The base SDK is set to iOS. But unlike before, I am unable to select iOS version instead it forces macOS on me. I think this is the reason I am unable to compile and get the following error: https://imgur.com/wJzCbKp
Attempted: Restart XCode. Switch to macOS and back to iOS.
EDIT: looks like all my other projects are set for macOS now. All of them have iOS as selected build settings and deployment target. Don't know why it is not syncing up.
Looks like it was an XCode update that prevents the APIs from linking up. I guess is Apple's way of blocking outdated xcode versions. I had to force quit xcode and all other projects running on Xcode. Then re-open xcode and the update for v.12.3 prompts and now everything is back to normal.
If you get the error, chances are your xCode is out of date because apple released a new version very recently. Try everything to find/ get it to update.

I have recently updated 14.0 version of Xcode and simulator. I am facing a strange issue that app is not removing from the simulator. Before this update it's working perfect but after updated its showing this behaviour. Have a look a below, I have tried with both Remove app and Edit Home screen option. Both of them did't work for me. I have also tried to delete app from App library it also did't work.
So, I just ran into this weird issue as well, but I found that it wasn't consistent. Sometimes I could actually delete the app and sometimes I couldn't.
I think I figured out how to delete it every time:
When the app is running, go into Xcode and press "Stop" (CMD + .)
Now delete the app from the simulator
It's a work-around, but it doesn't look like Apple wants to fix this issue or maybe it was never reported to them, I don't know, but this seems to be working for me at least.
I'm running macOS Ventura 13.1, Xcode 14.2 and an iPhone 14 (iOS 16.2) simulator, so basically the newest versions and it's still present.
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
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.
I have been having this Xcode problem for a couple of months where my iOS simulator stops working whenever i run any application on Xcode and says, "The simulated application quit." and "iOS Simulator could not find the SDK. The SDK may need to be reinstalled." I am running Xcode 4.3.3 and have iOS sdk 5.1 and everything updated but it happened on my previous version of Xcode also. I have tried reinstalling Xcode over 10 times now and have been posting this question for a while now. No one has been able to get a solution. I have even sent in a bug report to apple but i don't think they will respond. I have tried doing everything every other person that has this problem has been told to do in other threads. I'm honestly thinking about just buying a new mac and seeing if Xcode will work on that one or taking in my current one to get looked at by apple. So if anyone has any ideas please let me know.
Go to Xcode -> Preferences -> Downloads and make sure the "Target SDK" you have selected in your project is in fact installed under the Downloads windows. For me this magically was uninstalled. Once i installed the SDK that my app was using, all worked again
This worked for me: http://www.colinbowern.com/posts/the-simulated-application-quit
I just deleted the folder "6.1" under ~/Library/Application Support/iPhone Simulator
The I just launched again the app and the simulator recreated correctly the 6.1 folder.
Resetting the simulator settings (iOS Simulator > Reset Contents and Settings) resolved this issue for me.
I had the same issue. For me suddenly all the installed simulators (4.3 through to 6.0) stopped working. I then went to Xcode -> Preferences -> Downloads, and there I had the chance to update at least the 5.0 simulator. This is now working, yet I was not able to get the 4.3 or 5.1 or 6.0 to work.
I have personally experienced a weird thing with xcode regarding this issue. Sometimes the sdk is installed properly but it still gives this error. I have two classes, if I call first class from the app delegate then the ipad simulator works fine but when I call the second class then it gives the error that the sdk needs to be re-installed.
In my case when the error occured, I had two errors in the second class. When I corrected the errors after debugging, the ipad simulator started to work completely fine. This is quite weird but its not the problem with your sdk, the problem is somewhere in the code.
This just happened to me. I tried to launch with iPhone 5.1 Simulator, got the error "iOS Simulator could not find the SDK. The SDK may need to be reinstalled." I tried running iPad 5.1 Sim, which worked. I switched to non-retina iPad. Then I tried running iPhone 5.1 Simulator again, and it worked.
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.
