As you may know Apple no longer accepts applications created with a technology produced by the PhoneGap build (UIWebView). It requires using an alternative technology called WKWebView not supported by PhoneGap at the moment.

Unfortunately it seems that PhoneGap is in the maintenance mode and is no longer supported by Adobe. So PhoneGap build cannot be used anymore and an alternative vendor that supports WKWebView must be used for iOS applications.

One vendor that can be used is Monaca (monaca.io). Another one is ionic (https://ionicframework.com/)

In the new version that we are working on, Aware IM will produce the .zip file that can be directly imported into Monaca and which will work with both iOS and Android phones. In the meantime if you need to build iOS applications using the current Aware IM version, you need to do it yourself.
Here is what you need to do:

Create an account with Monaca
Import a zip file created by Aware IM for PhoneGap into a Monaca project (read Monaca doco how to import a PhoneGap file)
Open the project using Monaca IDE
Re-arrange the structure of the project files to conform with Monaca project requirements:
a) Create a new folder called “www” (if not created already by Monaca)
b) Create a new folder called “res” (if not created already by Monaca. This folder will contain all you images used in your app.
c) Move all of the files EXCEPT the config.xml file into the www folder
Replace the config.xml file with the attached one
Modify the attached file to include your icons (alternatively, add your icons using Monaca IDE) and your server (instead of YourServer.com)
Replace index.html with the attached file. Make your custom changes to this file - replace YourServer.com and other changes if required
Go to the Build/Build Environment Settings menu item and click on iOS 5.1.1
Go to Configure/App Settings for iOS and make sure that WebView engine is set to WKWebView
Perform build for iOS and Android
