func oneStepForward(_ input: Int) -> Int { return input + 1 } func oneStepBackward(_ input: Int) -> Int { return input - 1 } func chooseStepFunction(backward: Bool) -> (Int) -> Int { return backward ? oneStepBackward : oneStepForward //Error. type of expression is ambiguous without a type annotation } Why am I getting this error ? If I change this function to the following it works and will compile. func chooseStepFunction(backward: Bool) -> (Int) -> Int { if backward { return oneStepBackward } else { return oneStepForward } } // Why am I getting the error in the previous version while it works in the second version ? Thx in advance.

Greetings, func stepForward(_ input: Int) -> Int { return input + 1 } func stepBackward(_ input: Int) -> Int { return input - 1 } func chooseStepFunction(backward: Bool) -> (Int) -> Int { return backward ? stepBackward : stepForward /* Error type of expression is ambiguous without a type annotation */ } Why am I getting this error. If I change the function to func chooseStepFunction(backward: Bool) -> (Int) -> Int { if backward { return stepBackward else { return stepForward } } Why is the previous chooseStepFunction giving me an error ? Thx in advance

I really like the swift color syntax in the editor window of Xcode . The trouble is it constantly stops working . I have to choose the swift color syntax from the menu to get it to work again . Works for a short (Very short) while and then stops working again . Very annoying . Also the live error reporting in the swift editor window (which I also like very much) of the Xcode IDE constantly stops working . I have to quit Xcode (Usually force quit) and restart it to get it working again . Very annoying . Xcode has been out for many years now and I am sure Apple is pouring a lot resources into it . These constant bugs (which hit you right in the face) should have been resolved by now. They have no excuse .
