Version 1.06 is not working on IOS 12.5.6

[YasserAntonio]

I have an iPhone 6 locked at the IOS version 12.5.6 and unfortunately my iOS auto updated Amperfy which is no longer working. Anyway to get a downgraded version and keep using Amperfy ?

I think is issue is a duplicate to this one: #65

[BLeeEZ]

Could you please install Amperfy via TestFlight: https://testflight.apple.com/join/HCZzB1fU
Via TestFlight it is possible to send crash reports, which help me to find the root cause.

[BLeeEZ]

I have seen in the meantime that only crash reports from iOS 13 and higher devices are available to developers.

Hello , sorry didn't saw the notification. I just join your test flight invite, installed Amperfy and opened it ( it crashed as expected) but I didn't got any bug report to send. Did you received something ?

I looked for some logs using Xcode and that's what I found, (I'm on iPhone 6):

It's seems like it's linked to a missing symbol " _kCACornerCurveCircular" used in your framwork. probably a breaking change in version. Tell me if it helps

[BLeeEZ]

Thank you very much for this log entry.
I think I now know where issue comes from.
The Carthage dependencies were not fixed to specific versions. They were declared as upwards compatible.

In the latest versions of LNPopupController were a lot of incompatibility issues with iOS 12.x (as you can see here: https://github.com/LeoNatan/LNPopupController/releases).
During the release process of Amperfy the versions of Carthage were updated and so the compatibility issues came into the App.
I fixed the Carthage dependencies to certain versions (22c0089). With that, this issue should not raise again in the future.

[YasserAntonio]

Must thank you first for your cool app ! Any idea when you will have time to make the next release with the fix ? I'm available if you need to test it before App Store release using testflight

[BLeeEZ]

I think next week or the week after will be a new version on TestFlight available. I will notify you here too when available.

[BLeeEZ]

The new beta is available. Does the app still crashes?

[YasserAntonio]

I just tested it and it’s working like a charm^^ Thanks !
