Swiftmessages: [Crash] [SwiftMessages.MaskingView safeAreaInsets]: unrecognized selector sent to instance 0x111dcfb50'

[airspeed]

Yesterday I got this crashed log running SwiftMessages on an iPhone 8 iOS11.1 in a Swift4 app.
Could you help me debug the issue?
Thanks a lot!

Hi. I haven't seen this one before. SwiftMessages itself is referencing safeAreaInsets in a type-safe way, so I don't have any immediate theories to explain this error message:

'-[SwiftMessages.MaskingView safeAreaInsets]: unrecognized selector sent to instance

The greatest chance for success on this is if you can provide me with reproduction steps so I can look at it on my end. Can you attach a sample project that crashes consistently (maybe base on the SwiftMessages Demo project)? If not, you can try sending me copious code snippets from your app to give me an idea what it's doing.

Also, could you upgrade to SwiftMessages 4.1? From the stack trace, it looks like you're on an older version.

Hi, we were not able to reproduce this one ourselves, unfortunately.
By the first time this one appears, there was no new version of SwiftMessages available, will give now 4.1 a try and then report back, thanks a lot!

Haven't heard back. Closing

Similar crash in another project. Where for iOS 11 safeAreaInsets is unrecognised. But it happens 100% on Jalibroken devices

[LouisBorlee]

Got the same problem as @Igor-Palaguta , 100% crash on Jailbroken devices, would be very interested to know if someone has a lead on that

I stumbled upon this thread when looking for "safeAreaInsets crash jailbroken". I'm using safeAreaInsets.bottom in my code after checking for #available(iOS 11.0, *). In my case also all the crashes are from jailbroken devices. I believe you could fake your operating system version in jailbroken devices (https://yalujailbreak.net/lowerinstall/). My theory is that the crash occurs in jailbroken devices after trying to run unsupported APIs. For example the following will crash in a device which is pretending to be an iOS 11.

        if #available(iOS 11.0, *) {
            return safeAreaInsets.bottom
        } else {
            return 0
        }

I don't support jailbroken phones.
