Is this patch still relevant? If it is then do you want to rebase it? If it isn’t then you want to close this bug? Patch contains too much magic for me.

> Source/WebCore/platform/graphics/ios/FontCacheIOS.mm:87
> +    if (weight >= FontSelectionValue(350)) {

Where is the magic number 350 coming from? What is the range we’re working with?

> Source/WebCore/platform/graphics/ios/FontCacheIOS.mm:90
> +    } else if (weight >= FontSelectionValue(250))

Such magic.

> Source/WebCore/platform/graphics/ios/FontCacheIOS.mm:92
> +    else if (weight >= FontSelectionValue(150))

Magic

> Source/WebCore/platform/graphics/ios/FontCacheIOS.mm:102
> +    RetainPtr<NSMutableDictionary> traitsDictionary = adoptNS([[NSMutableDictionary alloc] init]);

auto

> Source/WebCore/platform/graphics/ios/FontCacheIOS.mm:123
> +    [traitsDictionary setObject:[NSNumber numberWithFloat:ctWeight] forKey:static_cast<NSString *>(kCTFontWeightTrait)];

@(ctWeight)? @(kCT...)?

> Source/WebCore/platform/graphics/ios/FontCacheIOS.mm:128
> +        [traitsDictionary setObject:[NSNumber numberWithInt:kCTFontItalicTrait] forKey:static_cast<NSString *>(kCTFontSymbolicTrait)];

Similar questions, can we use literal syntax to simplify?

> Source/WebCore/platform/graphics/ios/FontCacheIOS.mm:130
> +    return @{ static_cast<NSString *>(kCTFontTraitsAttribute) : traitsDictionary.get() };

Can we use this syntax for all the unconditional items added to the dictionary and then that just leaves special handing for italic?
