PyObjus HealthKit support

[Michael]

Hi,

I am trying to make a Kivy app that uses data from HealthKit. The first step is to create a plyer api compatible with healthkit. I am using PyObjus to load the HealthKit.framework and then the autoclass function to load HKHealthStore(https://developer.apple.com/documentation/healthkit/hkhealthstore?language=objc). Once loaded, the only method I can get to successfully work is the isHealthDataAvailable method. All of the other methods fail.

Here is my healthkit.py platform code:

from pyobjus import autoclass, protocol
from pyobjus.dylib_manager import load_framework
from plyer.facades import HealthKitFacades
from pprint import pprint

load_framework('/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/'+
               'System/iOSSupport/System/Library/Frameworks/HealthKit.framework')
HKHealthStore = autoclass('HKHealthStore')


class IOSHealthKit(HealthKitFacades):
    def __init__(self):
        self._healthkit_manager = HKHealthStore
        pprint(vars(HKHealthStore))


    def _method_test(self, **kwargs):
        try:
            print(self._healthkit_manager.isHealthDataAvailable())
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.authorizationStatusForType)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.authorizationStatus)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.getRequestStatusForAuthorizationToShareTypes)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.HKAuthorizationRequestStatus)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.supportsHealthRecords)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.requestAuthorization)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.handleAuthorizationForExtension)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.bloodTypeWithError)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.biologicalSexWithError)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.executeQuery)
        except Exception as e:
            print(e)

        try:
            print(self._healthkit_manager.stopQuery)
        except Exception as e:
            print(e)


def instance():
    '''
    Instance for facade proxy
    '''
    return IOSHealthKit()

And here is the output after running _method_test:

True
'HKHealthStore' object has no attribute 'authorizationStatusForType'
'HKHealthStore' object has no attribute 'authorizationStatus'
'HKHealthStore' object has no attribute 'getRequestStatusForAuthorizationToShareTypes'
'HKHealthStore' object has no attribute 'HKAuthorizationRequestStatus'
'HKHealthStore' object has no attribute 'supportsHealthRecords'
'HKHealthStore' object has no attribute 'requestAuthorization'
'HKHealthStore' object has no attribute 'handleAuthorizationForExtension'
'HKHealthStore' object has no attribute 'bloodTypeWithError'
'HKHealthStore' object has no attribute 'biologicalSexWithError'
'HKHealthStore' object has no attribute 'executeQuery'
'HKHealthStore' object has no attribute 'stopQuery'

I have a feeling that this may be impossible to accomplish with Kivy/Pyobjus because of the complexity of the methods and their calls. Let me know what you think as to why the methods aren't working correctly.

[Robert Flatt]

First check you build what you thought you built:

for e in dir( HKHealthStore):
    print(e)

Second

'requestAuthorization'

If authorizion is involved there may be challenges ;)

Right as you posted that I was in the process of doing it haha. Thank you for your help! Here is the output.

I dont see requestAuthorization

Presumably it didn't get built, try looking at that.

Authorization is a challenging issue, the source may not contain that code.....

[Michael]

It is odd because the docs from Apple say that there should be more methods than what Pyobjus is outputting, such as...

- requestAuthorizationToShareTypes:readTypes:completion:

Requests permission to save and read the specified data types.

[Michael]

Update:

When I run HKHealthStore.alloc().init(), I get a richer set of methods!

[Michael]

If anyone is interested, I will keep posting my progress here with the conclusion hopefully being a pull request. I am going to work on this for a couple of days more, and I am getting less hopefully that kivy/pyobjus will be able to do the job.

Right now I am stuck on the Authorization step(https://developer.apple.com/documentation/healthkit/authorizing_access_to_health_data?language=objc). I have posted all of the methods of each class in rtf format. If y'all have any ideas... plz I need help.
