swift - How to install XCGLogger? -

i want add xcglogger framework project.

at xcglogger github page "how use"-section , demo project. tasks not quite clear me. therefore questions:

1. "add xcglogger project subproject project" - mean drag "library"-folder project folder in project navigator?
2. "and add either ios library dependancy of target(s)" - how doing that?
3. what have @ product->scheme->edit scheme ... menu? because don't want framework in release build.
