CoreText: Fix getting system fonts on recent macOS/iOS versions
We introduced a work-around for iOS 11 which breaks on more recent OS versions because we try to request meta-fonts by name instead of using the special system font descriptors. This would cause warnings on the console and Times New Roman when requesting e.g. the system fixed width font. When testing on iOS 12 without the work-around, we are no longer able to reproduce the original issue, so the assumption is that this problem has been resolved. Since iOS 11 is not a supported target for Qt 5.14 we can remove the work-around entirely. [ChangeLog][macOS/iOS] Fixed a bug where QFontDatabase::systemFont() would return the wrong fonts on macOS 10.15 and iOS 13. Fixes: QTBUG-79900 Change-Id: Ie375c8c2ab877d6d66e3696662c4939f639a6e9e Reviewed-by: Tor Arne Vestbø <>
