Optional default values?

[martinwennerberg]

Hi,

Is there a way to find out if there's an evaluation for a flagKey?

My problem is that I don't have a defaultValue to pass in to EppoClient at the point where Eppo is integrated in my app.

If for instance instance

func getBooleanAssignment(
    ...
    defaultValue: Bool) -> Bool

looked like this instead:

func getBooleanAssignment(
     ...
    defaultValue: Bool? = nil) -> Bool?

Alternatively there could be a way to find out if the Configuration includes the flagKey.

Or is there another way to get around this?

Hi @martinwennerberg

Have you tried let details = eppoClient.getBooleanAssignmentDetails(...)?

It'll return a details.evaluationDetails.flagEvaluationCode which can take on any of these enum cases

eppo-ios-sdk/Sources/eppo/EppoClient.swift

Lines 459 to 468 in 63fa8aa

	public enum FlagEvaluationCode: String {
	case match = "MATCH"
	case flagUnrecognizedOrDisabled = "FLAG_UNRECOGNIZED_OR_DISABLED"
	case typeMismatch = "TYPE_MISMATCH"
	case assignmentError = "ASSIGNMENT_ERROR"
	case defaultAllocationNull = "DEFAULT_ALLOCATION_NULL"
	case noActionsSuppliedForBandit = "NO_ACTIONS_SUPPLIED_FOR_BANDIT"
	case banditError = "BANDIT_ERROR"
	case unknown = "UNKNOWN"
	}

If a flag doesn't exist or is disabled, the code should be .flagUnrecognizedOrDisabled
