**Description**  
I added ZoomVideoSDK framework to my project. After I build it I get a couple of warnings from the compiler. It says:  
“Pointer is missing a nullability type specifier (\_Nonnull, \_Nullable, or \_Null\_unspecified)”  
There are two functions with these warnings: subscribeWithDelegate and unSubscribeWithDelegate, they are located in ZoomVideoSDKRenderer.h. Did anybody run into the same?

**Which iOS Video SDK version?**  
1.3.2 but the same warnings were in 1.3.1

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:

1. Add ZoomVideoSDK framework to project
2. Build
3. Open issue navigator in Xcode
4. See warnings
