ios - Line break in UILabel (Xcode 7 Swift) -

so have array of elements of type float. , have uilabel supposed display each of these elements of array on different lines.

the array is

var history = [float]() 

i used loop go through each element , append uilabel

for(i=0; i<size; i++){         currentstring = string(history[i])         result.text = result.text! + "\n" + currentstring     } 

result uilabel.

i tried using \n doesn't seem recognise it. solutions in swift. in advance!

the first thing check if label has (it stupid mistake, can happen of us)

  label.numberoflines = 0 

assuming true, instead of building string hand, use in-built function join(). sadly, since not string array, can't use directly, have create string array first

  // both storages   var history = [float]() // filled data   var stringhistory = [string]()    // convert each number string   value in history {      stringhistory.append(string(value))   }    // finally, join array 1 string using \n separator   let finalstring = "\n".join(stringhistory) 

hope of helps!
