iOS: no icon visible at all (assets seems to be missing?)

[softlion]

🐛 Bug Report

On iOS, material fields don't display any asset. Especially the "delete content" icon on material entries is not displayed. But it is general: there is no icon at all displayed by the library.
The same code does work fine on Android, and all icons are displayed correctly.

Expected behavior

On iOS, MaterialTextField should display the "cross" icon to delete its content

Reproduction steps

Run the existing sample project on an iPhone 6 iOS 12.4 simulator.
Open the text fields test page.

Configuration

Platform:

• 📱 iOS

It seems to be a bug in Sdk Extra.

Also, xf_clear is not available on iOS. There is only an Android resource. So that explains why the clear button won't appear on iOS.

You can solve this problem by manually adding images files in your project. I tried to solve the problem many times, checked everything, project is correct, may be there are problem in dashes in file names. However manually adding all images to your IOS project solves problem. i also compared the library with others existing, where embeded images display correct, didn't noticed any difference

I've PR to add the missing "xf_clear".
@lunjio The setup doc should be temporarily updated to reflect this.
