Please add extended support for SF Symbol configuration

[funnel20]

I'm very pleased that InAppSettingsKit version 3.6 now supports SF Symbols via systemImageNamed:.

One question though, as this opens the door to more customisation. In our apps we use even more native power with systemImageNamed:withConfiguration:.
For example to apply palette colouring on a SF Symbol:

// Define image name and configuration:
NSString *name = @"cloud.sun";
UIImageConfiguration *config = [UIImageSymbolConfiguration configurationWithPaletteColors:@[
    [UIColor systemTealColor],      // cloud
    [UIColor systemYellowColor]     // sun
]];

// Create image:
UIImage *image = [UIImage systemImageNamed:name
                         withConfiguration:config];

Since you already use IASKCellImage as name, would it be possible to extend InAppSettingsKit with something like a IASKCellImageConfiguration, which refers to the name of Class variable of the parent ViewController (e.g. config in this example)?

The good part of systemImageNamed:withConfiguration: is that even if config is nil, it will ignore the configuration and just acts as systemImageNamed:.

Thank you for considering this improvement.

This is certainly a good idea. I suggest adding a symbolImageConfiguration property to IASKAppSettingsViewController. That property would have to be copied to all child view controllers (similar to how the delegate is assigned to child VCs). Is probably easier to use, especially from Swift code.

Would you be so kind to contribute a pull request? ;-)

@futuretap I was hoping to apply multiple different Symbol Configurations per ViewController, as the layout might request one configuration per image.
Consider for example the native iOS Settings app, it consists of a wide range of coloured icons:

Hence my idea of a new parameter in the .plist

I see. To achieve this example, you’d need a separate class for each background color. Doesn't really scale well, too.
If I were you, I'd implement the -settingsViewController:cellForSpecifier: delegate callback and set

cell.imageView.image = cell.imageView.image.withConfiguration(yourConfiguration)

Then you can switch on specifier.key to create a configuration per key. Does that work for you?

@futuretap That's a great idea, thank you very much.
