I have encountered places where NSTaggedPointerString cannot be used as a NSString, such as when creating an NSDictionary. In those cases use stringWithString::
NSTaggedPointerString
NSString
NSDictionary
stringWithString:
NSString* <# myNSString #> = [NSString stringWithString:<# myNSTaggegedString #>];
