xcprofiler

Build Status Coverage Status Gem Version

Command line utility to profile compilation time of Swift project.

This tool is developed in working time for Cookpad.

Installation

gem install xcprofiler

Usage

  1. Add -Xfrontend -debug-time-function-bodies build flags in Other Swift Flags section on your Xcode project.

  2. Build your project

  3. Execute xcprofiler
$ xcprofiler [PRODUCT_NAME or ACTIVITY_LOG_PATH] [options]

xcprofiler searches the latest build log on your DerivedData directory.

You can also specify the .xcactivitylog.

$ xcprofiler MyApp
$ xcprofiler ~/Library/Developer/Xcode/DerivedData/MyApp-xxxxxxxxxxx/Logs/Build/0761C73D-3B6C-449A-BE89-6D11DAB748FE.xcactivitylog

--show-invalids Show invalid location results
--order -o Sort order (default,time,file)

Use custom reporters

You can use reporters to output tracking logs.

require 'xcprofiler'

profiler = Xcprofiler::Profiler.by_product_name('MyApp')
profiler.reporters = [
  Xcprofiler::StandardOutputReporter.new(limit: 20, order: :time)],
  Xcprofiler::JSONReporter.new({output_path: 'result.json'})
]
profiler.report!

You can also implement your own reporters.

See implementation of built-in reporters for detail.
