discoverAllContactUserInfosWithCompletionHandler results blank - ios

Having trouble with CloudKit's discoverAllContactUserInfosWithCompletionHandler not returning anything in the discoveredUserInfo array. I have a test app on two phones. One person can see the other (discoverAllContactUserInfosWithCompletionHandler returns the 2nd user's info via lookup) but not vice-versa. I checked all the settings on both phones, including iCloud Drive->Look Me Up By Email, the correct email addresses in the contacts list, iCloud drive is turned on for the app. Everything.
I noticed that even on the phone that can see the 2nd user, sometimes the discoveredUserInfo array is blank and sometimes it returns the 2nd user, seemingly at random.
Anyone else seeing this kind of behaviour?

It looks like Apple only allows e certain amount of requests per period. You would then expect a CKError. I created a bug report with apple for this (ID = 19712839)
I would suggest that you do the same.

iPhone contact details corrupted how can I fix them?

At some point I noticed I’m seeing vcard coding or something to that effect and a bunch of my iPhone contacts. Please look at the example is there any way to fix this without having to go into each individual contact and delete the tags etc. it looks to be some type of V card code reference.
As you can see in the attached image for Apple headquarters, there is corrupted data. This is happening in a lot of my contacts I am seeing things such as X-SOCIALPROFILE at the end of phone numbers, etc..
I have another client that is experiencing the same issue (both with phone number and country name fields). I am posting something to the Apple forum hoping that someone there has an answer.
I think I figured out the issue.
Adding my work email, I had accidentally checked sync contacts. It is Microsoft based so it corrupted a bunch of my contacts trying to pull vCard data etc.
Also, Facebook messenger was corrupting my contacts
I disabled both of these syncing features, on my Mac went into contacts and searched for “x”
I found a lot of things like X-social etc appended to phone numbers etc
Based on this search in contacts I has to manually cleanup about 30 contacts. After about 1 hour my phone was synced to the updated iCloud contacts and everything is good.
Bottom line. Choose one source of truth to sync your contacts like iCloud.
Don’t allow 3rd party apps to access your contacts.
If you need anymore information let me know

CloudKit: can't discover identities

Pretty new to CloudKit. Trying to get all the contacts who are using my app. According to the docs and the tutorials out there I'm calling this:
discoverAllIdentities(completionHandler:)
The issue is that only my user (the one who is logged in on the device where the app is running) is returned. So I did some digging and noticed that if I call this one:
discoverUserIdentity(withPhoneNumber:completionHandler:)
and I use phone number directly the user is returned.
So after more investigation, I figured that the reason I do not get those users is that in my Contacts those users do not have their iCloud email stored. So once I add the email, they are returned by discoverAllIdentities(completionHandler:). So it appears the default implementation of that method is tied to iCloud emails for the discovery instead of phone number.
Is it possible to use phone number for discoverAllIdentities(completionHandler:)? Since, I don't think that as you add a new contact you would record anything but just phone number, so you will be missing to discover all those users.
Any kind of help is highly appreciated.

Tracking User with Google Ad Link

I'm not sure I've stated the title correctly, but I have what I think is an unusual issue. Not something I'm terribly worried about but curious. If I'm tagging this inappropriately I apologize.
I have a google ad running and track clicks using Final URL. So I track keywords, Ad_ID, Location, etc. Looking at the database I noticed that I am getting a hit on my website from what appears to be one user fairly regularly (sometimes minutes apart - other times days - 3200 entries) for the last 2 years, at least to when I started tracking this way. The entry shows the same keywords and the same location - which is local - a mobile device - but not an Ad_ID or a referring URL. I take the google info from the query string in the url so the query string would have to be the same every time.
I recently added a tracking cookie (long expiration) on the user end and this activity shows up with a different cookie value every time meaning either its either a different device or the device doesn't accept cookies. Each hit also starts a new session.
These hits do not show up as clicks on Google Ads so I'm not being charged, it also means that someone is not actually out there clicking on the ad.
I don't see where this is causing problems but am curious as to where this may be coming from. I don't know if there is a way to stop it.
So nothing critical but ideas on what might be causing this would be appreciated. I also get a ton of spam or bot hits on the site but that's a different issue.
Thanks!

CloudKit share participant no longer returns name

I'm working on an app that uses CloudKit sharing functionality. The sharing features have been working great, but recently I no longer get the user names back from the CKShare.Participant when a user accepts the sharing request.
Details
I'm using the built-in UICloudSharingController to set up the share, which works and sets up the share properly.
When the invited user accepts the share, the owner gets a notification of the change in the zone and then fetches the CKShare.
The fetched CKShare object has an array of share participants (CKShare.Participant), which has a nameComponents property. I've used this in order to get the first and last name of the participants to display in the UI. This was all working fine until recently.
Now, however, I'm only getting values in nameComponents for the owner of the share. The accepted participants have nil values for the nameComponents.givenName and nameComponents.familyName.
I have not changed anything in this part of my code in some time, so don't think I've caused this. I've tried this on iOS 11, 11.4, 12, 12.1 and all have the issue. This leads me to believe there might have been a change on the server side from Apple.
Note
I am not requesting .userDiscoverability permissions. I have not had to do that in order to get the names once a user accepts. I realize that I can request that and then use CKDiscoverUserIdentitiesOperation to get the names. But I'd rather not as I don't want the dialog, which is confusing for users.
Has anyone seen this change? Or better, yet, does anyone have any suggestions for tracking down the cause or fixing it?
Thanks.

How to implement an iOS app personalized start page?

I'm developing my first iOS app and I'm facing a challenge.
I'd like to present new users a personalized screen when the app starts at the first time. Let me explain more.
The flow should be more or less like this:
My app isn't installed on the user's device.
Then the user gets an SMS on his iPhone with a short message and a link to install my app. The message is part of a conversation. Another user of this app had sent this message (through my backend) in order to join this user to the conversation.
This install URL doesn't necesarrily link directly to the itunes store, it can link to a conversations specific link such as myapp.com/conv/12345
The page at myapp.com/conv/* will detect the device and if it's an iPhone would redirect the user to the appstore to install myapp.
The user then installs myapp and launches it.
Now I'd like to present the same conversation 12345 to the user, before he even needs to login, register or what have you. That's the difficult part... I don't want the user to start an a blank page, I'd like to take it right to the conversation 12345 page.
I assume steps 1-5 are easy, but I can't think of a way to implement 6. I admit that I'm not familiar enough with the intrinsic of the appstore but as far as my understanding goes, "all apps are made equal", I mean the app itself when it gets installed it has no context, it doesn't know what "caused" it to be installed, it isn't aware of the click on myapp.com/conv/12345. Is this correct?
If there was a way for an app to know something like a referrer URL for the instllation or something along these lines that would be awesome.
If there was a way for app to query the device for its phone number
then I could make this work (b/c the SMS was sent to a specific phone
number, so I can track the most recent conversation sent to this
number on my backend). But since apps are sandboxed, accessing the phone
number is off limit.
Well, I suppose I could ask the user to type a unique code from the SMS when the
app starts, say 12345 and then I'd be able to display the
conversation to him. But that's problematic in two ways, first,
security - the user can join a conversation not meant
for him, and second, that's less than optimal
user experience, I want this to work like magic, I don't want to make
users memorize and type strings into my app the first time they
install, I'm sure they won't appreciate it... (they could
copy-paste, but still...)
Another option is asking the user to type his phone number. But that
again has a few drawbacks, one is that again it's less than optimal
UX, I'm asking a user to type his phone number to an app he doesn't
yet know or trust, second I'll need to verify (authenticate) the
phone number, I mean what prevents that user from typing a phone
number that doesn't belong to him?
If I had access to the SMSs then I could dig up that code, but I find
it hard to believe that apps get access to SMSs, it's just sounds
like another reasonable sandbox restriction. Of course I'm not
speaking of jailbroken devices.
BTW, if the user just went over to the appstore to install my app (and didn't go through a conversation SMS) that's fine, in this case I'll just present a normal register/login page. The interesting case is where the user was already part of the conversation when receiving the SMS and now I want him to (effortlessly) become part of the same conversation through my app.
To sum up - is there a trick to present "personalized" pages the first time an app is installed and launched that would get that user right into the context of the conversation sent to him over SMS without having to request additional input?
Thanks!
It's impossible to do. Your application is installed without the knowledge you need whatsoever. As you pointed out, it's a reasonable sandboxing restriction.
What you could do is a challenge-response based system, but it would be about as intrusive to the user as is registering/login in.
Ran, you can keep a flag in NSUserDefaults (equivalent to Android's SharedPreferences)
