In Xcode you are able to create handy little code snippets and call them up via keywords. Below are ones I am using most frequently.

All you have to do is copy the code into Xcode and drag into you Show the Code Snippet library (it’s the curly bracket {} icon) in the Utilities area (right side of Xcode).

Log Object (log)

NSLog(@"%@", <#object#>);

Shared Instance (singleton)

+ (instancetype)sharedInstance
{
    static dispatch_once_t once;
    static id sharedInstance;
    dispatch_once(&once, ^{
        sharedInstance = [[self alloc] init];
    });
    return sharedInstance;
}
