Weird topic. Maybe you should show your error & explain in detail what you have done so far?

    // Code Injection example
    if(GetPrefBool(@"key1")) {
      vm_writeData(0x016BB4F4, 0x200080D2); // 
    }
}

This for example i make it to try to make tweak.mx file but can’t make package always error I don’t know if i make it correctly , i know how to chenge it in binary but can’t make tweak , offset 016BB4F4 hacked hex 200080D2C0035FD6

You are using the openURL function for iOS 10+ SDK. By your errors, I see you have the iOS 9 SDK so replace them with:

[[UIApplication sharedApplication] openURL: [NSURL URLWithString: @"https://example.com"]];

Or you can use an SDK with version >= 10. Have a nice day!
