Hi Abdiel,

When you try to generate in IOS with MABS 6.3/7.0 there are 4 errors:

This plugin uses https://github.com/LuisMAlmeida/cordova-plugin-tts (version forked from https://github.com/vilic/cordova-plugin-tts). These versions in the IOS source (src/ios/CDVTTS.m) have a redefinition of variables problem that does not allow to compile in IOS.

Options

1. You can wait a fix in cordova plugin https://github.com/LuisMAlmeida/cordova-plugin-tts (the version of Vilic Vane is discontinued).
2. Change the plugin to reference other cordova plugin (for example https://github.com/spasma/cordova-plugin-tts-advanced/) and make little changes in plugin.
3. Search other speech plugin. :-(
4. Download https://github.com/LuisMAlmeida/cordova-plugin-tts, make changes in code, generate the .zip and reference it in the plugin (https://success.outsystems.com/Documentation/10/Extensibility_and_Integration/Mobile_Plugins/Using_Cordova_Plugins#Referencing_Cordova_Plugins).

The best option is 1 but perhaps the team of this plugin can give you more information.

Kind regards, David.
