Hello, make sure that your command is right In origin:
export PATH=/Library/Developer/Toolchains/swift-latest/usr/bin:"${PATH}"
1) check is /Library/Developer/Toolchains/swift-latest symlink available, and you add ${PATH} at the end.
2) Also, could you please open Terminal and show result of commands:
env
ls -l /Library/Developer/Toolchains/
3) It will be easier to investigate if you create macOS command line project and put your code in it.
4) Do you have any other version of Xcode (any preview version?)
5) Restart you Xcode after applying changes.

REPL works well.

Finally I reproduced.
You created iOS or tvOS Playground project.
You should create macOS playground version.

I Solved mine by closing the simulator

As you can see, currently swift for TensorFlow built only for x86 platform.

lipo  -info /Library/Developer/Toolchains/swift-latest/usr/lib/swift/macosx/libswiftCore.dylib
Architectures in the fat file: /Library/Developer/Toolchains/swift-latest/usr/lib/swift/macosx/libswiftCore.dylib are: x86_64

Closed.
Currently, Swift for TensorFlow only supports macOS playgrounds. Make sure to select "macOS" when creating a playground!
