• Click on your Main.storyboard and use the interface builder to drag UI elements onto your iOS screen

• Create layouts in XML or w/ the GUI
• You should put your strings in values/strings.xml

• Contains the data your application interacts with
• Usually an Objective-C class w/ properties & methods 
• .h is a header file and .m is an implementation file for method implementations and to synthesize any properties (if needed)

@interface CulpaProfessor : NSObject
// declare properties of the class (variables you can access with each // object) here@property NSString *firstName;
// declare the public methods here-(BOOL) checkProfessorMatch:(NSString *)matchQuery;@end

• Basically a Java class that holds the properties for your data and contains helper methods to manipulate or give information about that data

• ctrl-drag from buttons (or other UI elements) to your ViewController class to create an action method
• ctrl-drag UI elements to your ViewController interface file to create a UI outlet that you can change

• Rather than control-click drag as in iOS, you will use setOnClickListener();
• Rather than control-click drag to create an IBOutlet, you will use findViewById() to get access to change a UI element

  NSString *requestString = @"https://s3.amazonaws.com/culpa/professors.json";
    NSURL *url = [NSURL URLWithString:requestString];
    NSURLRequest *req = [NSURLRequest requestWithURL:url];
    NSURLSessionConfiguration *config =
    [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:config
                                             delegate:nil
                                        delegateQueue:nil];
    NSURLSessionDataTask *dataTask =
    [session dataTaskWithRequest:req
                    completionHandler:
     ^(NSData *data, NSURLResponse *response, NSError *error) {
           // do stuff with data
     }];
    [dataTask resume];
