I cannot get the integer value from unsafeMutablePointer<32> in swift

Question

I use swift and obj-c classes together in my project.

And I declare this in obj-c header file.

@property (nonatomic, copy) NSString *AppStoreId;

I want to use this obj-c code in my swift class:

NSDictionary *productParameters = @{ SKStoreProductParameterITunesItemIdentifier : [NSNumber numberWithInt:[appItem.AppStoreId intValue]]};

I convert it to swift like this:

var productParameters : NSDictionary = SKStoreProductParameterITunesItemIdentifier(NSNumber.numberWithInt(appItem.AppStoreId))

However, it gives me an error which says "UnsafeMutablePointer < Int32>" is not convertible to "Int32"

I also tried this:

var productParameters : NSDictionary = SKStoreProductParameterITunesItemIdentifier(NSNumber.numberWithInt(appItem.AppStoreId(IntegerType)).intValue)

But this time it gives me an error about using of IntegerType. I don't know what should I do. I am a beginner in swift and objective c. Thank you for any help.

SKStoreProductParameterITunesItemIdentifier is just a key for the dictionary, not a function to create one. You should use:

var productParameters : NSDictionary = NSDictionary(object: NSNumber.numberWithInt(appItem.AppStoreId.intValue), forKey: SKStoreProductParameterITunesItemIdentifier)

you are right, thank you! but how can I get intValue from appItem.AppStoreId? – simge Aug 20 '14 at 10:36
I have written wrong code to get the `intValue`, sorry for that. Now the answer has been edited, all things seem right. – Louis Zhu Aug 21 '14 at 02:53
I cannot find an option like intValue, so I use toInt(). Thank you! – simge Aug 21 '14 at 08:27
