Re: [swift-dev] Reporting/Debugging Slow Swift Compile Time

I've opened a few jira tickets: - https://bugs.swift.org/browse/SR-2901 for this bug (has some numbers on the impact in our project) - https://bugs.swift.org/browse/SR-2902 for adding the expression type checker timer, since it's looking like I won't have time to get to in the next 2 weeks I've

Re: [swift-dev] Reporting/Debugging Slow Swift Compile Time

Okay great I'll open one soon! And just to clarify, that 2521 number is counting the generated setters and getters (there are fewer number of actual lines of "let" and "var" property code). In the main target, there are 607 .swift files (guess we can deduce that those properties are parsed once

Re: [swift-dev] Reporting/Debugging Slow Swift Compile Time

Hello again! I wanted to follow up with some more numbers and feedback. I wasn't able to easily compile a single file from our project from the CLI. I started putting together a command with all of the necessary framework includes, flags, etc., but I moved on because it was taking awhile, becoming

Re: [swift-dev] Reporting/Debugging Slow Swift Compile Time

I just tried with both Xcode 8.1 beta 2 and Xcode 8.0, and 8.1b2 seems maybe 15s faster (to build our main huge target): 7m28s compared to 7m43s. It's some improvement, but I'm not exactly sure what kind of improvement was expected. Is there any profiling/tracing you all would recommend to help

Re: [swift-dev] Reporting/Debugging Slow Swift Compile Time

I didn't know about that warning, so thanks for sharing that! Having this enabled will help somewhat, at least in terms of keeping specific slow-to-compile functions out of our master branch. That said, I understand Jordan's response (in SR-2741) of being "leery of 'productizing'" these flags.

Re: [swift-dev] Reporting/Debugging Slow Swift Compile Time

Hi Ben, I'd really like to see improvements here as well. I don't know what reports would be useful to the Swift team, but allow me to point out https://github.com/apple/swift/commit/18c75928639acf0ccf0e1fb6729eea75bc09cbd5, which adds a -warn-long-function-bodies option that you may be able to

[swift-dev] Reporting/Debugging Slow Swift Compile Time

Hello! I work with a large project (~900 .swift files and more .m files). We have a nightly job that compiles the app and calls out function bodies (using -debug-time-function-bodies) that are slower than 100ms to compile. Since upgrading to Swift 3, the number of trouble function bodies has one
