iOS8, Swift, Node.js, MQTT, NOSQL. This session will bring the developer on a journey that bridges the gap between the mobile device and the cloud using cutting edge technologies to build engaging applications focused on the "Lean Startup" mentality where developers can experiment with a variety of technologies and garner rapid feedback from their stakeholders. Using an open cloud environment and Apple’s introduction of the Swift Programming language, we can demonstrate how application development can be in the cloud and leverage core technologies such as NoSQL Data and Interactive Push Notifications to create compelling and engaging applications via MQTT while leveraging high scalable cloud infrastructure for hosting cloud based scripting technologies based upon Node.js.

2. The new normal of IT focus
and investment…
Three methods of new value creation:
Alone, each of these has immense potential.
Integrated, they change everything.
Drive people-centric
Engagement
for new profit
channels
Utilize Data
as the new basis
of competitive
advantage
Leverage Cloud
as growth engine
for business

3. Building “engaging” apps is hard
• Time to market requirements must be quicker… weeks not
months
• More experimental in nature… LEAN approaches to testing the
market are needed.
• Mobile brings its own set of challenges… from device
fragmentation to scale to surges of demand to connecting
securely into enterprise data
• Greater data capture requirements… on all apps to drive
analytics
• Developers of engaging apps want to use multiple languages
and Cloud APIs…

4. The IBM MobileFirst Platform contains the
ingredients for a successful mobile program
Available on premises or in the cloud.
Efficiently
Develop &
Integrate
Easily
Secure
Personalize
Engagements
Continuously
Deliver

5. The three essential ingredients to
building apps for the “new normal”
A platform to secure your
apps, manage their
lifecycle, and integrate
them into the enterprise
Cloud APIs that can be
glued together to quickly
create new apps at scale
Synchronized data across
devices that can scale to
meet mobile demand

/**
* Executed when the Google+ authentication flow returns control to the application.
*/
- (void)finishedWithAuth: (GTMOAuth2Authentication *)auth error: (NSError *) error {
if(!error){
[self queryGooglePlusUser];
}
}
/**
* Fetch the authenticated user's Google+ information.
*/
-(void) queryGooglePlusUser
{
GTLServicePlus* plusService = [[GTLServicePlus alloc] init];
plusService.retryEnabled = YES;
[plusService setAuthorizer:[GPPSignIn sharedInstance].authentication];
GTLQueryPlus *query = [GTLQueryPlus queryForPeopleGetWithUserId:@"me"];
[plusService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,
GTLPlusPerson *person, NSError *error) {
if (error) {
GTMLoggerError(@"Error: %@", error);
} else {
[self buildCustomer:(person)];
}
}];
}

15. Cloudant NoSQL Database
• Fully managed Cloudant NoSQL database provides data layer that is
transparent and always on
• Client-side APIs provide intuitive environment for storing data on the cloud
• CRUD support, online and offline replication with only a few lines of code
• Map simple objects to JSON documents using default or custom object mapper
• Object Models - Items, Shopping Cart, Stores, and Purchase History
Shopping Cart
/*!
* Handles the logic for adding an item to the cart.
*/
-(void) addToCart:(Item *)itemToAdd withColor:(ColorObject*)color andSize:(NSString*)size
andItemURL:(NSString*)url
{
self.totalItems++;
NSString *itemKey = [self generateKey:itemToAdd withColor:color.colorName andSize:size];
self.total = [self.total decimalNumberByAdding:itemToAdd.price]];
if ([self.itemsInCart keyExists:itemKey]) {
CartItem *cartItem = (CartItem*)[self.itemsInCart objectForKey:itemKey];
cartItem.quantity++;
return;
}

pushService.environment = @"sandbox";
[pushService registerDeviceToken:deviceToken completionHandler:
^(IMFResponse *response, NSError *error) {
if (nil != error){
NSLog(@"Error register device token with error: %@", error);
} else {
NSLog(@"Device has been registered with response: %@", response);
[pushService subscribeToTags:tag completionHandler:
^(IMFResponse *response, NSError *error) {
NSLog(@"Subscribed to tag with response: %@", response);
}];
}
}];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:
(NSDictionary *)userInfo
{
NSString *message = [[[userInfo valueForKey:@"aps"]
valueForKey:@"alert"] valueForKey:@"body"];
[UIApplication sharedApplication].applicationIconBadgeNumber =
[[[userInfo objectForKey:@"aps"] objectForKey:@"badgecount"] intValue];
[self showNotification:message];
if ([[[userInfo valueForKey:@"aps"] valueForKey:@"category"]
isEqualToString:@"PURCHASE_CHANGE"]){
if (application.applicationState == UIApplicationStateActive){
[[self notificationCenter] postNotificationName:@"Purchase_Change"
object:nil userInfo:userInfo];
[[PushService pushInstance] resetPushCounter];
} else if (application.applicationState == UIApplicationStateBackground
|| application.applicationState == UIApplicationStateInactive){
[[self notificationCenter] postNotificationName:@"Purchase_Change"
