Use of association types in the Ios-swift protocol

Associated Type: Association type

Sometimes it comes to the requirement that classes that inherit from a protocol need to ensure that the type of arguments handled by the proxy method is consistent, which requires the use of Association types to do so

Agreement statement:

Protocol Atypedelegate {

Associatedtype T

Func printcontent (ct:t)

Func Colum (ct:t)

}

Protocol use:

Class Atypeclass:atypedelegate {

Typealias T = Int

Func printcontent (ct:int) {

Print ("Int", #function)

}

Func Colum (ct:int) {

Print ("Int", #function)

}

}

Atypeclass inherits from Atypedelegate, the concrete type of T must be defined in the Atypeclass class in order to use
