference files. There's no need to do this.
Look in the simulator's menu Hardware ➔ Keyboard. The menu options are:
iOS Uses Same Layout as OS X
Connect Hardware Keyboard ⇧⌘K
Toggle Software Keyboard ⌘K
Ensure option 2 is checked.
If it's already checked, uncheck it then check it again (you'll probably want to learn the keyboard shortcuts).
If you find that this hides the on screen keyboard, but you also want this to show, use option 3 to toggle it back on.
If rotating the simulator seems to stop the keyboard working, toggle option two off then back on – this seems to resolve it.
I am using iOS Simulator Version 7.0. While the simulator was running I went to iOS Simulator->Reset Contents and Settings... and reset the simulator from there. That seemed to have done the trick for me. Hope that helps.
This is because you have used changing the orientation of simulator using keyboard shortcuts. Just press cmd on the mac keyboard then start typing.
All I needed to do was quit the simulator and launch it again
MY PROBLEM WAS KEYBOARD IS SHOWING AND KEYSTROKES NOT DETECTING. AND I FOUND THE SOLUTION:
You don't need to quit the keyboard.
Try Hardware->Keyboard->Connect Hardware Keyboard directly
Removing com.apple.iphonesimulator.plist worked for me too, but I had to locate it inside the hidden folder /Users/[yourusername]/Library/Preferences/
Shell / Command-Line / Jenkins / CI:
sh "plutil -replace DevicePreferences.${deviceID}.ConnectHardwareKeyboard -bool NO $HOME/Library/Preferences/com.apple.iphonesimulator.plist"
sh "plutil -extract DevicePreferences.${deviceID} xml1 -o - $HOME/Library/Preferences/com.apple.iphonesimulator.plist"
The Device ID can be found via xcrun / simctl, based on the devoce name:
xcrun simctl list | grep ${simulatorDeviceName} | sed 's/).*(.*//;s/.*(//'
I encountered the same problem and tried a lot of different ways which worked mostly but never for sure. Ultimately, I found this. https://stackoverflow.com/a/26057011/1463604
If you are developing a React Native app and you cannot refresh (⌘R) or enable remote debugging (⌘D) from the iOS simulator, while other keyboard inputs work, make sure you are running a debug build configuration. You can check this with:
Product -> Scheme -> Edit Scheme -> Run -> Info -> Build Configuration -> Debug"
I got this tip from here.
Just restart Simulator (close and open the app).
When I first ran my app that uses CoreLocation in the iPhone simulator, I was prompted with the dialog saying that my app would like to use my current location. In that popup, there is a checkbox that says never ask again. I had that checkbox selected, and now I never receive that popup again. How can I revert this change? I'd like to see the popup again to do some testing. Thanks for your help!
Deleting the app and running it again will do it, or you can go into Settings -> General -> Reset and tap "Reset Location Warnings" (which will reset it for all apps.)
None of the above worked for me. But I found changing simulator version from 4.3 to 5.1 fixed the problem temporarily.
