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 lt  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

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

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

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

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  gt  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

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
