No such module Common Crypto

Question

I am working with swift 3.2. I have made a bridging header file which has the following:

#import <CommonCrypto/CommonCrypto.h>

In my projects build setting I am pointing to my bridging header file but i am still getting the error 'No such module CommonCrypto' in my classes where I am using import CommonCrypto

update: header file:

#ifndef ProjectName_Bridging_Header_h
#define ProjectName_Bridging_Header_h

#import <CommonCrypto/CommonCrypto.h>

#endif

can you show your entire bridging header, I imported common crypto the exact same way you did and mine is working fine — TNguyen, Oct 23 '17 at 16:45
Have you tried [this](http://iosdeveloperzone.com/2014/10/03/using-commoncrypto-in-swift/)? — Daniel, Oct 23 '17 at 17:00
you don't need to do `import CommonCrypto` if you already have it in your header file. You can just use it straight — TNguyen, Oct 23 '17 at 17:08
@TNguyen if I remove import CommonCrypto then I get warnings saying 'use of unresolved identifier CommonCrypto' — user2363025, Oct 24 '17 at 08:29
Previoulsy I had commonCrypto in a framework and had used an aggregate. With that I needed to import CommonCrypto and use it like CommonCrypto.kCCOptionPKCS7Padding for example. I removed all my 'CommonCrypto.' references from my swift file and it worked- thanks for the help! — user2363025, Oct 24 '17 at 09:33

I've found the workaround to make Xcode be able to find CommonCrypto via Swift module as stated here by Mihael Isaev.

I used such approach in my project (Xcode 9.3, Swift 4). I summarize steps as follows.

Create a new directory namely CommonCrypto at the root of your project (or for me I created it at the same level of AppDelegate.swift file)
Create a file name module.map inside that directory (done outside Xcode) with following content
```
module CommonCrypto [system] {
   header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/CommonCrypto/CommonCrypto.h"
   export *
}
```
If you install Xcode elsewhere, you can manually find location of such .app yourself then append it with /Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/CommonCrypto/CommonCrypto.h or you can execute xcode-select -p to get the path of Xcode then append it with /SDKs/iPhoneOS.sdk/usr/include/CommonCrypto/CommonCrypto.h
Go to Build Settings in Xcode then search for swift compiler - search paths.
Enter $(PROJECT_DIR)/<project name>/CommonCrypto into its Import Paths in which <project name> is your project name.
Now you will be able to build the project, and Xcode would find such module.

Note: No need to add such CommonCrypto directory which hosts module.map file into Xcode via Add Files to .... It only used in compilation step thus no problem there.

are you using rave framework ? inside commoncrypto module what has to be the path in my case `.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/CommonCrypto/CommonCrypto.h` where the commoncrypto is should i replace this ? — Midhun Narayan, Dec 11 '18 at 10:47
