I think the way you linked static libraries is wrong. You need to define static libraries (.a) in dependencies of App target

dependencies:
      - framework: MyProject/iOSMagick-6.8.8-9-libs/file1.a
      - framework: MyProject/iOSMagick-6.8.8-9-libs/file2.a
      - framework: MyProject/iOSMagick-6.8.8-9-libs/file3.a
      - framework: MyProject/iOSMagick-6.8.8-9-libs/file4.a
      - framework: MyProject/iOSMagick-6.8.8-9-libs/file5.a

and don't forget to define LIBRARY_SEARCH_PATHS in settings of target:

settings:
      base:
        LIBRARY_SEARCH_PATHS: "$(inherited) $(PROJECT_DIR)/MyProject/iOSMagick-6.8.8-9-libs"
