fatal error: call of removed method

Hi,

Does anyone have any clue about this error message?

fatal error: call of removed method

I am getting this crash from Xcode after trying to use a Class function from a custom framework made in Swift.

Setup is as follow

public protocol Something { 
  var prop1: String   { get } 
  var prop2: [String] { get } 
  var prop3: [String] { get } 
  ... 
} 

public class Things { 
  public class func stuffWithName(name: String) throws -> Something { 
       return try Stuff(name: name) 
  } 
} 

struct Stuff: Something { 
  let prop1: String 
  let prop2: [String] 
  let prop3: [String] 

  init(name: String) throws { 
     ...do stuff... 
  } 
}

Things.stuffWithName("Sockets")

This works perfectly in Unit Testing but crash when the framework is used within an App.

The weirdest is that I have other objects using the exact same architecture and they don't crash.

Any clues where I could dig further?

Cheers
