Contributions summary:Zayin primarily focused on fixing static analysis warnings within the Google APIs Client Library for Objective-C for REST repository. The commits address issues where pointer values were being converted to boolean values. The changes involved modifying several files, including GTLRDateTime.m, GTLRUtilities.m, and GTLRService.m, to ensure proper comparison with nil or using the boolValue method. These fixes improve code quality and prevent potential runtime errors related to Objective-C code in Google's API client library.
