How to check/cast class to generic type with where in Swift -

i came with simple playground illustrating problem:

import uikit  protocol myprotocol {     var foo: bool { set } }  class mygenericclass<t: uiview t: myprotocol>: uiview {}  func checkifismygenericclass(view: uiview) -> bool {     return view mygenericclass // generic parameter 't' not inferred } 

i need identify instances of mygenericclass.

my actual code isn't simple, please don't ask me change mygenericclass declaration.

mygenericclass has associatedtype requirements. not sure try

import uikit  protocol myprotocol {     var foo: bool { set } }  class mygenericclass<t: uiview t: myprotocol>: uiview {}  func checkifismygenericclass<t: uiview t: myprotocol>(view: t) -> bool {     return view mygenericclass<t> // generic parameter 't' not inferred } 

updated

import uikit  protocol myprotocol {     var foo: bool { set } }  class view: uiview, myprotocol {     var foo: bool = true }  class mygenericclass<t: uiview t: myprotocol>: uiview {      var variable: t!      init() {         super.init(frame: cgrectzero)     }  }  let view = view() let obj = mygenericclass<view>() obj.variable = view let anyotherobj = uiview()   func checkifismygenericclass<t: uiview t: myprotocol>(view: uiview, type: t) -> bool {     return view mygenericclass<t> }  checkifismygenericclass(obj, type: view) // returns true checkifismygenericclass(anyotherobj, type: view) // returns false
