Troubleshooting Objective-C SDK
How to find the version of your iOS SDK
Identifying your SDK version is an essential first step in troubleshooting, as certain issues may be version-specific or already resolved in newer releases.
To find your exact version, do one of the following:
-
In your Xcode project, navigate to PubNub > Misc > PNConstants.h.
-
Alternatively, access it through code:
NSString *version = [PubNub information].version;
