'NSNumber' is not convertible to 'Int' Swift -

i trying math set position of shape node. looks (swift): var score: nsnumber? score = score! + 1

xcode 6 beta 5 run perfect, xocde 6.1 not run, study 'nsnumer' not convertible 'int'

i realize older question, , have figure out already, having similar issues myself recently, figured i'd post reply posterity.

swift (as far know) still undergoing design changes programming language, , 1 thing noticed needed start wrapping int's within int() function. illustration might need this:

class="lang-c prettyprint-override">var score: nsnumber? score = nsnumber(integer:score!) + 1

edit:

to seek , explain why need this, believe, because score nsnumber(), can have various numeric forms. nsnumber(integer:score!) re-wraps score! integer specifically, allowing utilize integers against in math equations.

int nsnumber
