ios - Why isn't the parameter not passing as ViewController? -


i trying pass viewcontroller parameter, keep getting error. not sure why error occuring. appreciated. enter image description here

class major: uiviewcontroller, uicollectionviewdelegate, uicollectionviewdatasource{  let initial = json.finddetailclass(self viewcontroller, predicate: predicate)   }  func finddetailclass(viewclass: major, @noescape predicate: json -> bool) -> json? {      if predicate(self) {         return self     }     else {         if let subjson = (dictionary?.map { $0.1 } ?? array) {             json in subjson {                  if let foundjson = json.findmultiple(viewclass uiviewcontroller //this error, predicate: predicate) {                     let shorten = foundjson["html"].stringvalue                     print(shorten)                  }              }           }     }     return nil }

if wanna pass viewcontroller parameter, using type parameter type [anyobject].

anyobject likes id in objective-c. can understand type of object of pointer.

func finddetailclass(viewclass: anyobject, @noescape predicate: json -> bool) -> json? ......

and , can convert viewclass real type of object while you're using object.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
