I had an old app icon in xcode that I had just attached to the program to see how it looked in the simulator. I made changes, deleted the images, and replaced them in Xcode. However, they are still the old ones in the simulator. I tried resetting it and everything. Does it keep a cache somewhere?
EDIT: Solved by cleaning project.
Have you tried cleaning?
From the Xcode "Product" menu, choose "Clean" or "Clean Build Folder" if you hold alt/option.
If "Clean" does not work, try this:
Reboot the device
Kill the app before running it from Xcode.
Those works in my case.

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.
In xcode, I tried to add a tap gesture to my app and when I built it, it started a problem with Xcode. It goes from building, 'running on iPhone 6.1 simulator' to 'finished running on iPhone 6.1 simulator'.
If the simulator is closed, it starts up with a black screen and you cannot click the home button etc. If open, nothing happens, the app doesn't install but the simulator doesn't crash.
I have tried the armv6 architecture 'fix' but that didn't work. I have also cleaned the project and project data. I have reset the simulator multiple times as well.
If I add the old files to my new project, it works up to a point (I copy and paste old files into new) but then the same happens.
Thanks for your help in advance!
NOTE:
New blank projects build and run fine.
EDIT: It still didn't work after undoing my previous actions, and the simulator is responding according to Finder, although the screen stays black

UPDATE
I had a folder named 'resources' in my application, imported as a reference which, following links from the thread #arthan.v supplied me with fixed the problem. What I did was rename the folder to files and reimport it.
Thank you so much, I spent 2 days trying to fix it before now!
Click the Center Button in View on your right hand side of Xcode.
In your Bottom bar, you'll see error: failed to attach to process ID 0.
Check these error: failed to attach to process ID 0 and Xcode compiles my App, but can't run it in the simulator
This sometimes gets fixed by these steps:
iOS Simulator > Reset Content and Settings ... > Reset
Xcode > Build and Run
I experienced the same issue after I had re-organized some code and renamed the workspace and project. Eventually realized there was an old version of my test app on the simulator's homescreen. I delete that and then everything was building fine again.
You might need to add the device to the provisioning profile. I experienced this on Xcode 6 and a real device.
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 a strange app behavior: The App updates the GUI changes only after returning from the background to foreground. When launching, some GUI elements are also missing and appearing not until returning from background state. Any touch on buttons fires not until going to background and reentering foreground.
The problem is with iPhone, iPad and both simulators and with Xcode 5.2.1 up to 5.3. It appeared after deleting the app from the devices and resetting the simulator. Beforehand there was never a problem like this with this app.
When you can't fix it, restore it: With version control i reverted the AppName.xcodeproj directory (Finder shows it like a file) and it fixed the problem.
Then Xcode offered me to "upgrade to latest recommended settings and perform project clean up" which "removes unnecessary build files". I did that and also chose the "create snapshot option". After that i had the same problem again.
The i reverted to that snapshot before the project settings update and it worked again.
Key take-away: "upgrading project to latest recommended settings" can have nasty side effects. Snapshots and version control are great stuff.
Further investigation showed that in Settings.bundle one missing Root.plist file was reason enough to kill my GUI. I had there Root~ipad.plist and Root–iphone.plist and thought the Root.plist is no longer needed. Looks like you need all three if you want separate plists for iPhone and iPad.
In my project summary, I dropped an image in Launch Images place. Which started shown as splash screen when application starts.
Now I have deleted it and there is no Default.png in my project folder. But still that image is being shown as splash screen.
How I can remove it?
Any idea .... ?
Have you tried doing a clean build?
or deleting the app from the device/simulator and re-deploying it?
Most likely, all you need do is clean the project, then rebuild.
To clean the project, simply press cmd+shift+K. Then, build as normal.
To illoGicalError
doing clean and Build will not remove it.
You need to delete the application on your simulator ,then run your application again... It will work...
Press Command+K then build and run. This will remove all unused images from your build.
You can also get to this command from the project menu bar
Try deleting the .app from the Products folder in your Xcode sidebar.
But generally, don't worry - Xcode just likes to cache things like this - if you build for the device then it won't be there.
