Analysing Assets.car file in iOS

This tool can extract a .car archive: https://github.com/steventroughtonsmith/cartool

Steps to extract archive:

Once you've downloaded the zip from github, compile it in Xcode to generate the command line tool. Then expand the Products group and right click on the cartool file and locate it in finder. You can then run the tool like so:

• open terminal
• cd /path/to/cartool
• ./cartool /path/to/Assets.car /path/to/outputDirectory

It is the "compiled" version of the assets catalog.

How to reference images with different file extensions from XAML?

It is possible to reference images with different file extensions from XAML like this:

<Image>
  <Image.Source>
    <OnPlatform x:TypeArguments="ImageSource">
        <OnPlatform.iOS><FileImageSource File="ic_cup_coffee.pdf"/></OnPlatform.iOS>
        <OnPlatform.Android><FileImageSource File="ic_cup_coffee.png"/></OnPlatform.Android>
    </OnPlatform>
  </Image.Source>
</Image>

Anyhow, this does not solve our issue that the images are sometimes not visible. We stick with using <Image Source="ic_cup_coffee"/> and we will analyze if this bug is the root of the problem.
