2. Restaurant finder app
in Shibuya

3. 10 things you should
know about watchkit
before you submit
See this one as well

4. There are limitations
on WKInterfaceMap
at this time

5. Current limitations
• Request location access on iPhone, not Apple Watch
• Not scrollable on map
• Not zoomable on map
• Not opening Apple's map app
• 5 annotations at maximum

6. Location service
var locationManager = CLLocationManager()
override init() {
super.init()
locationManager.delegate = self
if CLLocationManager.locationServicesEnabled() {
switch CLLocationManager.authorizationStatus() {
case .AuthorizedAlways, .AuthorizedWhenInUse:
locationManager.startUpdatingLocation()
}
}
}
func locationManager(manager: CLLocationManager!, didUpdateToLocation newLocation: CLLocation!,
fromLocation oldLocation: CLLocation!) {
}

7. Use Handoff in case it's not granted yet
override init() {
let type = "com.example.com"
let userInfo = ["actionID": 1]
self.updateUserActivity(type, userInfo: userInfo, webpageURL: nil)
}

8. Annotation
No annotation for current location
Use custom image instead

9. Cache
Cache annotation images
let image = UIImage()
let device = WKInterfaceDevice.currentDevice()
device.addCachedImage(image, name: "annotation")
self.mapView.addAnnotation(CLLocationCoordinate2DMake(0.0, 0.0)
withImageNamed:"annotation"
centerOffset:CGPointZero)

10. Realm
Realm is a replacement for SQLite & Core Data. It can save you
thousands of lines of code & weeks of work, and lets you craft
amazing new user experiences.

11. Why Realm?

12. Usage between iOS and WatchKit
// Get the shared directory for the application group
let id = "group.com.example.my-app"
let fileManager = NSFileManager.defaultManager()
let container = fileManager.containerURLForSecurityApplicationGroupIdentifier(id)
// Set the default realm path to a location in the shared container
let fileName = "defualt.realm"
if let realmURL = container?.URLByAppendingPathComponent(fileName) {
RLMRealm.setDefaultRealmPath(realmURL.path)
}
// Get location info
let restaurant = Restaurant.allObjects().firstObject() as! Restaurant
let coordinate = CLLocationCoordinate2DMake(restaurant.latitude, restaurant.longitude)

13. App review
We found that the usefulness of your Apple Watch app is limited
by the minimal features it includes. Specifically, your Apple Watch
app only launches out to Maps.
— From Apple

14. There are tons of
functions, but make it
simple

16. PagingMenuItem SegmentedControl

17. Usage
let viewController = UIViewController()
viewController.title = "Menu title"
let viewControllers = [viewController]
let options = PagingMenuOptions()
options.menuHeight = 50
let pagingMenuController = self.childViewControllers.first as! PagingMenuController
pagingMenuController.setup(viewControllers: viewControllers, options: options)
