Greptile Summary

This PR bumps the Apple SDK to version 17.1.1, removing the admin-only Advisor service and its five associated model files, and adding a sizeActual field to the File model.

• Advisor removal: Advisor.swift, Insight, InsightCTA, InsightList, Report, and ReportList are all deleted; the CHANGELOG now correctly lists all five removed models and the four matching example docs are gone.
• File model update: sizeActual: Int is added as a required (non-optional) field, decoded with a hard container.decode and force-cast as! Int in from(map:). Clients on SDK 17.1.1 pointing at a server version that does not yet include this field will receive a DecodingError.keyNotFound or a fatal crash on every file-related response (noted in a prior review comment that remains unaddressed).
• Version bump: x-sdk-version header and the README SPM snippet updated to 17.1.1.

Confidence Score: 4/5

The Advisor removal is clean, but sizeActual is decoded as a hard-required field with a force-cast, meaning any client targeting a server that omits this field will crash or throw on every file API call.

The Advisor deletions are straightforward and correctly reflected in the changelog. The only meaningful risk is in File.swift: sizeActual is decoded with container.decode (not decodeIfPresent) and accessed via as! Int in from(map:), with no server-version gating (x-appwrite-response-format is still 1.9.5). A client on this SDK version communicating with an older Appwrite server will hit a DecodingError.keyNotFound or a runtime crash on every storage endpoint. This issue was raised in a previous review round and has not yet been addressed.
