iOS Question CrashDoctor Diagnosis: Application threw exception NSRangeException

[Filippo]

Hi,

i already have 2 users that sent the same crash report and i don't know where this can come from.
Has anyone seen something like this? If so, do you know where this can come from?

Application Specific Information:
*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 2 beyond bounds [0 .. 1]'

The error happens after a call to Sleep, you are getting the item with index 2 from a List with 2 items.

Thanks Erel!
Unfortunately it is not so easy to find the source and the crash report is unfortunately not so helpful.

I have found the error.
The error happens from iOS-16 .
This code worked without problems until iOS -15.

Private Sub FillCronoTimer(Timerlist As List, ListCronoTimerChanged As Boolean)
    Dim racetime1 As RaceProperty
    Dim pnl As Panel

    ClvIndex = ClvIndex + 1 'global int variable
    Dim MyIndex As Int = ClvIndex

    ShowProgressBar(True, 0)
   
    For i = 0 To Timerlist.Size -1
        Log("i=" & i & "/" & Timerlist.Size)
        racetime1 = Timerlist.get(i)          

        ...
        ...

        AddCronoTimer(Racetime,False)

        If Timerlist.Size > 10 Then
            ShowProgressBar(True, i / Timerlist.Size)
            Sleep(0)
        End If
       
        If MyIndex <> ClvIndex Then Return
    Next
   
    ShowProgressBar(False, 0)
End Sub

Private Sub ShowProgressBar(Visible As Boolean, Value As Double)
    pnlProgressBar.BringToFront
    pnlProgressBar.Visible = Visible
    lblProgress.Width = Value * (ProgressBar.Width - 2dip)
End Sub
