Unity cloud build by xcode 7

Guys, I figured it out!

     public class Postprocessor
     {
         [PostProcessBuildAttribute(1)]
         public static void OnPostprocessBuild(BuildTarget target, string pathToBuiltProject)
         {
             BuildTarget iOSBuildTarget;
             #if UNITY_5
                 iOSBuildTarget = BuildTarget.iOS;
             #else
                 iOSBuildTarget = BuildTarget.iPhone;
             #endif
 
             if(target == iOSBuildTarget)
             {
                 setBuildSettingAttrs(pathToBuiltProject);
                 addAppTransportSecuritySetting(pathToBuiltProject);
             }
         }
 
         static void setBuildSettingAttrs(string path)
         {
             #if (UNITY_5 && UNITY_IOS)
                 string pbxprojPath = path + "/Unity-iPhone.xcodeproj/project.pbxproj";
                 PBXProject project = new PBXProject();
                 project.ReadFromString(File.ReadAllText(pbxprojPath));
                 string target = project.TargetGuidByName("Unity-iPhone");
 
                 project.SetBuildProperty(target, "CLANG_ENABLE_MODULES", "YES");
                 project.SetBuildProperty(target, "ENABLE_BITCODE", "NO"); // Disable bitcode to build on cloud    
                 project.AddBuildProperty(target, "OTHER_LDFLAGS", "$(inherited)");
                 project.AddBuildProperty(target, "OTHER_LDFLAGS", "-ObjC");
                 
                 File.WriteAllText(pbxprojPath, project.WriteToString());
             #else
                 UnityEngine.Debug.Log("Unable to modify build settings in XCode project. Build " +
                         "settings must be set manually");
             #endif
         }
 
         static void addAppTransportSecuritySetting (string path){
             // Get plist
             string plistPath = path + "/Info.plist";
             PlistDocument plist = new PlistDocument();
             plist.ReadFromString(File.ReadAllText(plistPath));
             
             // Get root
             PlistElementDict rootDict = plist.root;
             
             // Add NSAppTransportSecurity to plist
             PlistElementDict appTransportDic = rootDict.CreateDict ("NSAppTransportSecurity");
             appTransportDic.SetBoolean("NSAllowsArbitraryLoads", true);
             // Write to file
             File.WriteAllText(plistPath, plist.WriteToString());
         
         }
     }
 }

Place this code into PostProcessor.cs then the file MUST BE placed in Editor folder. It works for me! @Mycroft
