Product:Developer Tools Product Version:Xcode-beta (7A120f)
Classification:Enhancement Reproducible:Always
With the following Swift code:

public enum MyError: ErrorType {
    case Code(code: Int)
    case Message(code: Int, message: String)

@objc public class MyType : NSObject {
    public func throwException(type: Int) throws {
        if type == 0 {
            throw MyError.Code(code: type)
        else {
            throw MyError.Message(code: type, message: "Hello!")
    public func throwExceptionInt() throws -> Int {
        throw MyError.Code(code: 0)
    public func throwExceptionString() throws -> String {
        throw MyError.Code(code: 1)

Only the “throwException” and “throwExceptionString” methods bridge to ObjC.
