iOS 15 Shortcuts misery

(1/2) > >>

Weaver:
Shortcuts in iOS 15 is nowhere near fit for release; it just falls over when I try to run some of my slightly more complex programs, ones that involve subroutine calling. (Proven by inserting good old fashioned printfs.) The subroutines in question run fine when called from a trivial test prog that simply passes the right input argus and then displays the return value, so there’s nothing going wrong in the subroutine itself; it’s in the call or return mechanisms when run within a more complex outer program that the fault lies. I’ve reported it to Apple using the new (and very telling) per-shortcut ‘report concern’ UI control.

I would like to downgrade to iOS 14 but I get the feeling that this is impossible, especially without a Mac or Wintel box to run the iTunes program (is that what it’s called?).

I believe Apple have stopped signing copies of iOS 14 - so if you've upgraded to 15, you can't downgrade

Weaver:
Some Shortcuts programs work ok, the simpler ones. I’m wondering if the ones that are failing are only those that call other routines, or possibly those that do comms. Some of my programs access a modem across the LAN, using local 192.168.x.y addresses, and some of those fail, but I can’t say for certain that they fail at the point where they initiate http operations.

I get an unhelpful, non-specific error message after a long delay - "there has been a problem", or something. I wonder if that error message means that a crash was detected in the Shortcuts engine? I get this in two of my most important programs - all to do with monitoring modems and the state of the DSL links. The failure seems, as best I can see, to be at a point where it calls a subroutine in order to consult a (fixed) ‘database’ and find out how many modems there are, what they’re called, where they are/how to address them. The ‘database’ is just hard-coded into a ‘network state info declaration’ subroutine, which is intended to be modified whenever things change.

Weaver:
Thank god. iPadOS 15.1 contains a bugfixed Shortcuts engine - works for the first time.

That's good news, I updated last night
