A collection of extensions that add async methods to existing Apple APIs. These allow you to replace delegates and callbacks with modern Swift concurrency ā making code easier to reason about. š
Integrate it in your project via the Swift Package Manager. Just add https://github.com/markiv/SwiftAsyncShims.git to your list of dependecies.
Use the convenience CLLocationManager initializer with support for common configuration parameters:
let manager = CLLocationManager(distanceFilter: 100)Ask for permission if necessary, and then get a single location:
if await manager.requestWhenInUseAuthorization().isAuthorizedWhenInUse {
print("Authorized!")
do {
let location = try await manager.requestLocation()
print(location)
} catch {
print(error)
}
}You can also ignore the return value and check authorizationStatus as usual.
await manager.requestWhenInUseAuthorization()
ā®
if manager.authorizationStatus.isAuthorizedWhenInUse {
ā®
}Request an asynchronous stream of locations. Because the stream is an AsyncSequence, the call point can use the for-await-in syntax to process each location instance as produced by the stream ā and a simple break statement to stop the stream. This also allows us to use sequence operators such as prefix, map, reduce and max, for example:
if await manager.requestWhenInUseAuthorization().isAuthorizedWhenInUse {
print("Authorized!")
do {
// Get at most 5 locations in an asynchronous stream
for try await location in manager.requestLocationStream().prefix(5) {
print(location)
if location.horizontalAccuracy < 50 {
print("Stopping the stream...")
break // stop updating locations
}
}
} catch {
print(error)
}
} else {
// Show Settings button
}
