ios - Swift - Bridging header failed. '*' does not have a member named '*' -

-

i develop app using commoncrypto library. problem can create instance in swift file. object created using objective- c. seems can't create bridging header well.

error message

/users/mnurdin/documents/ios/xxxxx/models/main.swift:15:9: 'customobject' not have member named 'encrypt'

customobject.h

#import <foundation/foundation.h> #import <commoncrypto/commoncrypto.h> #import "gtmbase64.h"  @interface customobject : nsobject + (nsstring*)encrypt:(nsstring*)plaintext withkey:(nsstring*)key; @end

customobject.m

#import "customobject.h" @implementation customobject + (nsstring*)encrypt:(nsstring*)plaintext withkey:(nsstring*)key{     /*--*/     return result; } @end

global.swift

var instanceofcustomobject: customobject = customobject() println(instanceofcustomobject.encrypt("p@$$w0rd","12345678"))

please advice. thank you.

the initial + in declaration indicates that

+ (nsstring*)encrypt:(nsstring*)plaintext withkey:(nsstring*)key;

is class method in objective-c. have call on class (or type in swift linguage) itself, not on instance:

let encrypted = customobject.encrypt("p@$$w0rd", withkey: "12345678")

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
