randomTemperature variable error in x Code

Currently I am running xCode version 7.0.1 If anyone has encountered the error: "Cannot call value of non-function type 'UInt32' " while copying Pasan's randomTemperature variable as seen below:

import Foundation

var randomTemperature = Int(arc4random_uniform(UInt32(150)))

The following code will eliminate the error:

import Foundation

var randomTemperature = Int(arc4random_uniform(150))

Like Pasan said, don't worry to much about the specifics of this code. Just know he will explain it in greater detail at a later time and you can continue your playground error free.

This problem might be caused by some mistake I made earlier in my code, however I figured I would post the solution in case anyone else runs into the same error.

I have used the syntax that Pasan used and no error occurred. Im using Xcode Version 7.1 (7B91b).

It may have just been a minor mistake on my end somewhere in the code. I know 7.1 had a few bug fixes, maybe that was one of them?

Maybe you have an error in your code, you have to be careful because XCode doesn't have a good explanation and identification of errors, most cases XCode says incorrect things. PD: Here i have to say that C#(Visual Studio) is pretty good on Error identification.

I found if I manually type the whole line exactly as it is supposed to be that it works but if I use the autocompletion to fill in the line in XCode that it generates errors and has different formatting. Just type it as Pasan has it manually and it should work.
