Approved pending correction of line 78 issue.

This syntax doesn't work. Isn't this a Python syntax? Shouldn't this instead be print("Job started with invocation ARN: \(invocation_arn)")?

If it works for you, I'd be interested to know how, since I get syntax errors on these lines:

 76 |         outputS3Uri: bucket
 77 |     )
 78 |     print(f"Job started with invocation ARN: {invocation_arn}")
    |            `- error: expected ',' separator
 79 |
 80 |     // Poll for job completion

/Users/ericsh/tmp/reel/Sources/main.swift:78:11: error: cannot find 'f' in scope

 76 |         outputS3Uri: bucket
 77 |     )
 78 |     print(f"Job started with invocation ARN: {invocation_arn}")
    |           `- error: cannot find 'f' in scope
 79 |
 80 |     // Poll for job completion

@monadierickx can you make this tiny update ? Thank you

[monadierickx]

Apologies for the delay, I fixed my mistake and the code should work correctly now.

[sebsto]

@shepazon code is fixed and branch is updated. Can you review again ? Thanks

One very small nitpick. The directory name for this example uses underscores while the previously existing example in the same directory uses hyphens for word separation. Ideally these would be the same. I won't insist on changing it but I'd be delighted if it were. :)

Other than that, LGTM.

I noticed the inconsistency too. I propose to fix this in a separate PR once the open PR's are merged. As that would allow me to make all bedrock runtime code examples consistent.

If that is the way you want to go, would you prefer all hyphens, underscores or CamelCasing? The convention within the code examples was not clear to me.
