Swift 5.2 support (Xcode 11.4) #668
Description
Macaw doesn't compile with Swift 5.2 included in Xcode 11.4 beta 1.
There are 4 compilation failures that I saw. This was in Gradient.swift:
Error message:
Overridden method 'equals' has generic signature <T where T : Gradient> which is incompatible with base method's generic signature <T where T : Fill>; expected generic signature to be <T where T : Fill>
Perhaps as a workaround to this to change the T: Gradient up to the expected T: Fill and the guard on the first line to cast it to the expected type, else false:
// Before:
override func equals<T>(other: T) -> Bool where T: Gradient {
...
}// Suggestion:
override func equals<T>(other: T) -> Bool where T: Fill {
guard let other = other as? Gradient else {
return false
}
...
}
