iOS8 app crashes on Xcode6.0.1 using HealthKit - ios8

Question

Im actually trying to convert Apple's sample code to swift.
I created an app and an APPID for it in the devcenter. I checked the entitlement for HealthKit (the ones for IAP & GC are greyed and checked automatically).
When the provisioning profile I create for it is downloaded to Xcode and I go into Preferences in Xcode and look at my account's provisioning profiles I can see the name of the profile plus the expiration date and then there are some icons for entitlements. But the provisioning profile I created with HealthKit doesnt have any icon for it, just the 2 default ones, is this normal:
because for some reason the app crashes upon requesting authorization with this error:
2014-10-02 12:16:13.241 SwimFit[549:8824] -[__NSCFConstantString _allowAuthorizationForSharingWithEntitlements:]: unrecognized selector sent to instance 0x107dc1ce0
2014-10-02 12:16:13.251 SwimFit[549:8824] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFConstantString _allowAuthorizationForSharingWithEntitlements:]: unrecognized selector sent to instance 0x107dc1ce0'
If I try to run it on the device I get this:
I have created:
AppId for my app
Activated that AppID for HealthKit
Created Dev provisioning profile for that AppID
Activated HealthKit Capabilities in General
I see the entitlements.plist is created with com.apple.developer.healthkit = yes
The info.plist does have the healthkit value for required capabilities
The only weird thing I did this time and I used to do differently for other apps is that when I clicked on build/run a some point, I let Xcode create an AppID and I get this from devcenter...i cant upload the image but basically all my previous AppIDs are named after the app. This one because its made by xcode is named: Xcode iOS App ID com santiapps SwimFit but its bundle identifier is correct at: com.santiapps.SwimFit. And so is the dev profile: iOS Team Provisioning Profile: com.santiapps.SwimFit and its the one in my Build Settings. Originally I had SwimFit because that was the name of the app so Xcode created an automatic AppID for it with a ProvProfile for it as well. I then thought maybe I should create the appID and provprofile so I did it manually and tried calling it SwimFit2. Both give the same error.
What else could I be missing?
Here is the code:
//1. Add healthstore property
var healthStore: HKHealthStore? //error if not optionally unwrapped
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
//2. Ask for permissions
if (HKHealthStore.isHealthDataAvailable() == true) {
self.healthStore = HKHealthStore() //needs to be var for it to work?
var writeDataTypes = self.dataTypesToWrite()
var readDataTypes = self.dataTypesToRead()
self.healthStore!.requestAuthorizationToShareTypes(writeDataTypes, readTypes: readDataTypes, completion: { (success: Bool, error: NSError!) -> Void in
if (!success) {
NSLog("You didn't allow HealthKit to access these read/write data types. In your app, try to handle this error gracefully when a user decides not to provide access. The error was: %#. If you're using a simulator, try it on a device.", error)
return
} else {
NSLog("success")
}
// Handle success in your app here.
self.setupHealthStoreForTabBarControllers()
})
}
return true
}

I had the same crash yesterday. The problem is that you put the wrong data type (NSString) for the data types into the method.
The requestAuthorizationToShareTypes method requires you to pass a set of HKBaseType objects, in my case HKQuantityType objects.
So instead of:
[_healthStore requestAuthorizationToShareTypes:[NSSet setWithObject:HKQuantityTypeIdentifierBodyMassIndex]
readTypes:[NSSet setWithArray:inputDataTypes]
completion:
Use this one:
HKQuantityType* type = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierBodyMassIndex];
[_healthStore requestAuthorizationToShareTypes:[NSSet setWithObject:type]
readTypes:[NSSet setWithArray:inputDataTypes]
completion:
