+# flatter
+
+Faced with similar problem?
+
+> 🚨 `error: unable to spawn process (Argument list too long)`
+
+Until [Apple not fix it](http://www.openradar.me/35879960) I made some solution for workaround this problem - flatter!
+
+Flatter is a gem which move all swift files in xCode project to root group. That's all :)
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'flatter'
+```
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install flatter
+
+## Usage
+
+Simple
+
+    $ flatter "/path/to/your/project.xcodeproj"
+
+Specific group
+
+    $ flatter "/path/to/your/project.xcodeproj" -g "SpecificGroup"
+
+Advanced
+
+    $ flatter "/path/to/your/project.xcodeproj" -g "SpecificGroup" -e ".xib"
+
+## Contributing
