I am changing the current product name of my iOS application in xcode to a new name by navigating to target build settings and then change the product name.
However, when I run the project after changing the product name the emulator shows a black window and the project is not loading.
Where am I wrong ? I haven't done any backup and I think the project is lost or something is not loading.. did someone ran in the same issue or know whats not turning right ?
You need to clean and reset the simulator.
For reset the simulator follow the steps below.
just open the simulator.
Then click on iOS Simulator > Reset Content and Settings ...
This will bring the popup window showin the warning about resetting the simulator and ask for your conformation.
just click on reset button.
And Done.

When I try to create new project in Xcode 8,simulators are not showing up which are already downloaded in previous project.
Click on the name of your project (which is on the right hand side of the Run button). Three options will appear.
Edit scheme
New scheme
Manage scheme
You can click on "New scheme" and then click on "OK" in popup window.
You will get the simulators back. Cheers.
I hope this works for you.
Previously simulators downloaded are of version 9.3 and deployment target is set to 10.0.Now I set deployment target to 9.3 and simulators are visible now.
Today in the morning I tried to compile my project to run in my device and I found the destination toolbar disappeared and I cannot choose my IOS device or IOS Simulator device as target. (I can do it in the Product/Destination Menu)
After some research I found the >> at the right on the screen and when I pushed a Scheme option appeared but it is disabled and I can't enable again.
This is what I tried with no success:
Open an old project to see if the problem was in my project
Create a new project (with Swift and Objective C but I don't think this make any difference)
Restart my computer
Hide and show the toolbar (View menu/Hide Toolbar and the View menu/Show Toolbar)
I tried all the previous options with the device connected and disconnected
I have installed the IOS Simulator 8.4 (when I run my project it runs in the last selected simulator) and XCode 6.4.
Looks like Xcode hides that menu when the window is a certain size. I have to make my window quite large before it comes back.
Not a fix as such but you can work around it using the menus: Product > Scheme and Product > Destination
You're probably running into the same issue I am. Like #BrandonWilliams said in his answer, it appears again if the Xcode window is wide enough. The underlying cause, for me at least, seems to be that in this build of Xcode (6.4) running on El Capitan beta 2 (with Xcode 7 beta installed), I am seeing duplicate simulators for iOS 8.4. And since there are two of the same version, the Schemes dropdown shows some sort of long GUID next to each one, causing the Scheme dropdown to be quite large:
I came to SO looking for an answer but realized that I had seen this issue before.
So the problem is basically that auto layout sucks (I mean it is not working properly in Xcode 6) and on El Capitan, the destination toolbar is for some reason hiding instead of collapsing properly. So when your Xcode window is narrow, the destination toolbar disappears.
But, if you expand the window far enough, it shows back up again.
In case you can't tell, in the first screenshot, the window is about 1241 pixels wide and in the second screenshot the window is 1541 pixels wide.
Go to Product then Destination and choose at which simulator or device you want to test your build.
I'm running with same problem. You can select device or change scheme using below steps:
Select Product from menu
Select Scheme or Destination
Select required Scheme option or Destination option
Alternative Solution:
The only solution is to use Xcode 7 or above. I've installed Xcode 7.1 and found Scheme/Simulator list available. Refer screenshot.
It seems that Xcode 6 or below doesn't support OS X El Capitan.
I am still seeing this problem in Xcode 7.2 on iMac with resolution 1920x1080. Resizing the XCode windows dens't help. I can have the menu bar back if I push the green button and go to full screen mode. But that's pretty annoying. This is how I finally figure out a solution that works for me. I notice that only if I open the project file that I have been working daily that the menu bar is missing. If I create a new project, the menu bar is there. And here is my solution:
Remove your project file on disc (or move it to a different folder)
Open the Welcome to Xcode window by shift+command+1
Make sure your project is no longer under this list. If it is still there, click on it and Xcode will tell you the project is not found and it will be removed.
Add the project file back and open it and I have my menu bar back (if you have moved it, simply opening it from a different file location may work I guess)
I guess the problem is that some cache value in Xcode about the project file is messed up somehow. Hope this helps.
I make my XCode screen little big and now find both options.
On XCode 9.0 beta, this worked for me: select View -> Show Toolbar from menu
right click on title bar -> select show toolbar
Fixed it by deleting the following file ~/Library/Preferences/com.apple.dt.Xcode.plist and restarting Xcode.
The downside is that Xcode preferences dropped to defaults obviously.
I sometimes get a dialog in Xcode which states "Simulator in use." Restarting Xcode didn't help.
I have no Simulator Icon in the Taskbar to quit it and I have no running Simulator.
Is there any solution without rebooting?
I know some of these points to not adress your specific issue since you wrote restarting Xcode would not help you but I'll try to provide a full list of possible fixes for people who might stumble upon this one day.
Is the "Stop" Button in the left corner of Xcode still clickable ? ==> Click It
Try to reset contents & settings of iOS Simulator
Clean Build & Clean Project
Quit iOS Simulator (look at the Activity Monitor if there is still something running)
Restart Xcode
Restart Mac
This is all I can think of. For me most of the times I can resolve it by just restarting Xcode. As you wrote this does not work for you so maybe some of the other points of my list will help you.
Normally this happens when you terminate the iOS Simulator but not the debug session itself, which is why most of the times the "Stop" button in the left corner is clickable most of the times...
This dialog (and the state that triggers it) comes entirely from Xcode and not the simulator itself. This dialog will present itself if Xcode is already using the simulator from another workspace. For example, if you have three projects open at the same time and you do a Build&Run (eg: click "play") in one of them, you will get this dialog if you do a Build&Run in one of the other projects.
Using Xcode 5 GM, anytime I switch to the 5.1, 6.0 or 6.1 simulators to test, I get the error "iOS Simulator failed to install application." When I reset the simulator it works, but this is getting very tiring.
Anybody have a permanent fix or workaround?
Looks like this is a known issue. From the Xcode 5 release notes:
After switching the minimum deployment target of an application from
iOS 7.0 to a release prior to iOS 7.0, building and running the
application may fail with the message “iOS Simulator failed to install
the application.”
Go to the iOS home screen, click and hold the application icon, then tap the hovering “X” button to delete the application. 13917023
Another release note:
iOS Simulator
If an iOS app is detached, relaunching the same app from Xcode will
result in a black screen in the Simulator even though the new app is
launched. Terminate the app in the Simulator or relaunch it for the
second time. 14648784
Delete the old version app in your simulator (usually iOS 6.x).
Alternatively, header over to iOS Simulator - Reset Content and Settings.
This can be easier when you have a lot of apps on the simulator and can't remember which one you're currently working on.
You need to do this for every iOS Simulator version that causes the problem.
None of the other suggestions worked for me. However, after comparing my existing app settings to a new vanilla project, I noticed that the "Build" field for my Target was blank. Once I put something in that field, the app installed just fine!
if you have already developed project and you used xib to develop views then
X-Code > Inspector Selector Bar > Interface Builder Document > opens in > and change from Xcode Default(5.o) to Xcode 4.6 .
Build and Run your app it will run successfully, if it won't run again then, header over to iOS Simulator - Reset Content and Settings. delete old app from simulator then Run again.
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...!!!
Deleting the app in the simulator works for me.
just wanted to add that this happen only if I open xib that created in xcode 4.6
If it's other files, this not happen
try this ....
in my case nothing have worked for me , after resetting the content simulator also , i am not able to install the app on simulator . after that i just changed my project location . i just moved the project to other location . then it installed successfully.
None of the above things worked for me. I just reinstalled xcode and it worked.
Ran into this issue today. Found it was an empty Reference Folder (blue folder) causing this. Removed the folder from Resources in Build Phase... cleaned build folder for the heck of it, and it went away.
/Users/YOURUSERNAME/Library/Developer/Xcode/ --> remove all contents of this folder, then simply launch the app from Xcode.
To check your Executable file settng ex.$(EXECUTABLE_NAME)
(Project setting - info property page)
I have different issue when getting error message “iOS Simulator failed to install application”, the reason is because I have added a property in App-Info.plist without any value. For instance, [Application Category] with no value. Thus the error will show up as well.
When I got this error, the image of the phone actually appeared, but the image of the app I wanted to test did not. Instead, I was on the main page of the phone that shows the apps you have. I fixed this problem by deleting the many icons that appeared on the start screens - about 30 of them. These had been created when I testing apps over the months. So, not saying its a solution, but it started working after I deleted the old app images.
For me it was -framework XCTest.
It made the app die with iOS Simulator failed to install application
and on the device Could not inspect the application package.
Removed it and now works.
You are using Xcode GM which is under beta stage. Use latest Xcode 5.1.1 available.
Also, these error occur while switching between simulator (32 bit and 64 bit).
Quit the simulator and re-build the application. OR
Reset simulator from "iOS simulator" -> "Reset content and settings.."
I changed my app name and bundle id midway. I happened to delete the Executable File name in my plist. I changed it back to "${EXECUTABLE_NAME}" (no quotes) and I'm back in business.
Does any one know why the location indicator stay on for certain bundle identifer vs. the others?
I am using an Apple sample LocateMe app, installed on my iOS device running version 5.0.1. When I'm using an old bundle identifier, the location indicator stays on the status bar, after the CLLocationManager stopUpdatingLocation is being call.
But, when I'm using the same exact app, with the only difference being a new bundle id, the app works as expected and the location indicator disappear once the stopUpdatingLocation is being called.
Did anyone experience this problem or can explain it?
I finally figured that if I reset the Location Warnings from the Settings, the bug disappear.
From your iOS Settings select General | Reset | Reset Location Warnings. This will reset the warning to all the apps. This mean that the next time you start an app that requires location, the iOS will prompt you with the location permission dialog.
Select 'Reset Warnings' from the action sheet.
When running the app again, the iOS will prompts you with the location permission dialog (if it doesn't - repeat the process above to reset the location warnings). After selecting yes, the app behaves as expected, and the location indicator disappears after few seconds.
Did you try to also stopMonitoringSignificantLocationChanges ? It worked for me.
