What is the main benefit of using 'package traits' introduced in Swift 6.1?
iOS interview question for Intermediate practice.
Answer
To define different APIs or include optional dependencies based on the usage environment (e.g., Embedded Swift)[cite: 55, 56].
Explanation
Package traits in Swift 6.1 allow package authors to define conditional configurations[cite: 55]. This enables them to offer different APIs, features, or optional dependencies tailored to specific environments like Embedded Swift or WebAssembly[cite: 56]. This makes packages more versatile and adaptable[cite: 58]. Options A, C, and D describe other aspects of package management or build processes not directly addressed by package traits.
