Xcode 7 suppress deprecated warnings

For compatibility I regrettably need to use methods that were deprecated in iOS 9, and it generates warnings that I am not able to suppress after 15 hours of trying. Example: 

'CFWriteStreamCreateWithFTPURL' was deprecated in iOS 9.0: Use NSURLSessionAPI for ftp requests'

I have tried:

  1. project>target>Build Phases>click on appropriate file, and select flag -w
  2. project>target>Build Phases>click on appropriate file, and select flag -(specific flag for error)
  3. project>project>Build Settings>Apple LLVM 7.0 - Warnings - All Languages>Depreciated Functions> No
  4. project>project>Build Settings>Apple LLVM 7.0 - Warnings - Objective C>Overriding Depreciated Objective C Methods>No
  5. tried finding pragma alternative but it looks like it is not possible
  6. Edit: I need to use depreciated methods regardless of what OS version is on device

I can suppress warnings in ObjC, but it just doesn't seem to work in Swift 2.0 and I have to admit that it's starting to really bug me, I know that I have to use different methods eventually, but right now it is not possible.

How do you suppress warnings in Xcode 7/Swift 2?

Solution

  • I was the one who asked the question above, and if anyone is here looking for the answer to the same problem here is what I have found so far: point 1-6 are not effective in swift because there is no precompiler. (if that is really the case i wish apple would have warned me when I tried to use -w)

    if you really do need to use deprecated methods and are unwilling to put up with the warnings it generates then you can add that part of your code as a framework and compile that part of your project for a previous OS version. It would be better to not use deprecated methods at all! http://www.rockhoppertech.com/blog/swift-framework-creation/

    I hope this is helpful to someone, and if it is wrong then please tell me why and how below :)
