I have multiple Xcode Apps installed in OS X 10.9.2 to check the compatibility. Now I am facing a problem when I run the app, this error occurs "iOS simulator failed to install the application". I want uninstall all Xcode completely to reinstall latest Xcode 5.1. How can I do that? Thanks.
Xcode Instances
/Applications/Xcode.app (Xcode v5.0.2)
~/Apps/Xcode.app (Xcode v4.6)
Use Appcleaner
or
Just drag and drop Xcode to trash from app folder
Looks like this is a known issue. From the -->>

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 have been building mac app on my mac mini and it always worked well but today i faced this error, searched a lot but no luck.
Message from debugger: unable to attach
What i tried:
Clear derived data
Quit Xcode
Restart machine
installation directory set to blank and also to /Applications
Tried Skip Install No / Yes
Using developer Signing certs
M using only Developer certificates and not provisioning profile to sign my cocoa app
Xcode 8.2
OSX 10.12.1
Please help :)
This is what fixed it for me, perhaps it will help others but I do realize the question was for 8.2. I had it set to Xcode 9 "New Build System" disabling this and switching to "Standard Build System" in the Project Settings under the File Menu. I had tried all the other things like killing DerivedData, clean build, restarting Xcode. I also verified that my dependent libraries were set correctly. The only thing that worked was disabling new "New Build System"
I just had this problem today. I have little demo code in a mac project(created with Xcode 9.4). This error just started to occur after I upgraded system to macOS Mojave 10.14. However, in Xcode 10 this project runs no problem(without changing anything). If you can use Xcode 10 it will probably be fixed.
Unfortunately, the above solutions didn't work for me (although I am sure they work for some people).
Here is what worked for me, in case this helps anyone else:
Close Xcode
Open Xcode and Create a new Xcode project
In the iOS template, select Single View App then click Next
yes, I know you are trying to get a macOS app attaching to the debugger :).
Give the iOS app any product name and organization identifier you would like and click Next
Create the new project anywhere you would like (I saved it to my desktop)
Build and run (cmd + r) the iOS app on a simulator like the iPhone 8 (starting a simulator and running the iOS app will take a little time, so have patients)
After the iOS app runs in the simulator, click to stop it from running (the stop button is next to the run button)
Open your macOS app that you are having trouble connecting a debugger to, and build and run it (cmd + r)
This, for some reason, allowed me to connect to the debugger with my macOS app...
Xcode version: 10.1, macOS Mojave version: 10.14.2
Can't see any iOS 9.0 simulators. In previous Xcode 7 beta 3 all was OK.
Can't install iOS 8.3 simulator.
Also I can't add any simulator from 'Organizer'. By pressing "Create" nothing happened.
Each time when I'm trying to download iOS simulator I see next thing:
One possible issue is that there may be old leftover simulators installed, which are not compatible with the new XCode, and their presence causes the whole Simulator to fail. To get rid of them, delete the simulators in /Library/Developer/CoreSimulator/Profiles/Runtimes (for me there was an iOS 7 simulator there which was the issue). Relaunch XCode after this.
Then try to run the simulator from XCode->Open Developer Tool->Simulator. Assuming this succeeds, verify that you have the simulators under the iOS Simulator menu Hardware->Device->Manage Devices… – if not, you should be able to click the + in the bottom bar to add yourself some iOS 9 simulators. Relaunch XCode again and they should show up in the menu.
In my case was with Xcode 8.2, what it worked to me was changing Deployment Version:
After setting another different than 10.0 then appeared back all simulators again.
Have you tried going to Xcode > preferences > downloads and trying to re-download the simulators you want?
For me it was only showing one simulator,
and when I go to Xcode > Preferences I can see the simulator is already downloaded but it is not showing up in the list,
if you're facing something similar. This is how you should add required simulator,
From the Xcode menu, open Windows > Devices, shown in the image below
you should see this screen,
notice there is only one simulator (ref: first image)
Now to add required simulator, you should click on the + (in the left corner)
You should see this,
You can choose the simulator from the list, In my case it is iPhone 6s Plus.
In Xcode you can see additional simulator iPhone 6s Plus,
I was also not able to see simulators.Reason is,I have not restarted system after upgrading Xcode.I restarted & simulator started displaying as routine.
There is a bug in the latest El Capitan beta which causes a process to crash when dlopen() fails to mmap() a dynamic library. Such mmap() failures can occur due to code signature verification failures.
These mmap() failures will occur if older iOS Simulator runtimes are present on disk (ie: installed from Xcode 6.x), and that is the reason why Xcode 7 beta release notes have indicated that earlier runtimes are not working in Xcode 7. The iOS 8.x Simulator runtimes were updated in newer downloads, but if the older versions are present on disk, they will cause the mmap() failure, which in the latest El Capitan beta, unfortunately results in the CoreSimulatorService repeatedly crashing which in turn results in no simulators being available.
If simulators are suddenly disappeared:
Just consider decreasing Deployment target to a minor version below current version in Project > Build Settings > Deployment Info > Deployment Target
P.S. Usually you see a place holder text showing the selected version (in gray) in the box denoted above. If for example the gray text says 9.3, then decrease it to 9.2.
Look at seancook's response in the middle of this page... it seems to have fixed this issue for several people.

Edit:
This can also be fixed by booting into recovery mode (CMD - R) and reinstalling El Capitan.
Go to Windows. Select Devices. Select '+' from left bottom and add all simulators one by one.
I had changed the name of my Project from Finder. I clicked on the old project name (between the Play Button and and the selector for the desired Simulator or Device), selected edit schemes, selected the Targets Tab, and realised that the old scheme was missing so I just added my new Project name by clicking on the plus button and the simulator list reappeared.
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:

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.
when i run the XCODE with ios 4.3 the default simulator is set to ipad ....I changed active executable setting to iphone simulator .. but stil its not working ..Whenever i open the XCODE again its restting back to ipad .. Is ther any other way to set this out ?
When building the app in the iPhone simulator, wait until the iPad finishes loading; if your app is displayed and working properly then (and only then) try switching to the iPhone simulator.
To keep the iPhone display as the default, try changing the program preferences from the simulator itself or from the Xcode project file in Xcode.
I installed iOS 4.2 on my 2nd-generation iPod Touch last week. I tried running my application on the device through Xcode, but it didn't work (because Xcode didn't yet support iOS 4). To solve that, I installed Xcode 3.2.5 and the iOS SDK 4.2. Now I can get the app to run in the iPhone/iPad Simulator just fine.
However, I can no longer select "Device" from the menu at the top of the screen. It's a choice, but when I try to click on it, it never actually gets a check mark.
Because of this, I can no longer run the app on my iPod. The other (related) problem is that I can't choose "Build and Archive" from the Build menu anymore because the target is not a device.
Why is this happening? Do I need to change some settings in my project, or something with my device itself?
EDIT: Upon closer investigation, it appears that I can't select anything but the iPhone Simulator 4.0. Maybe there's something wrong with the project file.
Check that the base SDK is set to Latest iOS (currently set to iOS 4.2) for your Xcode project and your target's product, then perform a rebuild and see if your iPod is recognized.
Also try visiting the Xcode Organizer and see if it's asking for anything from your iPod. Typically Xcode will want to collect some data from devices whose OS receive updates, so it can update itself and install your apps on the updated OS properly.
