I believe you need to install the MSGraphClientModels pod file. Let me know if that works.

Hey Thanks - that got the files.... Can you point out where I missed this in the documentation?
How did you figure this out?

When I examine the MSGraphContact class it is not clear how I would assign 'Categories' to this class. Please clarify how that is accomplished using this new class?

Steve

You didn't miss it - we missed it. I just checked, we don't have it mentioned in the readme. I'll add it to the readme.

Regarding setting Categories, it is an NSArray of strings. The setter is defined here: https://github.com/microsoftgraph/msgraph-sdk-objc-models/blob/master/GeneratedModels/MSGraphOutlookItem.h#L13 .

The repo for the models is here:
https://github.com/microsoftgraph/msgraph-sdk-objc-models

There are some great resources here to help you: https://developer.microsoft.com/en-us/graph/get-started/ios

Thanks for your help so far!
I am continuing to use the code snippet I referred to above.
Now that I can build an MSGraphContact I am trying to complete the task per to remainder of the snippet. I am getting an error that does not make sense to me.

It occurs here:
contact = [[MSGraphContact alloc] init];
...
NSError *error=nil;
NSData *contactData = [contact getSerializedDataWithError:&error];

There error is:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Invalid type in JSON write (MSGraphEmailAddress)'

The contact has a single email address constructed like this:
NSMutableArray *emailAddressesList = [[NSMutableArray alloc] init];
MSGraphEmailAddress *emailAddress = [[MSGraphEmailAddress alloc] init];
[emailAddress setAddress:@"tim@apple.com"];
[emailAddress setName:@"Tim Cook"];
[emailAddressesList addObject: emailAddress];
[contact setEmailAddresses:emailAddressesList];

Can you clarify 2 things:

1. why the method terminates rather than report the error?
2. what am I doing wrong in constructing the MSGraphEmailAddress

I am opening this same issue in 'models' GitHub you mention above just to make sure....

@SteveDCronin I see nothing wrong with how you created the contact.

Does NSJSONSerialization.isValidJSONObject(emailAddress) return true?

https://github.com/microsoftgraph/msgraph-sdk-objc-models/blob/af0518ec31da0727b739db9d1b578ffc7f7197d7/BaseModels/MSObject.m#L53

From code:
NSDictionary *emailDict;
emailAddress = [[MSGraphEmailAddress alloc] init];
[emailAddress setAddress:@"tim@apple.com"];
[emailAddress setName:@"Tim Cook"];
NSLog(@"%s emailAddress: %@",func,emailAddress.name);
NSLog(@"%s emailAddress: %@",func,emailAddress.address);
if ([NSJSONSerialization isValidJSONObject:emailAddress]) {
NSLog(@"%s isValid: %@",func,emailAddress);
} else {
NSLog(@"%s isNOTValid: %@",func,emailAddress);
}
emailDict=[emailAddress getDictionary];
if ([NSJSONSerialization isValidJSONObject:emailDict]) {
NSLog(@"%s emailDict isValid",func);
} else {
NSLog(@"%s emailDict isNOTValid",func);
}

From log:
2019-09-10 19:27:29.036826-0700 XYZ] emailAddress: Tim Cook
2019-09-10 19:27:29.892016-0700 XYZ] emailAddress: tim@apple.com
2019-09-10 19:27:44.159134-0700 XYZ] isNOTValid: <MSGraphEmailAddress: 0x2835ae940>
2019-09-10 20:00:47.931312-0700 XYZ] emailDict isValid

Huh?

Michael;

You responded to my question about assigning Categories and the online document mentioned above delineates 'categories' as string collection. I have successfully used the HTTP post mechanism to work around the issues in using the MSGraphContact class.
In the initial testing the assignment of a category seems to be accepted but when I view the newly created contact @ 'https://outlook.live.com/people/' I don't see any category assigned (nor do I see any online means of assigning 'category'...... Is there a limitation with categories that I overlooked somewhere?

@SteveDCronin I'm not familiar with the categories feature. I suggest that you first search on Stack Overflow for the [microsoft-graph] tag and categories. There is already a lot of Q&A for this subject.

Otherwise, post your question to Stack Overflow with the microsoft-graph tag.

I do not understand why the MSGraphEmailAddress is not a valid JSON object. We will need to check whether other complex types are valid JSON objects.

I can tell you that MSGraphPhysicalAddress also fails with the same error.
For now I have given up on using the MSGraph ObjectiveC model objects....
I have succeeded in creating a contact just using JSON formatted text & HTTP Post
