Question 1

How do I install Build Time Analyzer for Xcode?

Accepted Answer

You need to download the source code from GitHub, open it in Xcode, archive the project, and export the build, as per the README. This requires Xcode and basic familiarity with building macOS apps, unlike a simple app store download.

Question 2

Build Time Analyzer vs Xcode's own build time reporting?

Accepted Answer

Build Time Analyzer offers a more detailed and visual breakdown of Swift compilation times per function, while Xcode provides basic build duration logs. It's better for deep optimization but requires separate installation and manual use.

Question 3

Can I use Build Time Analyzer with CocoaPods or Swift Package Manager?

Accepted Answer

Yes, it works with Xcode projects regardless of dependency managers like CocoaPods or SPM, as it analyzes build logs from Xcode. However, results may not clearly distinguish between project code and external dependencies.

Question 4

How to interpret the results from Build Time Analyzer?

Accepted Answer

The app displays build times in a graphical interface, highlighting slow files and functions. Focus on items with high compilation times and consider refactoring complex Swift code, using type inference optimizations, or reducing dependencies.

Question 5

What are alternatives to Build Time Analyzer for Swift?

Accepted Answer

Alternatives include Xcode's build logs, command-line tools like xcodebuild with profiling flags, or other third-party apps. Build Time Analyzer is favored for its GUI simplicity but lacks automation compared to script-based solutions.

Question 6

Does Build Time Analyzer work with incremental builds?

Accepted Answer

Yes, it analyzes build logs which include incremental compilation data, helping identify functions that cause frequent recompilation and slow down iterative development in Xcode.
