🐛 Bug Report: Swift listCollections crash

[Jaycyn]

👟 Reproduction steps

When I attempt to output a list of collections for an existing database, the Swift SDK crashes.

func listCollections() async throws {
    do {
        let collectionList = try await self.databases.listCollections( //crashes here
            databaseId: databaseId //databaseId is valid. Works with let database = try await databases.get(...
        )
        
        collectionList.collections.forEach { collection in
            print(collection)
        }
    } catch {
        print(error)
    }
}

.listCollections crashes to this code located within Sources>AppwriteModel>Collection.swift

public static func from(map: [String: Any] ) -> Collection {
        return Collection(
            id: map["$id"] as! String,
            createdAt: map["$createdAt"] as! String,
            updatedAt: map["$updatedAt"] as! String,
            permissions: map["$permissions"] as! [String],
            databaseId: map["databaseId"] as! String,
            name: map["name"] as! String,
            enabled: map["enabled"] as! Bool,
            documentSecurity: map["documentSecurity"] as! Bool,
            attributes: map["attributes"] as! [AnyCodable],   // CRASHES ON THIS LINE
            indexes: (map["indexes"] as! [[String: Any]]).map { Index.from(map: $0) }
        )
    }

error thrown

Could not cast value of type '__NSDictionaryI' (0x14201ac90) to 'JSONCodable.AnyCodable' (0x107cca460).

This is what is being returned from the server. Perhaps the [3] = "default" : (no summary) may have something to do with it? A default value is optional

👍 Expected behavior

It should output the list of collections without crashing.

👎 Actual Behavior

It crashes when .listCollections is called

@Jaycyn thanks for raising this issue! looks like the crash is because of default being empty like you suggested, and simply mapping attributes to AnyCodable won't work in this case.

We have noted this issue down and will soon release a fix. Thanks for your patience 🙏

[ChiragAgg5k]

@Jaycyn we just released a new version which should handle this. Apologies for the delay on this 🙏

Let me know your thoughts and if this was able to fix your use case.

Hmm. I removed sdk-for-swift 9.0 completely and added sdk-for-swift 10.1.0 (Via SPM) and have a whole host of fresh errors that didn't exist in the 9 version. Not compile time errors but actual missing functions so it won't compile.

For example upon initializing a client, this code worked previously

self.client = Client()
            .setEndpoint(apiEndpoint)
            .setProject(projectId)
            .setKey(secretApiKey)

however, we now get an error that Client has no member .setKey

Previously, this code worked

let databases = Databases(self.client)
let databaseList = try await databases.list(
    //            queries: [], //optional
    //            search: "<SEARCH>" //optional
)

but now, databases has no .list function

along those same lines, databases.listCollections worked but crashed. Now, .listCollections has gone missing

let collectionList = try await self.databases.listCollections(
    databaseId: databaseId
)
collectionList.collections.forEach { collection in
    print(collection)
}

There are quite a number of other functions that are now missing compared to v9, getCollection, createCollection and createStringAttribute.

Oh, and AttributeEnum is not in the SPM Package files either.

Upon reviewing the sdk-for-swift-10.1.0 download, we can see those functions but when adding the dependency to the project they don't appear to be there.

Perhaps we are doing something wrong?

[ChiragAgg5k]

@Jaycyn functions like setKey, listCollections etc. are server side only functions, and if you are only seeing them not showing up, I am guessing there was somehow a mismatch between sdk-for-apple and sdk-for-swift

can you please verify if the correct package is installed?

Also the issue with package resolution between the sdks still exists. so for now we would recommend you to just have one of those installed at a time in a project

[ChiragAgg5k]

@Jaycyn just did a simple test and it seems to work now:

I think we are good now and we also have it working.

This is a new clean project with the sdk-for-swift only. Not sure where the issue was but upon totally deleting the project and re-creating, adding the SPM sdk-for-swift 10.1.0 it's working.

Thank you again for your help - closing this report.

awesome to hear this!
