Yesterday i was testing my app in the iOS simulator and everything was working fine. I then decided to run the app on my iPhone and i got the error unable to install application, Unknown error occurred this has happened before so I cleaned my build folder (as this has fixed this issue before) however, the same error occurred. I then ran the app in the iOS simulator again and now i get the error Unable to run app in Simulator, An error was encountered while running (Domain = LaunchServicesError, Code = 0). I find this very weird as i didn't change anything besides trying to run the app on my iPhone. I have tried every solution given on this post and still no luck.
I'm sorry if my question doesn't contain much detail but as I said I didn't change anything and it was building and running fine a minute before plugging in my iPhone and trying to run it on there.
Any help would be much appreciated.
edit
I tried running other projects (with and without extensions) and they are working on both simulator and iPhone, therefore the problem must be within my project. (my project does have a today extension)
In that kind of cases I usually :
Product > Clean
Close xCode
Delete the Derived Data (in ~/Library/Developer/Xcode/DerivedData subfolders)
Delete the app on the iPhone
Reboot the iPhone
Restart and rebuild
I had this problem. In my case, it was caused by the Build value being blank. After putting a value there, and resetting the simulator once more, the issue went away.
I had the same problem and checking the system log carefully helped me to identify a coliding library that was causing this error. You can also check this answer if you are using extensions.
Generally it means there is a problem with the build, it may be due to old cache (solved by a clean build) or a project definition error (missing library, bad definition in info.plist, etc).
In my case it happened only on iOS 8, turns out that my widget had the wrong bundle ID.

I've finished working on a Cocoa (not iOS) application with Swift 3. I've tested it on a desktop computer. It works fine. I've tested it on another desktop computer. It works fine. I have even managed to send it over to iTunes Connect. But I have not submitted it because the same application fails to run on a MacBook Pro (2013). Anyway, I've tested it on a MacBook Pro with a retina display. That's when the entire problem started happening. Actually, this desktop application ran on the same MacBook Pro a few days ago. I think it was not sandboxed yet. Now, every time I send a binary copy that runs on different iMac models to MacBook Pro through AirDrop and try to run the application, I get an error that says EXC_CRASH (Code Signature Invalid). So I've deleted some files inside Developer /Xcode / DerviedData. Now, I cannot even debug the application. When I debug it, it hangs up with a fatal error message, which I have never seen before.
Now, if I double-click on an application that Xcode has generated, I get a crash report that says Library not loaded: #rpath/libswiftAppKit.dylib. I thought that I might have deleted some system files by accident. But if I debug existing macOS and iOS apps, I have no problem running them. Fortunately, the entire problem occurs on this particular Xcode project.
One topic that I've found here suggest that we set the Always Embed Swift Standard Libraries option to Yes. I've done that with no vail. I have also read a suggestion that says something about setting the When using this certification option on a developer certificate to Use System Defaults, which doesn't help. Another suggestion that I've tried is clearning cache (Command + Shift + Option + K).
If you have any suggestions, please let me know. Thanks.
More information
I have also seen a bizarre alert message repeatedly on MacBook Pro that says "%#" cannot be found. This error message poped up when I double-clicked on the application icon. It may refer to
String(format: NSLocalizedString("whatever", comment: ""), variable name)
I have solved the problem! I had the same problem with you. But from the answer in https://www.reddit.com/r/swift/comments/4nac9s/using_swift_frameworks_with_command_line/, I have known that the key is the rpath.
So I try to add this path to the project in the following two settings:
${DT_TOOLCHAIN_DIR}/usr/lib/swift/macosx/
Runpath Search Paths
Library Search Paths
I don't know why need to add both the two settings, but it works!
Recently, after upgrading to Lion and Xcode 4.2.1 I am getting this error when trying to run my app on my iPhone 4S:
"The application bundle does not contain a valid identifier."
My identifier is indeed valid, and I have been able to run my app with this identifier earlier.
The problem might appear when I change computers.
I have two computers that I am using to code my app, and I am using Dropbox to keep track of my files.
Restarting XCode, my mac and my iPhone does not work.
Cleaning the target and rebuilding does not work.
The only thing I have been able to do to fix it is to create a completely new project and moving my files. This made things work until I swapped computer. Now I am in the same trouble again.
Any idea? Anyone?
Three suggestions:
Check that your developer key is in both computers
Did you try to update the project? There is a strangly-named key in the middle bottom under the project's properties. Try this.
I had similar issues. I found that some things weren't updated when I updated osx and xcode. To get out of the situation, I would suggest creating a new project and copy paste code, files and build settings. This might seem stupid, but you know apple is not good at creating IDE's. You might just get your self lost in the undocumented settings.
No matter what I try, I get an Argument is Invalid error in Xcode when I try to build to my iPhone. It works fine in the simulator. The problem is not specific to one project, it happens with any project, even when I create a new one. When I run the console it displays this
I tried deleting and re-adding the provisioning profiles, and I've gone through every setting to look for spaces because I heard these can cause this error. Can anyone help? I don't know what else to try.
If you have a symbolic link (ln -s) in your project directory, it will work on the simulator, but cause a “The argument is invalid” error if the target is a real iOS device. (Xcode 4.5.2)
You may check if you have a space somewhere in the settings, such as the product name or so. These cause these kind of errors in many cases....
Also sometimes a symlink in your bundle can be the reason - depending on how you set up your file structures in the app bundle...
Actually this looks like and xcode error because it cant find those .m files. So here is a post that responded to hopefully it helps. It looks like you are gonna have to do some installation and reinstallation. XCode Update - iOS Link Error
I am assuming you are working with Git. This often happens due to issues in your local build. Take the latest pull from the develop branch and check if this solves your issue. If this doesn't work, you might want to manually check the build settings for your app.
Today, after installing Xcode 4 with the 4.3 SDK, I attempted to launch my application. However, the application will build and the iOS Simulator will pop up, but I get a message in the window in Xcode that says "Attaching to YourApp" which stays there indefinitely. How can this problem be fixed?
I had the same problem, that is, when I launched my application in the simulator, Xcode was hung waiting for the simulator to start. The simulator showed a black screen - nothing at all.
Note this is a project that ran fine on Xcode 3 and is the exact set of files used to build the application that is currently for sale at the App Store.
Okay, so here's the underlying problem, and my solution:
My application name was "ultimateTimer.app", as seen in Xcode under the Products folder. However, this was NOT the name in the project file.
Here's how to found out:
Click on your project in Xcode (it's usually at the top, e.g. mine is called ultimateTimer.xcodeproj). Under "Build Settings" tab, look for the "Packaging" area and specifically for the "Product Name" variable. Under Product Name, I had three entries:
Debug
Distribution
Release
Under Debug, it had the value "TalkUltimateTimer" which was an old name of mine. When I changed this to "ultimateTimer" to match the "ultimateTimer.app" as above, I found the Xcode attached to the simulator correctly.
This happened for me for iPhone applications. I opened the simulator myself and switched the device to iPhone Retina Display and from then on it worked. I tried switching back, but it didn't work again, so I have had to keep it on the Retina Display simulator, and if I need to test non-Retina Display I'll use the iPad simulator.
I skimmed the post and these seem to be the two solutions thus far:
I think I figured out the problem:
I went to 'Edit Schemes', and for some reason, the scheme I was using was pointing at BumpDev.app as the executable instead of bumpdev.app. Changing this made things work. Perhaps there is an issue when converting from xc3 proj files?
Anyways, the app now boots in the simulator. Yay!
And the other solution in that post is:
Did your project by any chance have a folder reference with images in it?
For me the problem only happens when I have a folder reference in the project. When I remove the folder reference and instead add the folder as a group, clean the project, and hit launch things work fine. In the "Copy to Bundle" phase each image is then listed individually, whereas when I had a folder reference, the whole folder was listed.
This took me a really long time to figure out. It was quite frustrating, but I'm glad I have a workaround until the bug is fixed.
I had the same problem after swapping the mouse for a new one. restarting my iMac resolved the issue.
I just upgraded to Xcode 4.3.2 and had the same issue with new projects. After poking around and comparing projects, I found out that new projects were set to the LLDB dbugger and the projects that worked were using GDB.
After changing the debugger for the new project to GDB, it worked. I am yet to research what the differences are, but at least I can now run my new projects.
Ensure you are starting a proper scheme.
I. e. when using CocoaPods, running Pods scheme would not start emulator.
It's a known issue. Have a look at this thread in the official forum.
Hey, update Xcode to 4.0.2. Problem solved :)
I had the same problem, I tried every solution here, but no works. Finally, after I rebooted my computer, the problem was gone.
Restarting the simulator worked for me
HI there,
Some users of my application have reported me that my application is no longer working. It closes just after launching it.
I have been trying to identify the crash for days with no luck using builds debug and release and testing it in several devices. This morning I was surprised when I was able to reproduce the problem by generating a AdHoc version and installing it on my iPhone.
I have already tried to remove all the custom configurations and recreate them using a copy of the release version but it did not work.
I got this error below when I was running in the simulator and the crash reports also points to the same place...
Detected an attempt to call a symbol in system libraries that is not present on the iPhone:fwrite$UNIX2003 called from function -[My7zipExtract extract7zFile:]
So, my question is: What is the difference between build Debug/Release and Distribution (App Store/Ad Hoc). I have double checked everything and the only difference are the certificates.
Any help is appreciated.
Many thanks
I'm having precisely the same problem right now. I copied my Debug Xcode configuration to create the AdHoc one, adding entitlements and changing the certificate.
Doing good old printf-debugging ;) i found that the c++ constructors seem to be called differently / not called at all on the iPhone when using the AdHoc build.
