# SwiftTimeZoneLookup
|
|
|
|
[](https://github.com/patrick-zippenfenig/SwiftTimeZoneLookup/actions/workflows/test.yml)
|
|
|
|
Resolve geographical coordinates to timezones and countries. This is a Swift wrapper for [ZoneDetect](https://github.com/BertoldVdb/ZoneDetect)
|
|
|
|
## Usage
|
|
Add `SwiftTimeZoneLookup` as a dependency to your `Package.swift`
|
|
|
|
```swift
|
|
dependencies: [
|
|
.package(url: "https://github.com/patrick-zippenfenig/SwiftTimeZoneLookup.git", from: "1.0.0")
|
|
],
|
|
targets: [
|
|
.target(name: "MyApp", dependencies: [
|
|
.product(name: "SwiftTimeZoneLookup", package: "SwiftTimeZoneLookup"),
|
|
])
|
|
]
|
|
```
|
|
|
|
In your code
|
|
```swift
|
|
import SwiftTimeZoneLookup
|
|
|
|
|
|
let database = try SwiftTimeZoneLookup()
|
|
guard let timezone = database.simple(latitude: 47.5, longitude: 8.6) else {
|
|
fatalError("Timezone not found, coordinates invalid?")
|
|
}
|
|
print(timezone) // "Europe/Zurich"
|
|
|
|
|
|
guard let lookup = database.lookup(latitude: 47.5, longitude: 8.6) else {
|
|
fatalError("Timezone not found, coordinates invalid?")
|
|
}
|
|
print(lookup) // SwiftTimeZoneLookupResult(timezone: "Europe/Zurich", countryName: Optional("Switzerland"), countryAlpha2: Optional("CH"))
|
|
|
|
```
|
|
|
|
## Build database
|
|
SwiftTimeZoneLookup comes with an integrated database. The database can be updated with the following commands:
|
|
|
|
```bash
|
|
git clone --recurse-submodules git@github.com:patrick-zippenfenig/SwiftTimeZoneLookup.git
|
|
|
|
brew install shapelib wget
|
|
cd Submodules/ZoneDetect/database/builder
|
|
|
|
# make sure to select to newest version in make.db script
|
|
|
|
LIBRARY_PATH=/opt/homebrew/Cellar/shapelib/1.5.0/lib CPATH=/opt/homebrew/Cellar/shapelib/1.5.0/include ./makedb.sh
|
|
|
|
cp out_v1/timezone* ../../../../Sources/SwiftTimeZoneLookup/Resources
|
|
|
|
```
