Command line utility to profile compilation time of Swift project.

This tool is developed in working time for Cookpad.

Installation

gem install xcprofiler

xcprofiler is tested on latest Ruby 2.3/2.4.

Usage

  1. Add -Xfrontend -debug-time-function-bodies build flags in Build Settings -> Other Swift Flags section of 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

Available Options

option shorthand description
--limit -l Limit for display
--threshold Threshold of time to display (ms)
--show-invalids Show invalid location results
--order -o Sort order (default,time,file)
--derived-data-path Root path of DerivedData directory
--truncate-at -t Truncate the method name with specified length
--no-unique Show the duplicated results

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'),
  Xcprofiler::BlockReporter.new do |executions|
    do_something(executions)
  end,
]
profiler.report!

You can also implement your own reporters.

See implementation of built-in reporters for detail.
