Swift Niceties

This is a collection of Swift extensions and classes/structs/enums for those that are familiar with Java method calls, and want to be able to use them, whilst they transition to using Swift in more depth.

There are two parts

Extensions

Extension extend the functionality of existing swift classes

Replacement Classes

Where a class with an identical name exists in Swift, the class and functionality in SwiftNiceties is prepended (or namespaced with SN. E.g. SNCalendar is a new class, rather than extending the swift Calendar class.

This is NOT a bad idea

Yes, you should probably learn swift and do all of the convoluted things that swift wants you to do, but there are times when this is overly burdensome.

There are also times where the

Some examples

Getting a random number between 0 and 4

in Swift

let randomInt: Int = Int.random(in: 0..<5);

in SwiftNiceties

let randomInt: Int = Random.nextInt(5);

in Java

Random random = new Random(System.currentTimeMillis());
int randomInt = random.nextInt(5);

Adding components to dates

in Swift

var date: Date = Date()
var dateComponent = DateComponents();
dateComponent.day = 1;

date = Calendar.current.date(byAdding: dateComponent, to: date)!;
print(date.timeIntervalSince1970);

in SwiftNiceties

var calendar: SNCalendar = SNCalendar.getInstance();
calendar.add(SNCalendar.DAY_OF_MONTH, 1);
print(calendar.getTimeInMillis);

in Java

Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.DAY_OF_MONTH, 1);
System.out.println(calendar.getTimeInMillis());
