Build configuration issues cause SourceKit crashes

7/10 High

Accidental misconfigurations in build settings (e.g., duplicate HEADER_SEARCH_PATHS) don't prevent compilation but cause SourceKit to crash on every text edit. Debugging requires manual inspection of SOURCEKIT_LOGGING output.

Query: “What are the most common pain points with Swift for developers in 2025?”4/4/2026

Accidentally introduce a duplicate set of headers in HEADER_SEARCH_PATHS? Degraded performance, and at worse, the compiler crashes everytime you edit text and SourceKit invokes the compiler.
