The document compares and contrasts Swift, Objective-C, and C# programming languages. It discusses how arrays and functions are defined in each language, and it promotes Swift's use of playgrounds for testing code. It concludes by providing further resources for learning Swift such as Apple documentation, online communities, and WWDC sessions.

1. Swift

2. Objective C

3. Objective C without the C

4. C# with Cocoa

5. C# vs Swift – Arrays
●
Objective C
NSArray *myArray = [[NSArray alloc]
init];
NSArray *myArray = [[NSArray alloc]
initWithObjects:@"one", @"two",
@"three", nil];
●Swift
var myArray = String[]();
var myArray = [“one”, “two”, “three”];
●C#
var myArray = new string[];
var myArray = new []{“one”, “two”,
“three”};

6. C# vs Swift - Functions
●
Objective C
- (string)sayHello:(string)name
{
// do something
}
●C#
st ri ng sayHello(st ri ng name) {
// do something
}
●Swift
func sayHello(name: String) -> String {
// do something
}
