ios - Int is not convertible to UIint32 error -

i new swift , xcode , need help. have function gets integer variables. , when use them give me errors. here code

func checkthenumber(range: int, numberofguesses: int) { var randomnumber = int(arc4random_uniform(range) + 1) numberofguesses-- when try use range variable says "int not convertible uiint32" , when try use number of guesses says "unary operator cannot applied operand of type int"

change :

 var randomnumber = int(arc4random_uniform(uint32(range)) + 1) 

you have cast int uiint32
