I am starting to work with Realm on iOS 8 or greater and looking at the documentation in Realm. I noticed that all of the properties have the dynamic keyword in front of them. Is that required in Realm? I have read the Apple documentation on the keyword which can be found here. https://developer.apple.com/library/ios/documentation/Swift/Conceptual/BuildingCocoaApps/AdoptingCocoaDesignPatterns.html

DynamicRealm is a dynamic variant of Realm . This means that all access to data and/or queries are done using string based class names instead of class type references. This is useful during migrations or when working with string-based data like CSV or XML files.
Realm Swift is an easy to use alternative to SQLite and Core Data that makes persisting, querying, and syncing data as simple as working directly with native Swift objects. Deploy a sample appView documentation.
Yes, it is mandatory for normal var properties. From the realm docs.
Realm model properties need the
dynamic varattribute in order for these properties to become accessors for the underlying database data.There are two exceptions to this:
ListandRealmOptionalproperties cannot be declared as dynamic because generic properties cannot be represented in the Objective-C runtime, which is used for dynamic dispatch of dynamic properties, and should always be declared withlet.
The dynamic keyword is what allows for Realm to be notified of changes to model variables, and consequently reflect them to the database.

In Swift 3, we declared our property like this
dynamic var Name : String = "" In Swift 4, we declared our property like this
@objc dynamic var Name : String = "" If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
