I know the IOS SDK claims to be compatible with FMGo 15.0.4, but I have noticed some of the pre 15.0.4 type crashes during calls to access the camera in the equivalent SDK App. So, is the Go engine really 15.0.4 based? A solution which works perfectly with FMGo, fails when deployed as a FIAS App, specifically when the camera is called or an attempt is made to replace an image in a container field with an image in the photo album using the App extension feature. If it isn't based on 15.0.4, when is the IOS SDK likely to be updated? A rhetorical question perhaps but, if it is the Go engine at fault, SDK is a non-starter in its current form.
