The marked question does not explain how to solve the string concatenation issue ...Is there a replacement for the '+' operator ? – techno Oct 09 '17 at 11:38

Did you try string *interpolation* (as suggested in an answer to the referenced question)? – Martin R Oct 09 '17 at 11:48

1@MartinR For any one who might come across this question.This is a compiler issue with swift to do with '+' operator overloading.This can be solved by string interpolation e.g.:`var data="data1=\(value1)&data2=\(value2)&data3=\(value3)"` – techno Oct 09 '17 at 11:50

That is exactly what this answer https://stackoverflow.com/a/39514629/1187415 suggests: *"concatenating strings with interpolation ... is much better than ..."* – why do you think that it is not a duplicate or should be reopened? – Martin R Oct 09 '17 at 11:58

@MartinR That is a lengthy explanation and does not directly show an example to solve this ie:String Interpolation.I think an example would be helpful for beginners like me. – techno Oct 09 '17 at 12:00
