It's based on an object-oriented programming approach, which revolves around dividing code into classes and methods. Objective-C was introduced in the 1980s, and introduced tools that eventually became the Cocoa platform for iOS, macOS, watchOS and tvOS development. Decode a full code: if let coord = OpenLocationCode.So, which to choose: the proven and robust - but possibly outdated - Objective C, or the newer Swift? In this article, we'll look at the history and key features of each language, and review some considerations to take before choosing one over the other. Print( "Open Location Code: \( code10Digit ) ") Encode a location with specific code length.
Import OpenLocationCode // Encode a location with default code length. Versions 1.x of Open Location Code for Swift were designed for Swift 3.2,.
Versions 2.x of Open Location Code for Swift are designed for Swift 4.0. Versions 3.x of Open Location Code for Swift are designed for Swift 5.0. This library is provided as a Swift and Objective-C Cocoa Frameworkįor iOS, macOS, tvOS and watchOS, and as a pure Swift module This allows single-character refinements. Sensible, since an odd-numbered length would have sides in a ratio of 20:1.Īt position 11, the algorithm changes so that each character selects one Reduces the area of the code by a factor of 400. The first 10 characters are pairs ofĬharacters, one for latitude and one for latitude, using base 20. An 11 character code represents approximately A 10 character code represents a 13.5x13.5 To recover the original code, the same location is not required, as long asĬodes represent rectangular areas rather than points, and the longer theĬode, the smaller the area. That in many cases, only four to seven characters of the code are needed. The codes can be generatedĪnd decoded offline, and use a reduced character set that minimises the chanceĬodes are able to be shortened relative to a nearby location. Open Location Codes are short, 10-11 characterĬodes that can be used instead of street addresses. Has Open Location Code support for many other languages. It supports Swift and Objective-C projects on iOS, macOS, tvOS and This repository is the Swift implementation of Open Location Code. ShortenĪnd recover Open Location Codes for a given reference location. Open Location Code for Swift and Objective-CĬonvert between decimal degree coordinates and Open Location Codes.
