cordova-plugin-googlemaps: cordova-plugin-googlemaps-sdk for IOS support won't install

@fishgrind @battika Thanks, guys.

Glad that it worked for you @fishgrind .

Thanks for all the support and I am closing this issue.

Huge thanks @wf9a5m75 for your help.

@wf9a5m75 Your explanation got me thinking and I replaced Apple Git with Homebrew Git, removed platforms and plugins folder and added the ios platform again and it installed without trouble… Perhaps it was the Git version or as @battika mentioned perhaps an intermittent issue.

Thanks for all the quick support!

Thanks @wf9a5m75 for the explanation it actually makes lot of sense.

The funny thing is it started working for me out of the blue. I was trying to remove/reinstall the plugin and for some reason it installed correctly. I did not make any changes so I switched to another project where it failed before too and attempted to install the plugin. It was successful too. Finally, I created a new project with Ionic, added the IOS platform and this plugin. It worked fine. So, I suppose it was an intermittent issue for me and it works now. I hope rest of the guys can confirm.

On an aside note you can still consider switching back to the old git clone way if the tarball version does not prove to be rock solid on the long run.

Thank you for the attention and dealing with this issue promptly.

this is my package.json:
