When trying to assign a regular string literal to an Objective-C 'id' type or a pointer to an NSString, emit a code insertion hint that turns it into an Objective-C string. For example:
@class NSString;
@interface Test
+ (void)test:(NSString *)string;
@end
void g(NSString *a);
void f() {
NSString *a = "Foo";
g("Foo");
[Test test:"Foo"];
}
will produce
t.m:10:17: warning: incompatible pointer types initializing 'char [4]', expected 'NSString *'
NSString *a = "Foo";
^~~~~
@
t.m:11:5: warning: incompatible pointer types passing 'char [4]', expected 'NSString *'
g("Foo");
^~~~~
@
t.m:12:14: warning: incompatible pointer types sending 'char [4]', expected 'NSString *'
[Test test:"Foo"];
