what is the usage of “~>” in cocoapods
问题 I want to know what the "~>" is used for,cause I find they are the same below: pod 'AFNetworking','~> 2.0.3' pod 'AFNetworking','2.0.3' 回答1: Well, ~> (the optimistic operator) is used when you want to specify a version 'up to next major | minor | patch '. For example: ~> 0.1.2 will get you a version up to 0.2 (but not including 0.2 and higher) ~> 0.1 will get you a version up to 1.0 (but not including 1.0 and higher) ~> 0 will get you a version of 0 and higher (same as if it was omitted)
