In @Cherrish-iOS/Cherrish-iOS.xcodeproj/project.pbxproj:
- Around line 280-286: The project file now forces manual signing
(CODE_SIGN_STYLE = Manual) and sets specific signing keys
(CODE_SIGN_IDENTITY[sdk=iphoneos*], DEVELOPMENT_TEAM,
"DEVELOPMENT_TEAM[sdk=iphoneos*]") and development asset paths; revert to a
team-agnostic, CI-friendly setup by either restoring CODE_SIGN_STYLE = Automatic
and clearing DEVELOPMENT_TEAM/PROVISIONING entries or, if manual signing is
required, document and commit instructions to ensure every developer and CI has
the named provisioning profile (cherrish-development) and certificate installed;
update project.pbxproj to remove hardcoded team IDs and provisioning settings or
add commentary for maintainers and then verify by producing a short confirmation
that the change allows other devs and CI to build ([request_verification]).
- Around line 9-11: Remove the explicit OSLog.framework linking entries from the
Xcode project: delete the PBXBuildFile entry with id 5126F89F2F0E9AF000E67E33
(the "OSLog.framework in Frameworks" build file), remove the corresponding
PBXFileReference with id 5126F89E2F0E9AF000E67E33 (the OSLog.framework file
reference) and any references to that fileRef inside PBXFrameworksBuildPhase or
other sections (the other occurrences noted in the comment). OSLog is provided
by the SDK and only requires import OSLog in source; after removing those
entries ensure there are no dangling references and run a clean build to verify
the project still compiles successfully.

In @Cherrish-iOS/Cherrish-iOS/Core/CherrishError.swift:
- Around line 39-40: The case .unknownError in CherrishError.errorDescription
currently returns nil; change it to return a sensible default string (e.g., "알 수
없는 오류" or "Unknown error") so errorDescription never yields nil for
unknownError; update the switch in the errorDescription computed property for
the CherrishError enum to return that default message for the .unknownError
case.
- Line 10: The enum CherrishError is implicitly internal but should be exported;
change its declaration from "enum CherrishError: Error, LocalizedError,
Equatable" to "public enum CherrishError: Error, LocalizedError, Equatable" so
the type (and any public cases or members) is usable outside the module, and
update any nested members or associated values to appropriate access levels if
needed.

In @Cherrish-iOS/Cherrish-iOS/Core/CherrishLogger.swift:
- Line 18: LogType and CherrishLogger are currently implicitly internal and need
to be usable across the module boundary; change their declarations to public by
adding the public access modifier to the enum LogType and the CherrishLogger
type (and any related declarations at the other occurrence referenced) so they
are exported from the module; ensure any methods, initializers, or nested types
that must be accessed externally are also marked public as needed.
- Line 108: The current code sets fileName using the compiler literal (#file)
which always yields "CherrishLogger.swift"; change it to use the incoming file
parameter so the caller's filename is logged by replacing let fileName = (#file
as NSString).lastPathComponent with code that derives fileName from the function
parameter (e.g., let fileName = (file as NSString).lastPathComponent), and
ensure the variable 'fileName' is used downstream in the log output.
- Line 11: The static property subsystem currently force-unwraps
Bundle.main.bundleIdentifier (static let subsystem =
Bundle.main.bundleIdentifier!), which can crash in tests or environments without
a bundle identifier; change subsystem to safely unwrap with a fallback (e.g.,
use optional coalescing or a computed property that returns
Bundle.main.bundleIdentifier ?? "com.cherrish.unknown" or similar) so it never
force-unwraps and always provides a safe default value.

In @Cherrish-iOS/Cherrish-iOS.xcodeproj/project.pbxproj:
- Line 10: The PBX file contains an explicit PBXFileReference for
OSLog.framework (the entry with name = OSLog.framework and path =
System/Library/Frameworks/OSLog.framework) and an associated Frameworks group
that are unnecessary; remove that PBXFileReference and any references to the
Frameworks group (the Frameworks group block that lists OSLog.framework and
related entries) from the project.pbxproj so OSLog is used via import OSLog only
and not explicitly linked in the project.

In @Cherrish-iOS/Cherrish-iOS/Core/CherrishError.swift:
- Around line 10-19: The enum CherrishError should be explicitly exported:
change the declaration of CherrishError to be public so it can be used across
the project (i.e., make the type public by updating the declaration for enum
CherrishError to include the public access modifier while keeping its existing
cases like DIFailedError, decodingError, URLError, networkRequestFailed,
networkConnect, networkError(code:message:), noData, unknownError, and
encodingError).

In @Cherrish-iOS/Cherrish-iOS/Core/CherrishLogger.swift:
- Line 11: The forced unwrap of Bundle.main.bundleIdentifier in the static let
subsystem constant is unsafe and can crash in tests or certain environments;
change the initializer for subsystem in CherrishLogger (static let subsystem) to
handle the optional safely — e.g., use nil-coalescing to a sensible default
identifier or fallback to another safe source
(Bundle.main.object(forInfoDictionaryKey: "CFBundleIdentifier") as? String ??
"com.cherrish.unknown"), or compute it lazily and guard-fail with a default, so
no forced unwrap remains.
- Around line 147-153: Change the static func error to accept an optional
message parameter (e.g., message: String = "") and pass that message into the
existing log call instead of the empty string; update the log handling for the
.error(error: Error) case inside log(...) to include and format both the
provided message and error.localizedDescription (so the log output shows the
custom context message plus the error details). Ensure you update the signature
of CherrishLogger.error and the .error case handling code paths that construct
the final log string.
