iOSDFULibrary in a Objective-c project

[fab]

Hi all,

I am trying to add the iOSDFULibrary library to an existing Objective-c project via Cocoapods (Xcode 8.2.1 - target iOS 10).

I have followed the steps reported in the library documentation (iOSDFULibrary on github). This is the output of the "pod install" command:

Downloading dependencies
Using Zip (0.6.0)
Using iOSDFULibrary (3.0.3) 
Generating Pods project
Integrating client project
Sending stats
Pod installation complete! There is 1 dependency from the Podfile and 2 total pods installed.

When I open the Cocoapods created workspace I get the error shown in the picture:

If I convert the libraries, I get a lot of compilation errors. If I otherwise let them untouched, I get this:

“Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.

What is the right procedure to add the library to my project?

P.S.: Everything works as expected in a Swift project but I wouldn't migrate my project to Swift right now just to add the library.

Sorry about that bug, we are currently reviewing what causes this issue, it's quite simple to fix for now.

follow the following steps:

1. Run pod install on your project

2. When Xcode asks to migrate to newer version, select later

3. Select to the Pods target as shown:
   

4. Select the pods project build settings as shown:
   

5. Select Build settings and search for legacy

6. Set Use Legacy Swift Language Version to NO:
   

7. Go through all the other installed Pods and change the same setting to NO on all of them (for example: iOSDFULibrary and Zip in your case

Please follow our github page for iOSDFULibrary for updates on when we find a fix for this bug.

Sorry for the inconvenience!

I followed all the steps you suggested, unfortunately nothing changed.
