Please use Ruby 2.x.

Add this line to your application's Gemfile:

source "https://rubygems.org"

gem 'zabel'

And then execute:

$ bundle

Or install in local path:

$ bundle install --path vendor/bundle

Or install it yourself as:

$ [sudo] gem install zabel

Simply add zabel before your xcodebuild/fastlane command. Please ensure that your command can work without zabel.

$ [bundle exec] zabel xcodebuild/fastlane ...

You can controll your cache keys, which can be more or less. Please ensure that your arguments are same in pre and post.

$ [bundle exec] zabel pre -configuration Debug ...
$ xcodebuild/fastlane ...
$ [bundle exec] zabel post -configuration Debug ...

Importantly, configuration argument must be set with zabel.

You can customize some options by yourself.

Zabel stores caches in ~/zabel by default. You can change this path.

$ export ZABEL_CACHE_ROOT=xxx

Zabel uses LRU to clear unuse old caches, to keep max count with 10000 by default. You can change this number.

$ export ZABEL_CACHE_COUNT=12345

Zable caches targets which count of source files is greater than or equal 1 by default. You can set this value to 0 or more than 1 to achieve higher total speed.

$ export ZABEL_MIN_SOURCE_FILE_COUNT=10

Zabel detects module map dependecy by default. However, there are bugs of xcodebuild or swift-frontend, which emits unnecessary, incorrect and even cycle modulemap dependencies. Cycle dependency targets will be miss every time. To test by run "ruby test/one.rb test/todo/modulemap_file/Podfile". You can disable this feature.

$ export ZABEL_NOT_DETECT_MODULE_MAP_DEPENDENCY=YES

• 1.0.5 fix script error
• 1.0.4 optimize spec checksums; optimize output log; use CACHE_VERSION; should not cache if dependency error
• 1.0.3 support bundle install
• 1.0.2 support legacy build system
• 1.0.1 support xcodebuild archive and fastlane
• 1.0.0

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Q: Must I set configuration ?

A: Yes, for now.

Q: How to define a cache hit ?

A: A target cache will be hit only when it matches all arguments, settings, sources and dependencies.

Q: What will happen if a cache is hit ?

A: Firstly, PBXHeadersBuildPhase and PBXSourcesBuildPhase and PBXResourcesBuildPhase of a target will be deleted to disable build. Secondly, scripts to extract cache product will be added.

Q: What about scripts ?

A: All original PBXCopyFilesBuildPhase or PBXFrameworksBuildPhase or PBXShellScriptBuildPhase will not be deleted or changed. At most time, they did not take much time. However, they are difficult to be cached.

Q: What about dependencies ?

A: Simple dependent files (headers) and implicit dependent targets will be detected. If dependent files of a target change, this target will be recompiled. If dependent targets of a target miss cache, this target and dependent targets will be recompiled.

• support more projects and targets, not only Pods
• support and test more clang arguments
• support intermediate cache such as .o and .gcno
• try to support local development
• try to support remote cache server
