Crashes due to No such table exists Exception
Goals
After updating the Realm version from 10.7.5 to 10.10.0 Crashlytics is reporting us following problems:

Unfortunately I can not provide steps to reproduce as I am not able to receive this crash. We know from the users that this crash occurs at the realm first initialisation. There where no changes in database structure between update from 10.7.5 to 10.10.0.

Here's some code that will hopefully be helpful:
class AssetCacheDSO: Object {
@Persisted(primaryKey: true) var name = ""
@Persisted var assetIDs = List<String>()
}
private func getAssetIDs(in cache: AssetCache) -> [String] {
guard let cacheObject = getCache(cache) else {
return []
}
let assetIDs = cacheObject.assetIDs
for assetID in assetIDs { // it always fails when trying to enumerate the assetIDs
print(assetID)
}
return Array(assetIDs)
}
private func getCache(_ cache: AssetCache) -> AssetCacheDSO? {
let caches = realm.objects(AssetCacheDSO.self)
return caches.first(where: { $0.name == cache.cacheName })
}
@gbreen12 can we see how MobileHelpersDataAssetStorage works and how it interacts with your SwiftUI views?
@Kysiek @gbreen12 are you using realms on multiple threads and are you observing any realms / realm objects anywhere?
@Kysiek @gbreen12 are you using realms on multiple threads and are you observing any realms / realm objects anywhere?
@leemaguire In my project I use instances of Realm on different threads, but on every thread I am instantiating the instance with empty initialiser. And yes, in my project I see code which is observing realm objects. Do you think it may be a cause for these crashes?
@Kysiek is there any chance that you are deleting the object on a different thread when it is being read on another?
but on every thread I am instantiating the instance with empty initialiser
Can you show code explaining this?
Thanks
So I can reproduce consistently but only on a client's device (iPhone 12). It works on my device just fine (iPhone Xr). Here's my AssetStorage:

let assets = all().filter("id IN %@", assetIDs)
return Array(assets.map { AssetDTO($0) })
}
public func getCachedAssets(inAll caches: [AssetCache]) -> [AssetDTO] {
guard !caches.isEmpty else {
return []
}
var assetIDs = getAssetIDs(in: caches.first!)
for i in 1..<caches.count {
if assetIDs.isEmpty {
return []
}
assetIDs = assetIDs.filter { getAssetIDs(in: caches[i]).contains($0) }
}
return loadAll(filteredBy: NSPredicate(format: "id IN %@", assetIDs))
}
public func getCachedAssets(in cache: AssetCache) -> [AssetDTO] {
guard let assetCache = getCache(cache) else {
return []
}
let assetIDs = assetCache.assetIDs.split(separator: ",").compactMap { String($0) }
return loadAll(filteredBy: NSPredicate(format: "id IN %@", assetIDs))
}
public func addCache(in cache: AssetCache, containing ids: [UUID]) {
let assetCache = AssetCacheDSO()
assetCache.name = cache.cacheName
assetCache.assetIDs = (ids.map{$0.uuidString}).joined(separator: ",")
try! realm.write {
realm.add(assetCache)

I'm not watching anything and I don't think it's having any threading issues because I basically immediately change my DSO (realm object) to a DTO as soon as it comes out of the storage class.
@gbreen12 are you able to get the clients realm file and use it from your device to see if the crash can be reproduced locally?
@gbreen12 do you have access to their phone? If so you could grab it by doing what's described here https://developer.apple.com/forums/thread/21660
Can you show me how you do the DSO DTO conversion? observeAll. Is RealmStorage used across multiple threads?
You know what, I lied. This particular case doesn't use a DTO. I just get that cache DSO and then attempt to get the string list.
Unfortunately I can't get the realm file because it's in a shared folder and I've already updated the code to use a comma separated string over a list of strings and he has updated the app.
Ok, just for further reference know that accessing a object after you have deleted it should hit NoSuchTable. Although we have checks in place to prevent this, if you time it really specifically from a multi thread / process scenario there is a chance you can bypass the checks in the Cocoa layer and hit this exception in our Core layer.
This happened again on another app on another device. Here is the full stack trace:

Part of the problem is this code and database are shared among multiple apps. The "work around" is to have the user delete all our apps and reinstall and resync from the server. Then it fixes it even when using the same app version.
This always seems to be an issue when trying to get a list of strings, Realm thinks I'm trying to access a foreign table. It's happened on multiple entities over the time I've seen it.
Yeah the database is being shared in an app group.
Any news on this issue?
I've also noticed this in production, but never managed to reproduce it myself.
Realm version: 10.25.0 (I will try to upgrade to 10.29.0 and check if this error will still appear)

I don't know why you can't just create that table. At least you should tell us which table in the error messages.
This is just my guess. Maybe it's the List field in the table causing this issues.
Like the code snippet from @gbreen12 , there are two List in my table.
@objc dynamic var id = 0
@objc dynamic var controller: String = ""
let mainButtons = List<Int>()
let subButtons = List<Int>()
@objc dynamic var createdDate: NSDate = NSDate()
@objc dynamic var lastUpdateDate: NSDate = NSDate()
And there are bunch of fastEnumerator in the error messages, don't know if it's related.
Me again.
I changed to use comma separated String to store List<Int> and the problem solved.
No more no such table errors.
So I think the problem is very easy, just don't search for any table when they are String, Int or something.
The workaround for developers are not to use them.
Do it as the old school String type.
