iOS FITDeveloperField - Unable to add string values

Hey.

I'm having difficulties with the FIT Objective-C SDK when trying to create an Activity file.

I need to add a couple of DeveloperFields to Laps and Sessions.

First I define a FITFieldDescriptionMesg, add a field name and unit and set the FitBaseTypeId to FITFitBaseTypeString.

After creating an actual FITDeveloperField from it, I'm noticing that its "AddValue" function only takes an NSNumber class. Since I'm able to define the FieldDescription as a string, I would expect that I would be able to write a string value in it, as well.

My teamates on Android have no issues with this, since their value property is of type Object and can store pretty much anything. Why is iOS limited to numbers or am I missing something?

The FIT Objective-C SDK is a thin wrapper on top of the FIT C++ SDK; and AddValueForIndex and getValueForIndex were the only two methods exposed in the Obj-C Developer Field wrapper class for the underlying C++ Developer Field class. The C++ class does have get/set string value methods. Exposing those methods in theory is doable, but we need to give it a try to be certain. We will triage this in the coming weeks.

Yes, I noticed the same. I already created methods to add strings in my local SDK copy and if you wish I can create a PullRequest on you SDK repository for you to take a look at.

It also includes some fixes regarding developer fields in the C++ layer, which was reported here: Decoding fails when using string type developer field [FIT SDK C++]

If you create a PR we can take a look at what you did, but we can't merge it. The GitHub repo is just where we publish the SDK to. So we need cherry pick the changes into an internal repo.
