iOS app with framework crashed on device dyld Library not loaded Xcode 6 Beta

Question

This crash has been a blocking issue I used the following steps to reproduce the issue    Create a Cocoa Touch Framework project Add a swift file and a class Dog Build a framework for device Create a Single View application in Swift Import framework into app project Instantiate swift class from the framework in ViewController Build and run an app on the device   The app immediate crashed upon launching  here is console log   dyld  Library not loaded   rpath FrameworkTest03 framework FrameworkTest03   Referenced from   var mobile Applications FA6BAAC8-1AAD-49B4-8326-F30F66458CB6 FrameworkTest03App app FrameworkTest03App   Reason  image not found   I have tried to build on iOS 7 1 and 8 0 devices  they both have the same crash  However  I can build an app and run on the simulator fine  Also  I am aware that I can change the framework to form Required to Optional in Link Binary With Libraries  but it did not completely resolve the problem  the app crashed when I create an instance of Dog  The behavior is different on the device and simulator  I suspect that we can t distribute a framework for the device using a beta version of Xcode  Can anyone shed light on this

If have development pod Delete your app from simulator install from pod -  clean -    run again

For iOS greater than or equal to 8  Under the target s General tab  in the Embedded Binaries section add the framework  This will copy the framework into the compiled so that it can be linked to at runtime     Why is this happening    because the framework you are linking to is compiled as a dynamically linked framework and thus is linked to at runtime       Note    Embedding custom frameworks is only supported in iOS   8 and thus an alternative solution that works on older versions of iOS follows    For iOS less than 8  If you influence this framework  have access to the source code build process  you may change this framework to be statically linked rather than dynamically linked  This will cause the code to be included in your compiled app rather than linked to at runtime and thus the framework will not have to be embedded      How    Under the framework s Build Setting tab  in the Linking section  change the Mach-O Type to Static Library  You should now not need to include the framework under embedded binaries      Including Assets  To include things such as images  audio  or xib nib files I recommend creating a bundle  essentially a directory  more info here bit ly ios bundle  and then load the assets from the bundle using NSBundle

For any project or Framework project in Xcode that use pods  one easy way to avoid dynamic library  dylb  not to load is to set you pod file to ink in static mode  To do so  just make sure to don t write the following line in your pod file   use frameworks    Once the line deleted from your file which you saved  simply run form the console     pod update

The same thing was when I ve created a new Configuration and Build Scheme   So the solution for me was to run   pod install   for this newly created Configuration

Xcode 11   Navigate to settings of your target and select General  Look for  Frameworks  Libraries  and Embedded Content  Keep  Do Not Embed  and make sure that all your targets  if you have more than one  have only set it s own framework and not others targets

Surprisingly  not all of the necessary pieces are documented here  at least for Xcode 8   My case was a custom-built framework as part of the same workspace  It turns out it was being built incorrectly  Based on jeremyhu s last response to this thread   https   forums developer apple com thread 4687  I had to set Dynamic Library Install Name Base  DYLIB INSTALL NAME BASE  under Build Settings of the Framework Project and then rebuild it  It was incorrectly set to   LOCAL LIBRARY DIR  and I had to change it to  rpath   So in the link processing stage in the App Project  it was instructing the host App to dynamically load the framework at runtime from  Library Frameworks fw Framework fw  as in  the root of the runtime filesystem  rather than path-to-App Frameworks fw Framework fw  Regarding all the other settings  it does have to be in 3 places in Build Phases  but these are all set at once when you just add it to the Embedded Binaries setting of the General tab of the hosting App   I did not have to set up an extra Copy Files phase  which seems intuitively redundant with respect to the embedding stage anyway   By checking the tail end of the build transcript we can assure that that s not necessary   PBXCp  Users xyz Library Developer Xcode DerivedData MyApp-cbcnqafhywqkjufwsvbzckecmjjs Build Products Debug-iphoneos MyFramework framework    Many verbose lines removed  but it s clear from the simplified transcript in the Xcode UI    I still have no idea why Xcode set the DYLIB INSTALL NAME BASE value incorrectly on me

Try with changing flag ALWAYS EMBED SWIFT STANDARD LIBRARIES  in earlier xcode versions  Embedded Content Contains Swift Code  in the Build Settings from NO to YES

For SumUp Users  if you are loading the latest SumUpSDK xcFramework  then you need to make sure that it s set to  quot Embed  amp  Sign quot  from the application s General tab of the Target  i e  to reverse the above statement  making it easier to understand    Go to the  quot Project Navigator quot   i e  the first icon to show all project items etc   Select your project from the top of the tree   On the menu in the middle of the page  slightly to the right   select your application under  quot Targets quot   From the top-tab  select  quot General quot   Scroll down to  quot Frameworks  Libraries and Embedded Content quot   Select your Lib from the list  Select  quot Embed  amp  Sign quot  from the drop down list next to it   Clean  Re-Build and run    I hope this helps  H

You need to add the framework to a new Copy Files Build Phase to ensure that the framework is copied into the application bundle at runtime    See How to add a   39 Copy Files build phase  39  to my Target for more information   Official Apple Docs  https   developer apple com library mac recipes xcode help-project editor Articles CreatingaCopyFilesBuildPhase html

Just dragging the framework into your project isn t going to be good enough  That is like being in the same ballpark but not being able to find your kids  Follow these steps   1  Create your framework   Develop your framework  Once your development is complete  COMMAND B build your framework and ensure you receive  Build Succeeded       2  Access your framework   Once your framework project successfully builds it will then be ready for you to access in your Products folder in your project       Right click on your  framework and select  Show in Finder       3  Place framework in your project   Drag and drop the  framework from your Finder window to your app project s  Framework  folder      4  Configure app project for framework   Select the top level in your project      Choose your target      Go to  Build Phases   then  Link Binary with Libraries   and ensure that your framework is included with optional selected       Still in  Build Phases   go to the upper left and select the   button  In the drop down choose  New Copy Files Phase        Scroll down to the new  Copy Files  section and ensure that you set Destination to  Frameworks   Leave the subpath empty  Then click the   button at the bottom left        You will be presented with your project hierarchy  Scroll down to the  Frameworks  folder that you added the framework to in step 3  or search for it in the search bar at the top  Select your framework and click  Add        Ensure that your framework is included with  Code Sign On Copy  selected      5  Clean  then run your project   COMMAND SHIFT K COMMAND R
