xcprofiler
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
-
Add
-Xfrontend -debug-time-function-bodiesbuild flags inBuild Settings->Other Swift Flagssection of your Xcode project.
-
Build your project
-
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

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.
