WCSession on Apple Watch not work properly - ios

Question

I have XCode 7, iPhone6 with iOS 9.1, Apple Watch with WatchOS 2.0 (now I update to 2.0.1)
I try to make communication between Watch and iPhone.
On iPhone I init my singleton
- (instancetype)init {
self = [super init];
if (self.isConnectivityAvailable) {
session = [WCSession defaultSession];
session.delegate = self;
[session activateSession];
}
return self;
}
- (BOOL)isConnectivityAvailable {
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"9.0")) {
return [WCSession isSupported];
} else {
return NO;
}
}
in AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//custom code
(void)[AppConnectivityHandler instance]; //start App connectivity with Apple Watch
return YES;
}
And it is all good
I process message like that
- (void)session:(WCSession *)session didReceiveMessage:(NSDictionary<NSString *,id> *)message replyHandler:(void (^)(NSDictionary<NSString *,id> * _Nonnull))replyHandler {
LOG(#"receive message");
NSString *request = message[kRequestKey];
__block NSDictionary *reply = #{};
dispatch_sync(dispatch_get_main_queue(), ^{
if ([request isEqualToString:kRequestDayInfo]) {
//formirate reply dictionary
}
});
LOG(#"send reply");
replyHandler(reply);
}
On my Watch I start load when called function in my main interface controller
- (void)willActivate {
[super willActivate];
if ([WatchConnectivityHandler instance].isConnectivityAvailable) {
[[WatchConnectivityHandler instance] loadDayInfoWithCompletion:^(NSError * _Nullable error, WatchDayInfo * _Nullable dayInfo) {
//code
}];
} else {
//error
}
}
My watch singleton
+ (nonnull instancetype)instance {
static WatchConnectivityHandler *instance;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
instance = [WatchConnectivityHandler new];
});
return instance;
}
- (instancetype)init {
self = [super init];
if (self.isConnectivityAvailable) {
session = [WCSession defaultSession];
session.delegate = self;
[session activateSession];
}
return self;
}
- (BOOL)isConnectivityAvailable {
return [WCSession isSupported];
}
- (void)loadDayInfoWithCompletion:(void(^ _Nonnull)( NSError * _Nullable error, WatchDayInfo * _Nullable dayInfo))completion {
[session sendMessage:#{kRequestKey : kRequestDayInfo} replyHandler:^(NSDictionary<NSString *,id> * _Nonnull replyMessage) {
NSLog(#"reply");
dispatch_sync(dispatch_get_main_queue(), ^{
NSLog(#"%#", replyMessage);
//custom code
completion(nil, /*custom object*/);
});
} errorHandler:^(NSError * _Nonnull error) {
NSLog(#"error");
dispatch_sync(dispatch_get_main_queue(), ^{
NSLog(#"%#", error);
completion(error, nil);
});
}];
}
So it work fine in first time and I get reply. But then I start a lot of errors like
Error Domain=WCErrorDomain Code=7007 "WatchConnectivity session on paired device is not reachable."
Error Domain=WCErrorDomain Code=7014 "Payload could not be delivered."
I test on Watch, and it is often problem to get reply form my iPhone, it wait a long. But on iPhone I test, that when it get message from Watch, it very quick send reply, but I don't see that reply on Watch.
I need update my info every time when watch start my app. What the problem? Maybe I use not properly functions?

Use transeruserinfo method instead of sendmessage and use didreceiveuserinfo method instead of didreceiveapplicationcontext.
