Keep in mind that everything you need to do can also be accomplished with any modern smartphone running iOS or Android. There are numerous low cost or free apps available that can record points and output them in GPX format. Use software like the previously mentioned DNRGPS to convert the GPX points to shapefile, or use the GPX import tool in ArcToolbox. For iOS I've had great luck with GPS Kit. iOS devices (and many Android devices) use both GPS and GLONASS satellites and seem to collect data on par with most Garmin-type consumer GPS receivers. I'm not as familiar with Android, but I'm sure there are others on these forums that can recommend equivalent software.

Somehow [AGSGDBFeatureTable canUpdateFeature:feature] kicks off a traverse of the entire featureTable (or possibly the entire GDB). So what you would expect to be a quick boolean check before updating a feature can stall the app for minutes while it searches through large feature layers. Avoid using this. Matt Cooper‌

Pretty much. We started using our own IDs before the offline geodatabase was a thing and we were having to use our own offline framework (and juggle JSON files). Once the .geodatabase came into being we tried transitioning to use the built in relationship functions, but we were unable to successfully edit related records without getting weird errors. So we reverted to our old ID fields and haven't looked back. All our db and web stuff use those ID fields rather than GlobalID. Since our primary keys are built from device name and time stamp they have a nice side effect of giving us some additional information about the record that has come in handy once or twice.

In our case we use our own primary key fields to perform this function. For instance: when creating a new related feature the user clicks an "add" button on a form and a new view is generated... at that time the foreign key attribute linking the feature to the parent record is populated and a new primary key value is generated from the current date/time.

Pretty much - you'd have to get a bit creative if you want to include them - like embedding the caption info into the EXIF/IPTC tags when it is collected or adding a field to the attachment table somehow. I would consider using a camera app like Photogene2: Photogene² for iPhone on the App Store on iTunes It allows you to edit the IPTC tags for a photo, add a caption, and then export to the photo library. You could then import the photo as the attachment. I haven't had a chance to test it to see if the IPTC data makes it through the sync process.

I think if you want to use the globalID fields you should be managing the relationships and records using ESRI's built in functions like queryRelatedFeaturesWithParameters. As far as I can tell Global IDs are indeed inaccessible. That said we've had a lot of trouble using the built in relationships in offline geodatabases... read about our woes here: GlobalID error when saving edits to offline geodatabase‌ For now we are maintaining our own relationships and IDs without using GlobalID - it really isn't that much more complicated to just pass in an ID and execute a normal query. We build our IDs using the device name and a date/time stamp to keep things unique

That's correct - I think the best you could do would be to add a caption field to the feature you are assigning the attachment to. We've had to implement this as a custom feature using the Runtime SDK

The geodatabase was created using the desktop workflow. Using 10.2.2 I'd be happy to share it with you - let me know how best to send it.

I was able to work around this issue by creating a grid over the extent of the layer in ArcMap and using the Split Polygons tool to chop everything up. This didn't solve the problem - multipart geometry still doesn't draw correctly, but it did reduce the number and size of multipart features so they are less noticable. You could also use the dice tool to do this. It appears that this is a bug in either the offline geodatabase or the SDK drawing routines.

We've got 2 iSXBlue II units out in the field this summer - so far we've been seeing ~0.7m accuracy. Since it uses SBAS I was worried we would loose the correction signal when we got too far north (survey running up to the North Slope in Alaska) but so far no issues.

I've got an issue with a large polygon feature layer (~20,000 features). In the screenshot below you can see a landcover layer. It appears that the polygon features with multipart geometry are not drawing correctly. The area in the image with the crisscross lines should all be a single feature surrounding smaller features of different types. I've tried various repair geometry and simplify tools with no effect. If I look at the geometry in ArcMap (view sketch) it seems like everything is in the correct order. It's almost as if the breaks between the multiple parts of the geometry aren't being passed into the runtime geodatabase. Has anyone had any experience with complex geometries in the runtime geodatabase? Matt Cooper‌

Should have mentioned that this is running SDE against SQL Server.

Using feature services to create a check-out database for iOS Runtime. I noticed that if I try to query the feature services using the getdate() function it fails in 10.2.2 where it worked fine in 10.1 or earlier. For example - executing a query against the REST endpoint for a feature layer with an AGSDate field using "WHERE dateField > getdate() - 7" will return all records with a date value within the last 7 days. Works like a charm in 10.1, fails with an error in 10.2 Is this a known bug? Matt Cooper‌

I think that setting controls the ability to edit through the AGOL web map. An iOS app would be using the feature services directly, and can make changes to any service that allows edits.

This is why storyboards drive me nuts - you can't diff a storyboard file (or a xib for that matter). This makes any sort of collaborative development using a repo very difficult.
