Linking Error after migrating IOS Project to Xcode 7.3.1 (Simulator and IPad)

• I have an IOS-App SWIFT Project on XCode 7.2 on my older yosemite machine, which works and builds fine.
• I have a new MAC running "El Capitan" with XCode 7.3.1
• I have migrated my project to the new machine by just copying: the project folder, all external libraries and frameworks, imported provisioning profiles and keys
• My Project has no syntax errors anymore, after referencing all libraries to the new folder structure.

Now I build the project and I get the following error:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_SSZipArchive", referenced from:
      type metadata accessor for __ObjC.SSZipArchive in ViewController.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I don't know how to analyse this problem, thats why I am asking here. Any help ?

UPDATE

When trying to run on the IPAD I get the same error but referencing architectur arm64 :

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_SSZipArchive", referenced from:
      type metadata accessor for __ObjC.SSZipArchive in ViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
