dyld: Library not loaded: @rpath/libswiftCore.dylib

I am trying to run a Swift app on my iPhone 4s. It works fine on the simulator, and my friend can successfully run it on his iPhone 4s. I have iOS 8 and the official release of Xcode 6.

I have tried

• Restarting Xcode, iPhone, computer
• Cleaning & rebuilding
• Revoking and creating new certificate/provision profile
• Runpath Search Paths is $(inherited) @executable_path/Frameworks
• Embedded Content Contains Swift Code is 'Yes'
• Code Signing Identity is developer

Below is the error in entirety

dyld: Library not loaded: @rpath/libswiftCore.dylib
  Referenced from: /private/var/mobile/Containers/Bundle/Application/LONGSERIALNUMBER/AppName.app/AppName

/private/var/mobile/Containers/Bundle/Application/LONGSERIALNUMBER/APPLICATION_NAME/Frameworks/libswiftCore.dylib

For me none of the previous solutions worked. We discovered that there is an "Always Embed Swift Standard Libraries" flag in the Build Settings that needs to be set to YES. It was NO by default!

Build Settings > Always Embed Swift Standard Libraries

After setting this, clean the project before building again.

For keen readers some explanation The most important part is:

> set the Embedded Content Contains Swift Code (EMBEDDED_CONTENT_CONTAINS_SWIFT) build setting to YES in your app as shown in Figure 2. This build setting, which specifies whether a target's product has embedded content with Swift code, tells Xcode to embed Swift standard libraries in your app when set to YES.

The flag was formerly called Embedded Content Contains Swift Code

Surprisingly enough, all i did was "Clean" my project (shift+cmd+K) and it worked. Did seem to be related to the certificate though.

I started getting this error when I removed:

@executable_path/Frameworks

from Runpath Search Paths in my build settings. Replacing it fixed everything up again (thank goodness for source control!)

I don't know how it got there, but it appears to be needed for a binary to find its embedded Swift runtime.

For the device, you also need to add the dynamic framework to the Embedded binaries section in the General tab of the project.

In Xcode 8 the option for Embedded Content Contains Swift Code option is no longer available.

It has been renamed to "Always Embed Swift Standard Libraries = YES"

Xcode 13 here (13.1 with react-native).

Created a clean react-native project and saw /usr/lib/swift as an entry in Runpath Search Paths.

After adding that, my project finally ran without crashing!

Nothing helped from what was suggested before.

I think it's a bug when certificates are generated directly from Xcode. To resolve (at least in Xcode 6.1 / 6A1052d):

1. go to the Apple Developer website where certificates are managed: https://developer.apple.com/account/ios/certificate/certificateList.action
2. select your certificate(s) (which should show "Managed by Xcode" under "Status") and "Revoke" it
3. follow instructions here to manually generate a new certificate: https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppDistributionGuide/MaintainingCertificates/MaintainingCertificates.html#//apple_ref/doc/uid/TP40012582-CH31-SW32
4. go to Xcode > Preferences > Accounts > [your Apple ID] > double-click your team name > hit refresh button to update certificates and provisioning profiles

I was having this issue with running my Swift tests (but not my app). It turns out that the test needed to have more than @executable_path/Frameworks in it's Runpath Search Paths build setting for the test target. Setting the Runpath Search Paths to the following worked a charm for me:

$(inherited)
@executable_path/Frameworks
@loader_path/Frameworks

OK, sharing here another cause of this error. It took me a few hours to sort this out.

In my case the trust policy of my certificate in Keychain Access was Always Trust, changing it back to defaults solved the problem.

In order to open the certificate settings window double click the certificate in the Keychain Access list of certificates.

This issue occurs again in Xcode 10.2. You must download and install the following package from Apple. It provides Swift 5 Runtime Support for Command Line Tools.

https://support.apple.com/kb/DL1998?locale=en_US

You have to set the Runpath Search Paths to @executable_path/Frameworks as showed in the following screenshot of Build Settings:

If you have any embedded frameworks made in Swift, than you can set to YES the Build Options Embedded Content Contains Swift Code.

I think Apple has already summarized it under Swift app crashes when trying to reference Swift library libswiftCore.dylib

As the AirSign guys state the problem roots from the missing OU attribute in the subject field of the In-House certificate.

Subject: UID=269J2W3P2L, CN=iPhone Distribution: Company Name, OU=269J2W3P2L, O=Company Name, C=FR

I have an enterprise development certificate, creating a new one solved the issue.

Let's project P is importing custom library L, then you must add L into

P -> Build Phases -> Embed Frameworks -> +. That works for me.

The most easy and easy to ignored way : clean and rebuild.

This solved the issue after tried the answers above and did not worked.

I was having the same problem after moving to a new mac, and after hours, trying all the suggested answers in the questions, none of this worked for me.

The solution for me was installing this missing certificate. http://developer.apple.com/certificationauthority/AppleWWDRCA.cer

Found the answer here. https://stackoverflow.com/a/14495100/976628

This error message can also be caused when upgrading Xcode (and subsequently to a new version of Swift) and your project uses a framework built/compiled with an older/previous version of Swift.

In this case rebuilding the framework and re-adding it will fix the problem.

Change Copy Pods Resources for the target from:

"${SRCROOT}/Pods/Target Support Files/Pods-Wishlist/Pods-Wishlist-resources.sh"

to:

"${SRCROOT}/Pods/Target Support Files/Pods-Wishlist/Pods-Wishlist-frameworks.sh"

I solved by deleting the derived data and this time it worked correctly. Tried with Xcode 7.3.1GM

After having tried out everything, I finally found out, that the build seems not always include every detail again and again. Maybe for speeding up the process... In order to ensure WHOLE packaging before running on a device, make a Clean first: Shift-Cmd-K. Then build with: Cmd-B. After that run it on your device. Easy. Kind regards to all you nice guys in that place!

In my case, it was just the name of my target :

I renamed it like this : MyApp.something and the same issue appeared. But I saw in the build Settings window, my product module name has been changed like this MyApp-something. So, I removed the dot in my target name (MyAppSomething) and the issue was gone.

For me, having tried everything with no success, what worked was to remove @executable_path/Frameworks from the Packaging section (don't know how it came to be in there in the first place)

We had a unity project that creates an xcode project that includes libraries that use swift.

We tried each and every reasonable suggestion on this thread.

Nothing worked. Code runs fine on new devices, and crashes on iOS<=12

It seems that swift is so smart, that even if you set it to "ALWAYS_EMBED_SWIFT_LIBRAIES"="YES" it does not include the swift libraries.

What actually solved the problem for us is to include a dummy swift file in the project. The file must contain calls to dispatch, foundation libraries.

Apparently this hints mighty-xcode to force include the libraries, but this time for real.

Here is the dummy file we added that made it work:

import Dispatch
import Foundation


class ForceSwiftInclusion {

   init() {
    
    // Force dispatch library.
    DispatchQueue.main.async {
      print("something")
    }

    // Force foundation library.
    let uuid = UUID().uuidString
    print("\(uuid)")

   }
}

For unity, also add project.AddBuildProperty(target, "SWIFT_VERSION", "Swift 5"); to your post processing for creating the xcode project.

None of the solutions worked for me. Restarting the phone fixed it. Strange but it worked.

none of these solutions seemed to work but when I changed the permission of the world Wide Developer cert to Use System defaults then it worked. I have included the steps and screenshots in the link below

I would encourage you to log the ticket in apple bug report as mentioned here as Apple really should solve this massive error: https://stackoverflow.com/a/41401354/559760

What worked for me in Xcode 11 was going to General -> Frameworks, Libraries, and Embedded Content and changing the "Embed" option for the framework in question to "Embed & Sign"

Xcode 7.2, iOS 9.2 on one device, 9.0 on other. Both had the error. No idea what changed that caused it, but the solutions above for the WWDR were correct for me. Install that cert and problem solved.

There are lot's of answers there but might be my answer will help some one.

I am having same issue, My app works fine on Simulator but on Device got crashed as I Lunches app and gives error as above. I have tried all answers and solutions . In My Case , My Project I am having multiple targets .I have created duplicate target B from target A. Target B works fine while target A got crashed. I am using different Image assets for each target. After searching and doing google I have found something which might help to someone.

App stop crashing when I change name of Launch images assets for both apps . e.g Target A Launch Image asset name LaunchImage A . Target B Lunch Image asset name LaunchImage B and assigned properly in General Tab of each target . My Apps works fine.

For me building a MacOS command line Swift app that depended on 3rd party Swift libs (e.g. SQLite) none of the above solutions seemed to work. What did work was directly adding the following path to my Runpath Search Paths in the Build Settings:

/Applications/Xcode.app/Contents//Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/

Doing that did give a warning at runtime saying that Xcode had found 2 versions of libswiftCore - which makes sense. Except that not including that line resulted in Xcode not finding any versions of libswiftCore.

Anyway, that'll do for me even if it doesn't seem right - my app is just a utility that I'm not intending to distribute and at least it runs now!

I have multiple version of Xcode installed at the same time. The framework was built with a newer version of Xcode. The app that I tried to compile was with an older version of Xcode. When I cleaned and compiled both the framework and the app with the same version of Xcode then things worked.

I started getting this similar error for testing adding S3 file using AWS services. Below was the error. dyld: Library not loaded: @rpath/AWSAutoScaling.framework/AWSAutoScaling

I searched a lot and above solutions are also not helpful for me. Below link helped me to solve this issue.

Which says to fix this issue by re-downloading the WWDR (Apple Worldwide Developer Relations Certification Authority).

I am on Xcode 8.3.2. For me the issue was the AppleWWDRCA certificate was in both system and login keychain. Removed both and then added to just login keychain, now it runs fine again. 2 days lost 

I'm using Xcode 8.3.3 and Xcode 9.2. The solution for me was to switch my default Xcode from 8 to 9 using Xcode Select:

$ xcode-select --print-path

$ sudo xcode-select -switch /Applications/Xcode-9.2.app

Edit: Actually what seemed to help here was that Xcode 9.2 used the derived data from Xcode 8.3.3. Not a solution but at least it allows me to move forward with my work.

If you're getting an error like this:

> The bundle "YourFrameworkTests" couldn't be loaded because it is > damaged or missing necessary resources. Try reinstalling the bundle. > (dlopen_preflight(/some/path/.../YourFrameworkTests.xctest/YourFrameworkTests): > Library not loaded: @rpath/SomeOther.framework/SomeOther Referenced > from: /some/path/...)

and use CocoaPods in your framework, then try to edit the Podfile and remove inherit! :search_paths from the Test target, and run pod install again.

For more details, see https://github.com/CocoaPods/CocoaPods/issues/8868.

I ran into this issue while I was trying to run unit-tests on a private pod.

I did everything everyone suggested. Nothing worked.

All I had to do was to run my unit-tests on a different simulator.

_{I didn't try resetting the contents and settings of my simulator, maybe that would have worked as well ¯_(ツ)_/¯}

For me none of above solutions worked.

I managed to get rid of the issue by creating an empty swift file inside my project. After that do a clean build and everything just worked!

Hope this helps others.

Tested on iOS 15 & React Native 0.66

To add on to the Enterprise distribution cert solution: you can open Keychain and inspect the cert. If there is any red text saying the trust chain can't be verified or it being revoked, it WILL NOT WORK! On my computer, our distribution cert was showing as revoked even though the web portal showed it as still valid. We got a new distribution cert, which was green (valid) in Keychain, and this solved the issue.

The above solutions did not work for me. I fix the issue by the following steps:

1. I had to go to the phone (Settings > Profile) and delete the profiles that were in the phone(including all the apps associated with those profile/provisions).
2. After that, make sure that you download the apple provisions in xcode. Go to xcode settings > account and sign in into your apple developer account.

I'm using Xcode 7.2. If you tried all of above and the error still occurs, try deleting the old certificate from Keychain Access! It's such a pain to finally fix this.

In my case,

I have set @executable_path/Frameworks

But I have to also set "Framework search paths"

$(PROJECT_DIR)/Frameworks

change as recursive

Which works for me.

When Xcode asks you to reset certs, you reset it. And the app can be run on actual device without crash with that error messages. Once this problem is fixed in one swift project. Other swift projects with this problem are fixed also.

I have struggled for these about half a day and I found that reset certs again and again in provisioning portal doesn't help.

In my case, one of my testing targets was working but the other one was not. It was giving the above error with a missing library or whatever. I compared the settings for both of the testing targets and found that one was missing the configuration for "Test Host", so I copied that from the working test target and it fixed my broken test target!

From the post of https://github.com/CocoaPods/cocoapods-integration-specs/pull/24/files, that mean swift.dylib need sign but failed. I failed even create a new swift project with cocoapod support.

If your project has cocoapods and different schemes, try running pod update, that fixed it for me.

Shortly speaking, have you tried to check "Enable Bitcode=NO". It works for me.

In my case, my project was written in Object-C and includes one 3rd party framework written in swift. I can run my APP on both simulator and real device in developer mode. However, once I achieved the APP with Ad-hoc provision profile and installed this ipa OTA on real device, it crashed. Not even mention upload to store. Hope this information can help.

I have the same issue, and the issue is like this:

dyld: Library not loaded: @rpath/Result.framework/Result Referenced from: /private/var/mobile/Containers/Bundle/Application/74AD1FE2-7095-47D2-B059-520863050EE2/ReactiveCocoaTest.app/Frameworks/ReactiveCocoa.framework/ReactiveCocoa Reason: image not found

My solution is below:

In the TARGET -> Build Setting -> Other Linker Flag -> delete the ReactiveCocoa framework. If is xxx.framework, you know, you should delete the xxx.

delete the ReactiveCocoa

I tested all of the above solutions but nothing solved the problem. I was using Xcode 10.2 and macOS 10.14.3. first i installed swift 5 runtime support for command line tools but nothing changed second i updated OS to 10.14.4 and nothing changed third i updated Xcode to 11.2.1 and the problem solved (do not user Xcode 11.2. it has archiving issue and deprecated)

Got the same issues after two years. I think this post explains the reason I got (But may be not the reason in this question). Use subscribed developer account or static libraries could help. Like remove use_frameworks! in your Podfile .

In my case, This is a bug of the early version iOS13.

For Xcode 12.x, what worked for me is go to General > Frameworks, Libraries, and Embedded Content. Then, choose Embed & Sign all Agora frameworks. (it was defaulted to Do Not Embed.

Me also got the exact same error in Xcode 13, iOS 12 mobile.

Here my project deployment info is 12.0, but my framework deployment info in iOS 15.0.

I have changed my Framework deployment info into 12.0.

Conclusion:

Which means framework and project supported versions issue. We need to fix the framework minimum support version after creating the framework.

Nothing worked for me, then i did these steps below:

1. I removed the flipper usage from podfile. It looked like this for me:

   use_flipper!({ 'Flipper-Folly' => '2.5.3', 'Flipper' => '0.87.0', 'Flipper-RSocket' => '1.3.1' })

2. I added a swift file in my project to create a bridging header.

I tried to read through all the answers. (Maybe missed some) But here is my solution. Might be helpful to someone. I just created a swift file (void.swift) in my project. When I added this file, it asked me to create a bridge. I said yes. That's all! It started working. Background: My project is written in obj c. And I added FBSDK pods to my project. After that, I started getting this error.

Following these steps worked for me:

• Click on your project name (very top of the navigator)

• Click on your project name again, (not on target)

• Click the tab Build Settings

• Search for Runpath Search Paths

• Change its value to $(inherited) flag (remove @executable_path/Frameworks).

For me solution is here below Disable the "Embed Asset Packs in Product Bundle" and this issue will be gone
