CharacterSet.whitespaceAndNewlineCharacterSet())
.filter({func split() -> [String] {
return self.components(separatedBy: .whitespacesAndNewlines).filter{!##代码##.isEmpty}
}
!= ""});
}
}
extension Array {
func unique<T: Equatable>() -> [T] {
var uniqueValues = [T]();
for value in self {
if !contains(uniqueValues, value as T) {
uniqueValues.append(value as! T);
}
}
return uniqueValues;
}
func first<T>(test:(T) -> Bool) -> T? {
for value in self {
if test(value as! T) {
return value as? T;
}
}
return nil;
}
