Answer 1

I had the same problem and solved it by painstakingly going through my code line by line, it turns out Swift 3 prefers string interpolation rather than using the + symbol, i.e.

let url = "http://yahoo.com" + "someWebPage" + "whereItsInteresting" 

If you have been using the above style of code replace it for;

let url = "http://yahoo.com\(someWebPage)\(whereItsInteresting)"

And your build time will immediately come back to normal.
