I have compile webrtc ios source code ,then I used the command:
gn gen out/ios --args='target_os="ios" target_cpu="arm64"' --ide=xcode
then I open the workspace with Xcode.
but when I compile the code, Xcode gives me this error below.
An empty identity is not valid when signing a binary for the product type 'Application'. (in target 'AppRTCMobile')
my Xcode version is 10.2, the latest version.
I really don't know how did this happen,can anyone can help me?
my code sign setting is:
everything looks ok.
I added CODE_SIGNING_ALLOWED=NO as an additional parameter and that fixed this issue for me.
I needed to to turn OFF Automatic manage signing and turn it ON afterwards. It seems like Xcode did fix some inconsistency by that action.
I saw this error in Xcode 12.2b when building to run on a device, but I had not set signing to Automatic, or selected profiles, etc.
Basically I was running and testing on the simulator, then plugged in a device for testing and forgot to change any signing settings.
Perhaps this error is new to Xcode 12.x for that scenario.
If you're using CocoaPods check your project.pbxproj for (null) references, there's an issue that make BuildFile references to become (null)
Even if you have the identity correctly defined it may be "empty" because of this issue
Try, as suggested:
pod deintegrate
pod install
This error can occur when an Xcode project is generated (rather than built from within xcode), and the generated output project is unexpectedly in release mode.
I was working on a Godot project and got the above error which led me to this post. The error is not WebRTC or Godot specific.
If you only want to debug the project for now on a device, and don't need release builds yet, switch to a debug scheme using the scheme switcher (1)
If the generator didn't create a debug scheme, (which is the case for me for my issue) you can add one via New Scheme (2)
At first I could not work out why it was complaining about "empty identity" (this refers to the Team drop down) when as per the screen shot I had this value set. I had the project view filter settings on Debug (as per the screenshot (3) so the Release settings (where Team was set to "None") were not showing up. Change this to All to see if that is where the None in the error is coming from for you.
Debug builds only require a basic signing setup. If you still have issues with Release builds when it comes time for that, you may need to clear out certificates & provisioning profiles from your Derived Data, Apple Developer portal and Keychain.
Release build certificates are hard to manage & replace so be careful with randomly generating & deleting them.
The problem has been fixed, it's my mistake.
Select the target, then choose info.plist and select the one for your project.
Xcode 9.1
Simulator 10.0
OSX 10.12.6
I would like to upload a new build of my sticker pack to iTunes Connect. But Product > Archive is grayed out. So I ran the Simulator and got ""Failed to set plugin placeholders for (name)."
Only one answer anywhere in the whole world -- delete Derived Data Folder. I did and got same error message.
BTW Under General in Xcode the Version is 1. The build is 1.4. Does the build number have to be changed somewhere else as well?
What worked for me, Go to your target Build Phases and on "Embedded App Extensions" check the "Copy only when installing" checkbox.
I had the same problem today. In my situation I had a different identifier in my original app than in the extension identifier "base". The extension has to have the same identifier as the original app plus something else.
E.g:
Dummy App: com.company.dummy-app
Dummy App Extension: com.company.dummy-app.extensionName
After Xcode told me that, I changed my wrong names to look like above and then the problem occurred:
The problem was, that I had "automatic manage signing" turned on but Xcode didn't recognize that I changed the identifier.
Solution:
Just change the identifier again and check if "automatic manage signing" has created a new provisioning profile.
Deleting derived data may also helps.
It took me a while to find the fix for this. First go to build phases click the X beside the embedded and delete it. This should fix the problem it is what worked for me.
You must have different bundleIds for your project and extension.
Example:
App bundleId: com.companyName.appName
Extension bundleId:
com.companyName.appName.extensionName
I got this error when I set one configuration file for my project and notification service.
I changed the notification service configuration file to the correct one and this fixed my problem.
This is the solution:
app bundle identifier: com.SohaibSiddique.ShopApp
extension bundle identifier: com.SohaibSiddique.ShopApp.Notification
It may work for you.
Click details button in Error prompt and check the error log. In mycase it was "bundleVersion must be set in placeholder attributes for a plugin placeholder", Build version was empty in one of my target led me into this error.
A clean and rebuild will often fix this issue. If that doesn't work, try removing appex files which often cache items which xcode should have rebuilt:
find ~/Library/Developer/Xcode/DerivedData -name "*.appex" -exec rm -fr {} \;
Product->Clean Build Folder
Solved it for me.
It may also happen if the bundle identifier of the extension doesn't have the app identifier as a prefix.
E.g. this would raise the OP issue:
com.example.App
com.example.AppExtension
Instead:
com.example.App
com.example.App.Extension
will work as expected.
In my case, even though I was respecting the your.bundle.identifiex.<+extensionSuffixHere> format, I had both the Widget and AppExtension with the same bundle Id.
Apparently, even though on build time it doesn't create any problem, on runtime it gave me this error. So remember to set differently in case you're in the same situation!
First make sure your Bundle ID
com.apple.product
com.apple.product.topshelf
Then create a certificates from developer site and install
Now Clean Build folder and Run
It works now...!
Widgets Extensions
This can happen with embedded widgets when the NSExtension property is not set correctly in the Info.plist for the widget.
For me, one of my build targets had the wrong bundle identifier set (it was set to the bundle identifier of another target), hence the conflict / duplicate. I changed it to reflect its own Display Name and then the build worked again.
My Problem was that i malformed the info.plist from ShareExtension. Go line by line through your .plist script and check for wrong syntax or similar.
Upon updating to Xcode 9 and in the "launching" phase of compilation on the simulator I get the error:
Failed to create IXPlaceholder for app bundle ID
Emphasis placed on this issue only occurs trying to launch the simulator, as working with my actual iPhone 6s launches without any issues .
Attempts:
Ensured info.plist "Bundle Identifier" is correct. it is "$(PRODUCT_BUNDLE_IDENTIFIER)"
Checked to see if typing the bundle identifier manually would work, but it did not.
Project Cleaned
Deleted Derived Data
Xcode relaunched
Computer Restarted
Xcode betas uninstalled
Xcode Uninstalled and Reinstalled
Provisioning Profile Expires in 11 months
Automatically Manage Signing is unchecked then checked again
Paid Developer for 2 years now and have never had this issue before. Searched online for a solution with no luck and notice only a couple others have had this issue with no clear resolution.
What direction should I take to get this issue resolved. I don't see anything wrong with the provisioning files / certificates, but I could be wrong if someone could guide me in the right direction.
Thank you
I had same problem, this solve it
In you Info.plist:
Bundle_display_name : Dictionary
set to String value not dictionary
Bundle_display_name : String
i hope this help you
These steps helped me to fix this problem. I found this solution in this article
The only solution I have come across to continue being able to test your application on the simulator is to download the Xcode 10.3.1 simulators and select those to test your app on.
Best of luck to those who come across this bug!
I think i found solution for this. It works for my case. I did two things:
First(i think this is what really helps) :
in targets -> general-> Display name i set proper "App name" (i got i grayed before like seted placeholder)
I tried to set ${PRODUCT_NAME} but i got issues with that (but i think you should try this too)
General Display Name
the in proper info.plist. In bundle name set the same proper "App name".
Same here.I tried to set ${PRODUCT_NAME} but i got issues with that (but i think you should try this too)
Info.plist Bundle Name
Second(but i'm pretty sure that was a coincidence) :
I have other project that doesn't have this issue and works fine on all ios versions and simulators.
In this project(that one which works fine) i set Bundle Identifier from project that doesn't works, but like i said im pretty sure that was only a coincidence
Setting Display Name should fix this. Also making sure your identifier doesn't have funny characters (e.g. -)
Targets > General > Display Name
in my case, after upgraded system, it is fixed automatically
Reinstall Xcode.
Copy Xcode.xip from download Directory into Application Directory.
Install it.
Open your project and run.
This question already has answers here:
Unable to run app in Simulator : An error was encountered while running (Domain = LaunchServicesError, Code = 0)
(19 answers)
Closed 5 years ago.
I received an error (Domain = LaunchServicesError, Code = 0) when trying to launch my app in the iOS Simulator with Xcode 6. I looked for solution in google, but I didn't find anything practical.
What does this error mean?
This error indicates that there was a problem with installation. Unfortunately, Xcode does not actually print the contents of the error message that would give you more insight, but you can look at ~/Library/Logs/CoreSimulator/CoreSimulator.log to see the rest of the error details. There will also be more information about the problem in the simulated device's system log (~/Library/Logs/CoreSimulator/[Device UDID]/system.log); look for messages from installd around the time of the error).
Common causes for this include bundles missing an Info.plist, missing keys within your bundle's Info.plist, or values for some keys in the Info.plist not being allowed.
If your app's Info.plist does not contain a valid CFBundleVersion key/value pair, it is possible that your app may install correctly the first time but fail to update. Many users seem to work around this by doing a "Reset Contents & Settings" after each install, but it would be better to fix the root cause by setting an appropriate CFBundleVersion in the Info.plist. I believe iOS 8.2 now correctly returns an error on the first install in this case rather than just on updates, so hopefully this problem will be more obvious now.
Users with home directories on file systems that do not support hard links (eg: network home directories via AFP, SMB, or some NFS servers) may also run into problems related to hard linking. If this is the case, I suggest you create a path on your local HFS+ filesystem for simulator development (eg: /var/simulator/[user]) and create a symlink to that path from ~/Library/Developer/CoreSimulator. This particular issue was fixed in one of the iOS 8.2 betas.
In another case, the Build&Run would always succeed on the first try, but subsequent attempts would sometimes fail due to a changed Info.plist (eg: because someone's build system settings result in CFBundleVersion being different on each iteration). You can usually recover by either deleting the installed app (using a long-press from the home screen or xcrun simctl uninstall [Device UDID] [app identifier]) or erasing the device back to a default state. To erase the device, execute xcrun simctl erase [Device UDID] from terminal or choose Erase Contents & Settings from the iOS Simulator menu. This particular issue was fixed in one of the iOS 8.2 betas.
A newer instance of this issue is occurring for Xcode 6.2 users. If you have a WatchKit App Extension bundled in your app, it will fail to install to versions of the iOS Simulator runtime older than iOS 8.2. As a workaround, you will need to manually disable the app extension from installing when you want to test with iOS 8.1 and earlier runtimes.
If you need more specific help, please provide the entirety of the error message from CoreSimulator.log and any messages from installd and CoreSimulatorBridge that appear around the same time in ~/Library/Logs/CoreSimulator/[Device UDID]/system.log as that will reveal the underlying problem.
Does your project include a widget or extension? If so, the problem could be the bundle identifier of your widget/extension. It should be the same as the main target, appended with a period and an extra string. So for example:
Main target: com.mycompany.myapp
Widget should be: com.mycompany.myapp.widget
I fixed it by resetting the simulator:
iOS Simulator > Reset Contents and Settings...
Since everyone writes what they went through and how they fixed their exact problem, that might be unhelpful.
The problem is that there are different causes for the same error message and the right way of solving it is to open up ~/Library/Logs/CoreSimulator/CoreSimulator.log and look in there for the last message. This message gives you a good clue and sets you on the right path of solving your problem (sometimes it's bundle IDs, sometimes it's a missing or an extra attribute in the Info.plist, but you always get a good, descriptive clue).
This is how you narrow down the problem and eventually get to fix it.
Good luck and tough nerves with Xcode .)
Z.
For me I just cleaned the project and it worked -> Product -> Clean
TLDR: Clear your Project Build Folder - and you will be free of this pain.
( plus I logged this as a bug with Apple as they need to find a way to fix this in Xcode )
None of these solutions worked for me - I banged my head against several walls.
I looked at the CoreSimulator log and I realised that it was trying to build a library that I had deleted.
I couldn't find references to it anywhere.
Then I saw via another SO Question which unfortunately I can't find to reference, if you:
Hold down your option key then Product-> Clean option becomes Clean
Build Folder
Press that and enjoy having your error vanish
"Reset Content and Settings" from iOS Simutalor menu options and launching simulator after Quitting solved my issue.
In XCode 6
An error was encountered while running (Domain = LaunchServicesError,
Code = 0)
I had this error after making some major code changes to accommodate the iPhone 6 Screens. in Xcode 6 (iOS8)
I followed the options above and found that the only way to really get this fixed was by doing the following:
Deleted the derived data [go to Window >> Organizer >> (Find your App) Click on Delete next to the Derived Data]
Product >> Clean
Reset Contents and Settings in Simulator
Changed the Bundle Version to 1.4.1 from 1.4 in pList
Thank you for all the previous answers that got me to this stage. It worked a charm!
In my case, the error was caused because i didn't set the build id.
Setting this, launches the emulator without problem.
One other thing to try, that worked for me, after resetting the simulator and doing a clean build did not help, is clearing out the derived data. To do this: go to Organizer click on project click on delete derived data button. I had this happen after working on an extension for a while and went back to the regular branch. Hope this helps.
This is what caused the problem for me: the build number for the main app and the extension were different (I had incremented the main app build number to 1.0.1.03, but left the extension at 1.0.1.02).
Making them match fixed the problem for me.
Open the Console app and look there. In my case it told me exactly what to do. I saw:
ErrorDescription=WatchKit 2 app extension's NSExtension.NSExtensionAttributes.WKAppBundleIdentifier value does not match WatchKit app's bundle ID (found "com.myCompany.MyApp.MyApp.watchkitapp"; expected "com.myCompany.MyApp.watchkitapp").
So, I went to each plist and checked any items that related to a BundleID. Then Clean, relaunch, etc.
My case was about framework compilation. I have enabled the 'copy only when installing' option from Target- Build Phases- Embedded Frameworks-
I have an app that is set up to use different bundle IDs based on the build configuration. When creating my Apple Watch extension, Xcode generated everything using my Release ID, so I had to go through and change it all manually for debugging. Here's all the places I had to change it:
WatchKit Extension's Build Settings -> Packaging -> Product Bundle Identifier
WatchKit Extension's Info.plist -> NSExtension -> NSExtensionAttributes -> WKAppBundleIdentifier (this needs to use the same prefix as your companion app)
WatchKit App's Info.plist -> WKCompanionAppBundleIdentifier
The last one took me a while since the WatchKit App's Info doesn't show up as a tab when viewing the target settings, I had to go direct to the Info.plist file itself.
Try putting some number into [TARGETS]-[General]-[Identity]-[Version(or Build)], if they are empty.
It worked for me.
I hope it will help you.
I also have this error. In my case the log ~/Library/Logs/CoreSimulator/CoreSimulator.log was something like that :
Could not hardlink copy /Users/myUser/Library/Developer/CoreSimulator/Devices/60E569E7-6750-428A-A401-841BB081xxxx/data/Containers/Bundle/Application/70F24DDC-7954-46BF-B799-F807FD98yyyy/myApp.app to /Users/myUser/Library/Developer/CoreSimulator/Devices/60E569E7-6750-428A-A401-841BB081xxxx/data/Library/Caches/com.apple.mobile.installd.staging/temp.kOrJ9G/extracted/Payload/myApp.app with manifest /Users/myUser/Library/Developer/CoreSimulator/Devices/60E569E7-6750-428A-A401-841BB081xxxx/data/Library/Caches/com.apple.mobile.installd.staging/temp.kOrJ9G/extracted/com.apple.deltainstallcommands.com.mycompagny.myapp
thanks to this answer In look at my app info.plist. the key CFBundleVersion was missing so I add it and now everything is working !
None of the above worked for me, but this did:
I simply deleted IceCream.xcworkspace/xcuserdata/xcuserdatad and then reset the simulator and ran the app again. (Reseting the simulator alone, did not work for me.)
"Reset Content and Settings" from iOS Simutalor menu options and launching simulator after Quitting solved my issue.
The great explanation by Jeremy at least set me in the right direction, but despite having all the bundle identifiers and versions set correctly, the error still persisted. I then checked the Apple documentation which shows that the WatchKit extension (in its Copy Bundle Resources phase) copies the WatchKit app. This WatchKit app was named exactly the same as my iOS app, causing Xcode to confuse the two and read out the wrong plist, thinking the bundle identifier was incorrect. Renaming the Product of the WatchKit app to something distinct finally solved it for me.
If you've changed your bundle ID, make sure you do a clean build before trying to build it again! See how here: How to Empty Caches and Clean All Targets Xcode 4
So it's definitelly .plist problem. In my case it was empty NSExtensionMainStoryboard, removing this property fixed the problem
I had this error whilst trying to build Apple's Lister Xcode Project and run it on the simulator.
The essentials which fixed it for me were:
1) BundleID for the iOS App and the iOS Extension had to be different
2) I provide iCloud and App Groups for both targets
3) I used Xcode's "Fix Issue" to fix the issues
After that I could build and run the app without warnings or errors.
The clue from the log file was "... LegacyErrorString=DuplicateIdentifier, FunctionName=-[MIInstallableBundle performPreflightWithError:], SourceFileLine=450, NSLocalizedDescription=The parent bundle has the same identifier (com.ACMECompany.Lister) as sub-bundle at /Users/stephen/Library/Developer/CoreSimulator/Devices/5329928B-946B-40A4-B666-EFD11B96D11F/data/Library/Caches/com.apple.mobile.installd.staging/temp.HQ5d9X/extracted/Lister.app/PlugIns/Lister.appex"
Had a wrong app version set in InfoPlist.strings localization file. Urgh!
An hour gone!
Delete your simulator and regenerate one.
It works for me.
I removed the key in watch app's .plist file that shouldn't have been there. And the problem disappeared.
This worked for me:
In project settings -> General tab -> Identity section I changed the Version number from something like 2.0.2 (three digits) to 2.0 (two digits) then I deleted the app in the simulator and run the project again. No more error after that.
One other possible solution to add to all of the others that will no doubt stay above mine ;)
I deleted & later reinstated a Today Extension target retaining the source files, but after trying every solution under the sun, I realised it didn't have any sources or resources in its target! You might encounter this as well if your detailed launch services error can't find your compiled app extension file.
So, long story short, make sure your target has something included to compile or bundle in there. You can check your target memberships by selecting the relevant file(s) on your project navigator (on the left) and setting your checkmark(s) as appropriate in the file inspector (that's the first tab on the right).
I had the following in my log...
<Error>: Error Domain=LaunchServicesError Code=0 "(null)" UserInfo={Error=ExecutableTwiddleFailed...
This was due to there being no source files added in the extension project.
This error was showing up on my system when there was no hard disk space available. I freed up some space on my system for it to work.
My Problem was that the wrapper extension for the target project was unset.
To fix I had to go to target project -> build settings -> Packaging -> Wrapper Extension.
Set this to "app" (No quotes)
This fixed the problem for me

LegacyErrorString=DuplicateIdentifier, FunctionName=-[MIInstallableBundle performPreflightWithError:], SourceFileLine=450, NSLocalizedDescription=The parent bundle has the same identifier (com.ACMECompany.Lister) as sub-bundle at /Users/stephen/Library/Developer/CoreSimulator/Devices/5329928B-946B-40A4-B666-EFD11B96D11F/data/Library/Caches/com.apple.mobile.installd.staging/temp.HQ5d9X/extracted/Lister.app/PlugIns/Lister.appex"
Had a wrong app version set in InfoPlist.strings localization file. Urgh!
An hour gone!
Delete your simulator and regenerate one.
It works for me.
I removed the key in watch app's .plist file that shouldn't have been there. And the problem disappeared.
This worked for me:
In project settings -> General tab -> Identity section I changed the Version number from something like 2.0.2 (three digits) to 2.0 (two digits) then I deleted the app in the simulator and run the project again. No more error after that.
One other possible solution to add to all of the others that will no doubt stay above mine ;)
I deleted & later reinstated a Today Extension target retaining the source files, but after trying every solution under the sun, I realised it didn't have any sources or resources in its target! You might encounter this as well if your detailed launch services error can't find your compiled app extension file.
So, long story short, make sure your target has something included to compile or bundle in there. You can check your target memberships by selecting the relevant file(s) on your project navigator (on the left) and setting your checkmark(s) as appropriate in the file inspector (that's the first tab on the right).
I had the following in my log...
<Error>: Error Domain=LaunchServicesError Code=0 "(null)" UserInfo={Error=ExecutableTwiddleFailed...
This was due to there being no source files added in the extension project.
This error was showing up on my system when there was no hard disk space available. I freed up some space on my system for it to work.
My Problem was that the wrapper extension for the target project was unset.
To fix I had to go to target project -> build settings -> Packaging -> Wrapper Extension.
Set this to "app" (No quotes)
This fixed the problem for me
