You can add your own operator overloading of different number types to mitigate the casting required see: https://github.com/jquave/EasyCast You can also add your own String extension for length and index character at in a String with: extension String { var length: Int { return countElements(self) } subscript (i: Int) -> String { return String(Array(self)[i]) } } Which will now let you use `.length` on strings, e.g: "Cat".length; //3 And get the character at index with: "Cat"[1]; //a I've more useful extensions at: https://github.com/mythz/swift-linq-examples/blob/master/src... Which enables LINQ-like querying in Swift: https://github.com/mythz/swift-linq-examples

The main thing I miss from Swift is its extensibility letting you extend primitive types like Arrays or Strings, this lets you easily add LINQ-like capabilities even tho Swift doesn't ship with many, see: https://github.com/mythz/swift-linq-examples Dart comes with a rich functional and Stream API's on collections so most of the time you wont need to extend it (same LINQ examples in Dart: https://github.com/dartist/101LinqSamples), but unfortunately you can't extend built-in (or external) types which means you need to use top-level methods which can break-up the flow of your beautiful expression flows. Extensions is also important for minimizing unnecessary abstraction and maximizing re-usability since you can extend without being forced to create foreign wrapper API's. IMO Extensions are one of the most important traits for keeping a min
