What is GeospatialSwift?

GeospatialSwift is an interface to translate a GeoJson document / dictionary into a swift object which fully conforms to the more recent GeoJson specification - August 2016.

A GeoJsonObject can be transformed to a bounding box.

Features

  • Unit tested with high coverage
  • Ongoing development

Installation

Carthage

github "MonsantoCo/GeospatialSwift" ~> 1.0.0

Package Manager

.package(url: "git@github.com:MonsantoCo/GeospatialSwift.git", from: "1.0.0")

Geospatial

Geospatial

  • The main interface consisting of 4 sub interface

GeoJson

Geospatial.geoJson

  • Full GeoJson specification support to create a GeoJsonObject
  • A GeoJsonObject is the base object of GeospatialSwift functionality
  • Bounding Box generated from any GeoJsonObject
  • GeoJson generated from any GeoJsonObject

GeoJsonObjects

  • Minimum distance to a given point (Optional error distance)

  • Contains a given point (Optional error distance)

  • Bounding box for any shape

  • GeoJson returned as a Dictionary

  • Coordinates array for the associated geometry

  • Line segments with midpoint and bearing functions

  • Point

    • Normalize

  • MultiPoint

  • LineString

    • Length

  • MultiLineString

    • Length

  • Polygon

    • Centroid
    • Area

  • MultiPolygon

    • Area

  • GeometryCollection

  • Feature

  • FeatureCollection

Geohash

Geospatial.geohash

  • Create a geohash from a coordinate or bounding box
  • Get geohash neighbors (8)
  • Create a bounding box for a geohash

WKT - Not Fully Supported

Geospatial.parse(wkt: String) -> GeoJsonObject

  • Minimal WKT parsing support which transforms to a GeoJsonObject.
  • POINT, LINESTRING, MULTILINESTRING, POLYGON, MULTPOLYGON.
  • This is currently only intended to parse a very simple WKT string

Running GeospatialSwift in XCode

  • Bootstrap Example: rm -rf *.xcodeproj || rm -rf .build || swift package resolve && swift package generate-xcodeproj && open *.xcodeproj
  • In the Target GeospatialSwift, select the tab Signing & Capabilities and check the box Automatically manage signing
  • In the scheme menu, select Edit Scheme..., select the Test item on the left, select the tab Options, and check the box Gather coverage for "all targets"
  • In the target GeospatialSwiftTests select the tab Build Phases and add a Run Script Phase with the body $PROJECT_DIR/Scripts/parrot.sh and move the item to the top of the Buld Phases just below Dependencies.
  • In the target GeospatialSwift select the tab Build Phases and add a Run Script Phase with the body $PROJECT_DIR/Scripts/swiftlint.sh.

Extending GeospatialSwift in XCode

Option 1: Run with the current XCode project as is

Option 2: Rebuild it using generate-xcodeproj

  • Setup: Package Manager Example: rm -rf *.xcodeproj || rm -rf .build || swift package resolve && swift package generate-xcodeproj && open *.xcodeproj
  • Building: In the Target GeospatialSwift, select the tab Signing & Capabilities and check the box Automatically manage signing
  • Code Coverage: In the scheme menu, select Edit Scheme..., select the Test item on the left, select the tab Options, and check the box Gather coverage for "all targets"
  • Mocking: In the target GeospatialSwiftTests select the tab Build Phases and add a Run Script Phase with the body $PROJECT_DIR/Scripts/parrot.sh and move the item to the top of the Buld Phases just below Dependencies.
  • Linting: In the target GeospatialSwift select the tab Build Phases and add a Run Script Phase with the body $PROJECT_DIR/Scripts/swiftlint.sh.
