I just released my iOS app updated to Dropbox API v2 using the Obj-C library through CoCoPods. I works fine in iOS9. But now I am getting calls that it crashes on start-up under iOS8.x. Then I ran an iOS simulator with iOS 8.4 and it does indeed crash on start-up with
dyld: Symbol not found: _NSURLSessionTaskPriorityHigh
A search of the source code shows this appears in only one place, in the Dropbox file DBTransportClient.m. The Obj-C library was supposed to be compatible with iOS8 and above. What should I do?
By the way, I commented out the offending line in DBTransportClient.m and my app started up without errors.
