ios - How to conform to an objective c protocol in an existing .h file in Swift? -


i trying recreate ray wenderlich tutorial in swift, using both swift , objective c. main part (i.e. view controllers , models) done in swift , using bridging header existing .h , .m classes.

i having trouble trying swift view controller conform obj-c delegate.

in .h file have:

@class rwtrateview;  @protocol rwtrateviewdelegate - (void)rateview:(rwtrateview *)rateview ratingdidchange:(float)rating; @end @interface rwtrateview : uiview ... @property (assign) id <rwtrateviewdelegate> delegate;  @end

in swift file have:

class detailviewcontroller: uiviewcontroller, uitextfielddelegate, rwtrateviewdelegate, uiimagepickercontrollerdelegate, uinavigationcontrollerdelegate {  @iboutlet var rateview : rwtrateview ...     func configureview() {             // update user interface detail item.             if let detail:rwtscarybugdoc = self.detailitem as? rwtscarybugdoc {                 if let rv = self.rateview {                     rv.notselectedimage = uiimage(named: "shockedface2_empty.png")                     rv.halfselectedimage = uiimage(named: "shockedface2_half.png")                     rv.fullselectedimage = uiimage(named: "shockedface2_full.png")                     rv.editable = true                     rv.maxrating = 5                     rv.delegate = self rwtrateviewdelegate                     rv.rating = detail.data.rating!                     self.titlefield.text = detail.data.title                     self.imageview.image = detail.fullimage                 }             }         }     ...      func rateview(rateview:rwtrateview!, ratingdidchange rating:float!) ->void {          if let detail = self.detailitem as? rwtscarybugdoc {             detail.data.rating = rating         }     }  ... }

for reason, i'm getting error message saying type 'detailviewcontroller" not conform protocol 'rwtrateviewdelegate' , i'm not quite sure why.

the full code @ https://github.com/dwmchan/scarybugsswift.

would appreciate feedback on because i've spent last 3 days looking answers online couldn't find on this.

you have: 

func rateview(rateview:rwtrateview!, ratingdidchange rating:float!) ->void {

my xcode 6 (beta 2) autocompletes line 

func rateview(rateview: rwtrateview!, ratingdidchange rating: cfloat) {

note second parameter's type cfloat, not float!.
