Crash - unrecognized selector sent to instance

[Csaba8472]

First of all, thank you for the library!

With the latest Xamarin.iOS - xcode versions when I try to init RCPurchases:
RCPurchases.DebugLogsEnabled = true; RCPurchases.ConfigureWithAPIKey(API_KEY);

I get this exception:
[RCPurchases configureSubscriberAttributesManager]: unrecognized selector sent to instance

and RCPurchases.SharedPurchases is not initialised.

Full log:

[Purchases] - DEBUG: Initial App User ID - (null)

Tried 3.5.3.10 and 3.5.3.8 and both had this issue.

Also tried to update, but it seems from 3.6.0 the lib is modularized, and it has swift code too, so this method didn't work.

What did I do wrong?

@Csaba8472 Everything seems to be working just fine on our side (also when using newest xcode/sdks).

I will try to investigate the issue in detail today or tomorrow.

@Csaba8472 Tried to reproduce this issue. No success. What device and os are you deploying to?

[Csaba8472]

The easiest way is to create a new single view project, add Xamarin.RevenueCat.iOS and Xamarin.RevenueCat.iOS.Extensions and call it:

RCPurchases.DebugLogsEnabled = true; RCPurchases.ConfigureWithAPIKey(API_KEY);

(removed the API key before I created the screenshot)

Tried to run it on simulator with iOS 14.3. I don't think that simulator is the problem because revenuecat's native lib doesn't crash.

@Csaba8472 Thanks for that, will try to have a look into that one later today.

Current state:

1. I am able to reproduce the issue using a new project
2. Our own usage of the nugets is working just fine (xamarin forms solution)
3. The UsageChecker project ist working just fine

Currently, I have no clue on the cause of this issue. Further investigation is needed.

@Csaba8472 Do you know additional details, or hints on possible causes?

[thisisthekap]

@Csaba8472 I think I got it.

Please try to add <MtouchExtraArgs>-gcc_flags "-ObjC"</MtouchExtraArgs> to your project file.

If you prefer the UI dialog:

Thank you that solved the issue. In the meantime, I've wrapped RevenueCat's newest lib, do you plan to release an update to this lib which supports the newest RevenueCat lib?

@Csaba8472 Awsome!

So you successfully created Xamarin.iOS Bindings for the newest version of the RevenueCat SDK? If so: A PR would be very much appreciated!😎

[thisisthekap]

As #14 documents this fix in README.md, I think this issue can be closed. @Csaba8472 Do you agree?

[thisisthekap]

@Csaba8472 Did you manage to create the Xamarin.iOS Bindings for the newest version of the RevenueCat SDK?

[Csaba8472]

Yep, I agree, thank you for investigating it. Sort of, as the newest sdk is in swift I couldn't manually generate all the methods, instead I only wrapped the swift methods to objc which I needed and then I could bind those methods.

[thisisthekap]

@Csaba8472 As this imho is currently the only way to do propper swift bindings (https://github.com/xamarin/binding-tools-for-swift will most likely take some time to become stable), I think your new bindings are definitely worth a contribution.

Looking forward to your PR! 😊

@Csaba8472 Did you manage to create a working wrapper for the swift library?

[Csaba8472]

sorry forgot to write, still haven't had time to wrap all the methods. My current approach is creating a slim binding around RevenueCat.
