In check swift function:

return ![self vv_isObjCMethod] && ![self vv_isSwiftProperty] && [self vv_matchesPatternRegexPattern:@"^\\s*(.*\\s+)?(func\\s+)|(init|deinit)"];

will do swift property check first in which only var/let is used, so swift function check will fail when var/let type of params is used.

The fix make some change in swift property check:

return [self vv_matchesPatternRegexPattern:@"^\\s*([^(]*?)(((\\s*let|var\\s*)\\s+)|(\\(\\s*set\\s*\\)))"];

because in property declaration, ( appearing before let/var only happens when private(set) or internal(set) is used
