Swift and terminal: Using Google Endpoints in an iOS Client - terminal

Question

I am following the tutorial at
https://cloud.google.com/appengine/docs/java/endpoints/calling-from-ios
and when I get to step 5 and Open a new Terminal window to invoke ServiceGenerator. I get the error message in my terminal saying..
Barrys-MacBook-Pro:~ barrymadej$ /Users/barrymadej/Library/Developer/Xcode/DerivedData/ServiceGenerator-avaeguyitgyhxpcnaejpgzvxezei/Build/Products/Debug/ServiceGenerator \
/Users/barrymadej/Documents/AndroidStudioProjects/StudentProgressTrackerDatabaseAndCloud/backend/build/discovery-docs/myApi-v2-rpc.discovery /
ERROR: An output directory is required.
Usage: ServiceGenerator [FLAGS] [ARGS]
Required Flags:
--outputDir PATH
The destination directory for writing the generated files.
Optional Flags:
--discoveryService URL
Instead of discovery's default URL, use the specified URL as the
location to send the JSON-RPC requests. This is useful for running
against a custom or prerelease server.
--gtlFrameworkName NAME
Will generate sources that include GTL's headers as if they are in a
framework with the given name. If you are using GTL via CocoaPods,
you'll likely want to pass "GoogleAPIClient" as the value for this.
--apiLogDir DIR
Write out a file into DIR for each JSON API description processed. These
can be useful for reporting bugs if generation fails with an error.
--httpLogDir PATH
Turn on the HTTP fetcher logging and set it to write to PATH. This can
be useful for diagnosing errors on discovery fetches.
--generatePreferred
Causes the list of services to be collected, and all preferred services
to be generated.
--httpHeader NAME:VALUE
Causes the given NAME/VALUE pair to be added as an HTTP header on *all*
HTTP requests made by the generator. Can be used repeatedly to provide
additional header pairs.
--formattedName SERVICE:VERSION=NAME
Causes the given SERVICE:VERSION pair to override its service name in
files, classes, etc. with NAME. If :VERSION is omitted the override is
for any version of the service. Can be used repeatedly to provide
several maps when generating a few things in a single run.
--addServiceNameDir yes|no Default: no
Causes the generator to add a directory with the service name in the
outputDir for the files. This is useful for generating multiple
services.
--generatedDir yes|no Default: no
Causes a directory in outputDir called "Generated" to be created and
used to contain the generated files.
--removeUnknownFiles yes|no Default: no
By default, the generator will report unknown files in the output
directory, as commonly happens when classes go away in a new API
version. This option causes the generator to also remove the unknown
files.
--rootURLOverrides yes|no Default: yes
Causes any API root URL for a Google sandbox server to be replaced with
the googleapis.com root instead.
--verbose
Generate more verbose output. Can be used more than once.
Arguments:
Multiple arguments can be given on the command line.
service:version
The description of the given [service]/[version] pair is fetched and the
files for it are generated. When using --generatePreferred version can
be '-' to skip generating the name service.
http[s]://url/to/rpc_description_json
A URL to download containing the description of a service to generate.
path/to/rpc_description.json
The path to a text file containing the description of a service to
generate.
ServiceGenerator path:

Answer 1

You should generate a REST discovery document and use the new Objective C client instead. The client library you're trying to use is deprecated anyway. It looks like it didn't work because you specified the flag without the rest of the command, though.
