Xcode 8 没有将 NSString 分配给 NSInteger 的警告？

Question

For example, I just discovered a bug in my code where I was assigning the result of a method that returns NSString * to an NSInteger .

+ (NSString *)countryDialPrefix;

NSInteger prefix = [CountryCodes countryDialPrefix];

Here are the warnings set for all languages:

This was in "Other Warning Flags" at the Project level:

-w -Xanalyzer -analyzer-disable-checker -Xanalyzer unix

So I removed the -w and that fixed it.
