OS X Framework Library not loaded Image not found

Question

I am trying to create a basic OS X Framework  right now I just have a test framework created  TestMacFramework framework and I m trying to import it into a brand new OS X Application project   I have built the  framework file and imported it into the new project  The framework appears to link okay  and I can reference the public header file I added to the framework build phases section   However  when I try to run the container Application I get the following Error   dyld  Library not loaded   Library Frameworks TestMacFramework framework Versions A TestMacFramework   Referenced from   Users samharman Library Developer Xcode DerivedData TestMacContainer-dzabuelobzfknafuhmgooqhqrgzl Build Products Debug TestMacContainer app Contents MacOS TestMacContainer   Reason  image not found   After a bit of googling I realised I needed to add a Copy Files section to my container application build phases  so I have done this and set it up like so       However  I am still getting the runtime error  I m obviously doing something wrong here  but the Apple developer library resource for this references Xcode 2  so isn t very helpful   What have I missed   UPDATE   I can see in the build log that my TestMacFramework framework is being copied into the  app contents frameworks directory  but it isn t being installed to the Library Frameworks directory on the HD    UPDATE 2   The build links correctly if I manually copy the TestMacFramework framework into the Library Frameworks directory

So I managed to get it working  it s quite simple when you have the right instructions  What I was looking for was a  private  framework which lives in the App bundle rather than being written to the system library folder   Building The Framework   Add a target to create a Cocoa Framework Within that targets  Build Settings  configure the  Installation Directory  to   executable path    Frameworks  Build library  and access the  framework from the archive or products directory   Including The Framework   Drag the created  framework file into the Xcode Project  be sure to tick  Copy Files to Directory  In the containing applications target  add a new  Copy File Build Phase  Set the  Destination  to  Frameworks  Drag in the created  framework

What solved it for me was changing abstract target to target for the main target in my Podfile  I had previously set it to abstract target and this caused the described error  Now it works like a charm

When you drag a custom framework into a project under Xcode 10 1  it assumes that the framework is a system framework and puts the framework into  Link Binary With Libraries  section of  Build Phases  under your target     System frameworks are already on the device so it is not copied over to the device and thus cannot execute at runtime so KABOOM   crash in   abort with payload  and disinforming error   Reason  image not found    This is because the framework code is not copied to the device     In reality  to have Xcode both link the custom framework and ensure that it is copied along with your code to the iOS device  real or simulator  the custom framework needs to be moved to  Copy Bundle Resources   This ultimately packages the framework along with your code executable to be available on the device together   To add a custom framework to a project and avoid the Apple crash    Drag custom framework into your iOS project file list Click ProjectName in Navigator -  TargetName -   Build Phases  -  Link Binary With Libraries disclosure triangle Drag custom framework out and down to  Copy Bundle Resources  section below  Xcode now moves the framework reference  fixed in Xcode 10  Run in simulator or device   The custom framework thus gets copied along with your code to your target device and is available at runtime      editorial  you would think Xcode would be smart enough to figure out the difference between one of it s system frameworks which need not be copied to the device and a custom framework that is  oh I don t know  in the project root directory hierarchy

I ran into the same issue but the accepted solution did not work for me  Instead the solution was to modify the framework s install name   The error in the original post is   dyld  Library not loaded   Library Frameworks TestMacFramework framework Versions A TestMacFramework   Referenced from   Users samharman Library Developer Xcode DerivedData TestMacContainer-dzabuelobzfknafuhmgooqhqrgzl Build Products Debug TestMacContainer app Contents MacOS TestMacContainer   Reason  image not found   Note the first path after Library not loaded  The framework is being loaded from an absolute path  This path comes from the framework s install name  sometimes called rpath   which can be examined using   otool -D MyFramework framework MyFramework   When a framework is embedded into an app this path should be relative and of this form   rpath MyFramework framework MyFramework  If your framework s install name is an absolute path it may not be loaded at runtime and an error similar to the one above will be produced    The solution is to modify the install name   install name tool -id   rpath MyFramework framework MyFramework  MyFramework framework MyFramework    With this change I no longer get the error

I think there is no fixed way to solve this problem since it might be caused by different reason  I also had this problem last week  I don t know when and exactly what cause this problem  only when I run it on simulator with Xcode or try to install it onto the phone  then it reports such kind of error  But when I run it with react-native run-ios with terminal  there is no problem    I checked all the ways posted on the internet  like renew certificate  change settings in Xcode  all of ways mentions above   actually all of settings in Xcode were already set as it requested before  none of ways works for me  Until this morning when I delete the pods and reinstall  the error finally gonna after a week  If you are also using cocoapod and then error was just show up without any specific reason  maybe you can try my way    Check my cocoapods version  Update it if there is new version available  Go to your project folder  delete your Podfile lock   Pods file  project xcworkspace  Run pod install

I tried many fixes  but what worked for me was to delete a missing target listed in the build tab of the build scheme  You can get to it by opening the edit window of the current scheme   Edit  My UI testing target was not working as well  and the solution I found was to delete it and generate it again

None of these issues solved this for me   The problem in the end was pretty easy  It looks like its a pretty major Xcode bug which I have logged the problem and fix under Apple bug  29820370   If you are struggling  as it seems like there are several pages of problems similar to this   then it would be great if you can raise a bug on bug reporter  https   bugreport apple com  and reference the bug I raised to gain visibility   I want to make Xcode back into the pleasure that it was before - and this is something I am sure Xcode should have fixed itself    Here is the fix   1   Open Keychain - go to Apple Worldwide Developer Cert   2  Double Click on it 3  Change the permission level from  always trust  to use System Defaults 4  Save and close it 5  Restart Xcode  Clean and build your project and it should be gone    Screenshot below of the correct settings   Hope this helps

For me this was the solution  after many hours of searching    For some reason  well into the development of a Swift 2 3 custom Framework  Xcode 8 had removed the DYLIB INSTALL NAME BASE setting from the project pbxproj file  A little walk into the Build Settings   Dynamic Library Install Name Base setting back to  rpath fixed it    from https   forums developer apple com thread 4687

Xcode 11     in Xcode 11 add framework into General- gt Frameworks  Libraries And Embedded Content   after adding make sure you select Embed  amp  Sign option

User · Answer

I found that this issue was related only to the code signing and certificates not the code itself  To verify this  create the basic single view app and try to run it without any changes to your device  If you see the same error type this shows your code is fine  Like me you will find that your certificates are invalid  Download all again and fix any expired ones  Then when you get the basic app to not report the error try your app again after exiting Xcode and perhaps restarting your mac for good measure  That finally put this nightmare to an end  Most likely this has nothing to do with your code especially if you get Build Successful message when you try to run it  FYI
