A third part company has provide me a Framework. I would like to check the swift version embedded in the framework (2.2, 2.3 or 3.x) The framework directory include libswift dylib files.

How to check the swift version used in the framework ?

Thanks !

You can use otool to print all versions of included binaries in the framework:

otool -l /path/to/your/FrameworkName.framework/Versions/A/FrameworkName

How do I use an external framework in my project?, I haven't been able to use any third-party frameworks in an Xcode project. instance of the library is to be used with Release, Debug, Simulator, or Device builds) then you likely want to link them as *embedded frameworks. That means the guy using your closed-source framework has to be using the same version of Swift in their Xcode for their project as you did for compiling the library, even if he's not using Swift in his code because ultimately it's his version of Swift that gets bundled into the app and your SDK runs against.

You can use Oskars answer to get the swiftlang version (in your case: 703.0.18).

Now you just have to lookup for the Swift version in the following table:

Swiftlang version            Swift version
-                            -
swiftlang-602.0.49.3         1.2
swiftlang-602.0.49.6         1.2
swiftlang-602.0.53.1         1.2
swiftlang-700.0.59           2.0
swiftlang-700.1.101.6        2.1
swiftlang-700.1.101.15       2.1.1
swiftlang-703.0.18.1         2.2
swiftlang-703.0.18.8         2.2
swiftlang-800.0.46.2         3.0
swiftlang-800.0.58.6         3.0.1
swiftlang-800.0.63           3.0.2
swiftlang-802.0.48           3.1
swiftlang-802.0.51           3.1
swiftlang-802.0.53           3.1

So 703.0.18 means Swift version 2.2.

  • in my case the path to binary was slightly different: otool -l /path/to/your/FrameworkName.framework/FrameworkName
  • Note that otool -l did not work for me, as the framework did not have a Versions folder. I used otool -L on the binary within instead.
