Logging happening in non debug mode as well

[Ankish]

Describe the bug Logging happening in production non debug mode

To reproduce Watch the console for automatic logging happening in sdk

Expected behavior Nothing should be printed

Logs FlagRequestTracker.trackRequest(flagKey:reportedValue:featureFlag:defaultValue:context:) etc

Library version 5.7.0

XCode and Swift version For instance, XCode 15.3, Swift 5.10

Platform the issue occurs on iPhone, iPad, macOS, tvOS, or watchOS.

Additional context Switch off complete logging for safety as well.

[tanderson-ld]

HI @Ankish, it is intended behavior that logging happens even in a release build. If that is not desirable, you can disable logging on the config using the following.

config.logger = .disabled

Does that address the issue or am I misunderstanding?

[EugeneGordin2303]

I also see this issue, and yes I did try to disable it, but still see the logs @tanderson-ld

[tanderson-ld]

@EugeneGordin2303 , thanks for providing additional input. I will be lumping this in with SC-245493 which also relates closely to undesired logs.

[tanderson-ld]

@EugeneGordin2303 , what version are using?

[tanderson-ld]

@Ankish, your original post says the version you are using is 5.7.0. 5.7.0 does not exist. Is that supposed to be 4.7.0?

[EugeneGordin2303]

@EugeneGordin2303 , what version are using?

@tanderson-ld LaunchDarkly (9.7.2)

[tanderson-ld]

@EugeneGordin2303 , are you seeing logs like in the attached when .disabled is provided? Perhaps you are seeing this issue which stems from one of our other packages. I'm also working on fixing that issue.

If you are seeing different logs, what logs are you seeing?

[EugeneGordin2303]

I see lots of logs like these.

[Ankish]

@tanderson-ld : Sorry its 9.7.0

[tanderson-ld]

@Ankish and @EugeneGordin2303, we released 9.8.1 which includes a fix that has the LDEventSource use the same logger as the rest of the iOS SDK. This should resolve issues related to logs such as [LDEventSource] State: raw -> connecting.

I was unable to determine why you are seeing...

FlagRequestTracker.trackRequest(flagKey:reportedValue:featureFlag:defaultValue:context:)
etc

... if you have set the logging to disabled with

config.logger = .disabled

[tanderson-ld]

@Ankish , have you had a chance to try the latest version and if so, do you continue to see the issue after disabling loggin?

We really do not want any logging , if its turned off It kind of violates the security to leak important keys. This is with 9.7.2

[tanderson-ld]

@Ankish, we do not see logs when we use .disabled and other customers in other issues have confirmed that using .disabled turns off logging for them. Can you double check through some other modification that the code with .disabled is being installed? Which platform was the output from your most recent comment?

[EugeneGordin2303]

@tanderson-ld you said 9.8.1 but I see that pod does not have it. I tried to install it using pods but getting this: CocoaPods could not find compatible versions for pod "LaunchDarkly"

When I'm not using version specifier it just installs LaunchDarkly (9.7.2)

[tanderson-ld]

When I run pod search LaunchDarkly

I get:

Multiple third party sites see 9.8.2 including this one

[EugeneGordin2303]

what is the min iOS version supported ?

[EugeneGordin2303]

12, I think, OK...well...no idea lol

[EugeneGordin2303]

got it...good old pod cache duh

[tanderson-ld]

Did it fix the logging issue @EugeneGordin2303 ?

[EugeneGordin2303]

Yes! Great! Thank you

[tanderson-ld]

@Ankish, we are closing this issue since two other customers have confirmed this latest version does disable logging when .disabled is used. Please re-open this if you find the latest version doesn't fix your issue.

[Ankish]

@tanderson-ld : I updated to 9.8.2 I still see logging happens, even if disabled. I even removed complete cache and installed.

[keelerm84]

@Ankish something else must be at work here if you are still seeing logging from our SDK.

Can you please provide the exact logs you are seeing once again?

I would also like to have you try reproducing this problem under a much simpler app. Please apply the below patch to the Hello Example app. You can apply it with patch -p1 < my.patch

Once you have done that, can you confirm if you are seeing any logging in that situation?
