Hey Terrez, I'll give it a go:

'Float' and 'Double' are both variable definitions for decimal numbers. Float is 32-bit while Double is 64-bit, which means Double can cope with larger digits.

'Self' refers to the property or method of a class. A class consists of two files 'header (.h)' and 'implementation (.m)'. The header defines public variables and methods where the implementation can define private types.

Any property or method defined within the class is accessible by preceeding it by 'self'. Quick example:

@interface TestViewController ()
@property NSString *name;
@end

@implementation TestViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.name = @"Terrez";
    NSLog(@"Name : %@",self.name);
}
