App is crashing after an IAP - only after podfiles were updated

I have an IAP setup in an app, along with a few Cocoapods:

- Firebase/AdMob (4.8.0):
- Firebase/Core
- Google-Mobile-Ads-SDK (= 7.27.0)
- Firebase/Core (4.8.0):
- FirebaseAnalytics (= 4.0.5)
- FirebaseCore (= 4.0.13)
- Firebase/Crash (4.8.0):
- Firebase/Core
- FirebaseCrash (= 2.0.2)
- FirebaseAnalytics (4.0.5):
- FirebaseCore (~> 4.0)
- FirebaseInstanceID (~> 2.0)
- GoogleToolboxForMac/NSData+zlib (~> 2.1)
- nanopb (~> 0.3)
- FirebaseCore (4.0.13):
- GoogleToolboxForMac/NSData+zlib (~> 2.1)
- FirebaseCrash (2.0.2):
- FirebaseAnalytics (~> 4.0)
- FirebaseInstanceID (~> 2.0)
- GoogleToolboxForMac/Logger (~> 2.1)
- GoogleToolboxForMac/NSData+zlib (~> 2.1)
- Protobuf (~> 3.1)


IAP and all of the above frameworks are working perfect! No problems at all.

Once I do a pod update, things start to go south.

After a pod update, here are the updated versions:

PODS:

- Firebase/AdMob (4.10.1):
- Firebase/Core
- Google-Mobile-Ads-SDK (= 7.29.0)
- Firebase/Core (4.10.1):
- FirebaseAnalytics (= 4.1.0)
- FirebaseCore (= 4.0.17)
- Firebase/Crash (4.10.1):
- Firebase/Core
- FirebaseCrash (= 2.0.2)
- FirebaseAnalytics (4.1.0):
- FirebaseCore (~> 4.0)
- FirebaseInstanceID (~> 2.0)
- GoogleToolboxForMac/NSData+zlib (~> 2.1)
- nanopb (~> 0.3)
- FirebaseCore (4.0.17):
- GoogleToolboxForMac/NSData+zlib (~> 2.1)
- FirebaseCrash (2.0.2):
- FirebaseAnalytics (~> 4.0)
- FirebaseInstanceID (~> 2.0)
- GoogleToolboxForMac/Logger (~> 2.1)
- GoogleToolboxForMac/NSData+zlib (~> 2.1)
- Protobuf (~> 3.1)


After this pod update - my IAP crashes on a successful purchase 100% of the time. Absolutely nothing changed in code. Just a pod update to the newest frameworks listed above.

I am getting the following crash once the IAP completes (and the "You're all set!" success alert pops up):

libc++abi.dylib: terminating with uncaught exception of type NSException

Here is what Firebase crash reporting is logging:

-[__NSCFBoolean timeIntervalSince1970]: unrecognized selector sent to instance 0x1b6f8a878


Some items to note:

What is causing this crash since I only updated pods?

Bounty update:

I have added a Bounty to this question because I am now experiencing it on other projects. I had an old project that i wanted to update the Pods (Firebase / Firebase Crash / Google Ads). Here are the exact steps I took:

Within Xcode, I run the project whose Podfile I updated... I go through purchasing an IAP and it crashes as soon as it's complete. Again, this does not happen before the pod file was updated! The IAP works fine until I run pod update.

With the newly offended broken project, I removed Podfile, Podfile.lock, and Pods directory. I dragged the same files and directory in from an older project. Works perfect without any crashing.

This problem is persisting ONLY after pod update. I'm lost..

To find where is this call for the TimeInterval being made I would add a public extension for Bool so you can add a breakpoint to it and modify accordingly.

Something like this:

public extension Bool {
public var timeIntervalSince1970:TimeInterval {
get {
// Add breakpoint here
return 0
}
}
}


I've temporarily fixed this issue by going back to the pod versions before I ran the update.

Here are the exact steps I took:

pod install

pod deintegrate

Podfile.lock

Workspace

I re-opened the Podfile, uncommented out the 3 pods, and then explicitly specified the dependency versions that I used before the pod update that was causing the crash. See below:

pod 'Firebase/Core', '4.8.0'

pod 'Google-Mobile-Ads-SDK', '7.27.0'

pod 'Firebase/Crash', '4.8.0'

The project works as intended now. The App completes the IAP with no exceptions.

Why is this occurring? I am led to believe it's NOT a code issue, because this issue only occurs when I update my pods.
