GeoPackage iOS Documentation

Welcome to the GeoPackage iOS Documentation! This guide aims to provide you with detailed information on how to use the GeoPackage library in iOS development. GeoPackage is an open, standards-based, platform-independent, and self-describing data container format for storing geospatial information.

Getting Started

Step 1: Install GeoPackage iOS

To get started, you need to install the GeoPackage iOS library. Follow these steps:

  1. Open your Xcode project.
  2. Go to the “File” menu and select “Swift Packages” -> “Add Package Dependency”.
  3. Enter the following repository URL: https://github.com/ngageoint/geopackage-ios.git
  4. Choose the latest version or a specific release that suits your needs.
  5. Click “Next” and follow the Xcode prompts to add the package to your project.

Step 2: Import GeoPackage

To use the GeoPackage features in your project, you need to import the GeoPackage module:

“`swift
import geopackage
“`

Usage

Basic Operations

Create a GeoPackage

To create a new GeoPackage file, use the following code:

“`swift
let gpkgPath = // Provide desired file path
let gpkg = try? GeoPackage.create(gpkgPath)
“`

Open an Existing GeoPackage

To open an existing GeoPackage file, use the following code:

“`swift
let gpkgPath = // Provide path to existing GeoPackage file
let gpkg = try? GeoPackage.open(gpkgPath)
“`

Working with Tables

Create a New Table

To create a new table in a GeoPackage, use the following code:

“`swift
let tableName = // Provide desired table name
let tableDefinition = // Provide table definition
let table = try? gpkg.createTable(tableName, tableDefinition)
“`

Querying and Modifying Data

Execute a Query

To execute a SQL query on a GeoPackage table, use the following code:

“`swift
let query = // Provide SQL query
let results = try? table.query(query)
“`

Inserting Data

To insert a new row into a GeoPackage table, use the following code:

“`swift
let values = // Provide data values for the new row
try? table.insert(values)
“`
