Swift Package Manager binary targets vs manual XCFramework integration

Integrating Pre-compiled Binaries

Xcode allows the inclusion of proprietary libraries through two primary methods: integrating binary targets via the Swift Package Manager (SPM) or manually embedding XCFrameworks into the project structure.

While SPM binary targets simplify dependency resolution and versioning through the Package.swift manifest, the underlying linking behavior differs from manual drag-and-drop integration. Specifically, there is uncertainty regarding how Xcode handles search paths and framework bundling when a project transitions from manual XCFramework management to an SPM-based binary target approach.

When migrating to SPM binary targets, the project must maintain compatibility with existing build phases and target memberships without introducing duplicate symbol errors or missing library warnings during the archive process.

• How does the build system differ in handling the Framework Search Paths when a binary target is resolved via SPM compared to a manual XCFramework?
• What is the expected behavior for target membership and embedding when using binary targets in a multi-platform Xcode project?
