Crash when getting DynamicConfig value

[bodnar-dan]

Description

• We're facing a crash that comes from Statsig library. There's not much manipulation done from our side and I am unable to reproduce, but I do see it in the crash reports.
• It's an early crash, that happens soon after app start (2-5 seconds after the app started, possible while Statsig is updating values);

Staktrace

DynamicConfig.getValue<A>(forKey:defaultValue:)

Crashed: com.apple.main-thread
0  [APP]  0x15cdb1c DynamicConfig.getValue<A>(forKey:defaultValue:) + 101 (DynamicConfig.swift:101)

Usage

lazy var myConfig: DynamicConfig = Statsig.getConfig(configName)
lazy var myVar: Int = myConfig.getValue(forKey: valueKey, defaultValue: 0) // -> the line that crashes.

Versions

• We've got this for several version now. The current version we're using is 1.48.1.

Hey @bodnar-dan, thanks for reporting this! We'll investigate this on our side. Overall, we're looking to refactor how our iOS SDK handles threads, which is what I assume to be the source of this crash.
