SDK Ready Not Firing

[ay8s]

I'm seeing some oddness with the latest update to the SDK where the SDk ready event never gets fired. Initially I thought it may have been down to blocking on my network but also seeing the same issue occur on a device over cellular.

Downgrading to the previous version, the event fires correctly. I saw there was a tweak to loading from cache but would still expect the ready event to fire?

Curious if anyone else has seen similar behavior?

Hi @ay8s Can you please enable SDK debug logging and share with us the logs for both instances so we can investigate?

hi @ay8s Currently, we have an issue related to the latest version of the SDK, you can revert to the previous version to avoid the issue. A new version with the fix is coming soon.

Hi @ay8s Our SDK version 2.24.6 has been released which has the fix for the SDK ready issue.

Thanks @hbqdev. I did try 2.24.6 but seemed to run into the same issue. Only when reverting to 2.24.4 do I see the expected behavior with my Split checks.

Aside from those debug logs. Only the SplitEventSdkReadyFromCache event block gets fired.

Hi @ay8s

it Looks like you are holding the local reference of the SDK.

// LOCAL REFERENCE
func test() {
        let sdkKey = "YOUR_SDK_KEY"
        let defaultKey = "test"
        let key: Key = Key(matchingKey: defaultKey)
        let config = SplitClientConfig()

        let factory = DefaultSplitFactoryBuilder()
            .setApiKey(sdkKey)
            .setKey(key)
            .setConfig(config)
            .build()!

        factory.client.on(event: .sdkReadyFromCache) {
            print("READY CACHE")
        }

        factory.client.on(event: .sdkReady) {
            print("READY")
        }
    }

Can you using a global reference for the SDK and see if that fixes the issue? It would be something like this:

// MODULE REFERENCE 
var factory: SplitFactory!
func test() {

        let sdkKey = "YOUR_SDK_KEY"
        let defaultKey = "test"
        let key: Key = Key(matchingKey: defaultKey)
        let config = SplitClientConfig()

        factory = DefaultSplitFactoryBuilder()
            .setApiKey(sdkKey)
            .setKey(key)
            .setConfig(config)
            .build()!

        factory.client.on(event: .sdkReadyFromCache) {
            print("READY CACHE")
        }

        factory.client.on(event: .sdkReady) {
            print("READY")
        }
}

@hbqdev We're still using Objective-C to setup Split and have the SplitClient available via a Singleton.

Split 2.24.4 still continues to work smoothly.

[SajjadKharrazi]

We are using also v2.24.5

class SplitHelper {

    var isSDKReady = false
    var client: SplitClient!

    func build() {
        let config = SplitClientConfig()
        config.logLevel = .verbose
        let builder = DefaultSplitFactoryBuilder()
        let factory = builder.setApiKey(Environment.SPLIT_API_KEY.value)
            .setKey(Key(matchingKey: UIDevice.current.identifierForVendor!.uuidString))
            .setConfig(config)
            .build()

        self.client = factory!.client
        self.client.on(event: SplitEvent.sdkReady) {
            self.isSDKReady = true
        }
        self.client.on(event: SplitEvent.sdkReadyFromCache) {
            self.isSDKReady = true
        }
    }
}

SDk ready event never gets fired

hi @ay8s @SajjadKharrazi

ios SDK 2.24.7 has been released that addressed this issue.

[ay8s]

Seems to be working smoothly now @hbqdev
