[tvOS] 'kCTParagraphStyleSpecifierLineSpacing' is unavailable: not available on tvOS

[AndrewBarba]

In TTTAttributedLabel.m I'm getting this error at line 176:

CTParagraphStyleSetting paragraphStyles[12] = {
    {.spec = kCTParagraphStyleSpecifierAlignment, .valueSize = sizeof(CTTextAlignment), .value = (const void *)&alignment},
    {.spec = kCTParagraphStyleSpecifierLineBreakMode, .valueSize = sizeof(CTLineBreakMode), .value = (const void *)&lineBreakMode},
    // 'kCTParagraphStyleSpecifierLineSpacing' is unavailable: not available on tvOS
    {.spec = kCTParagraphStyleSpecifierLineSpacing, .valueSize = sizeof(CGFloat), .value = (const void *)&lineSpacing},
    {.spec = kCTParagraphStyleSpecifierMinimumLineSpacing, .valueSize = sizeof(CGFloat), .value = (const void *)&minimumLineHeight},
    {.spec = kCTParagraphStyleSpecifierMaximumLineSpacing, .valueSize = sizeof(CGFloat), .value = (const void *)&maximumLineHeight},
    {.spec = kCTParagraphStyleSpecifierLineSpacingAdjustment, .valueSize = sizeof (CGFloat), .value = (const void *)&lineSpacingAdjustment},
    {.spec = kCTParagraphStyleSpecifierLineHeightMultiple, .valueSize = sizeof(CGFloat), .value = (const void *)&lineHeightMultiple},
    {.spec = kCTParagraphStyleSpecifierFirstLineHeadIndent, .valueSize = sizeof(CGFloat), .value = (const void *)&firstLineIndent},
};

Commenting out line 176 allows the framework to build properly on tvOS 11
