iOS Question (SOLVED) App Suddenly stopped working

[MrKim]

I was cleaning up some designer scripts in a b4x pages app I am working on and the app suddenly stopped working.

It Fails in Main Page Page_Created on the last line shown here (Drawer.LeftPanel.LoadLayout("MainPageMenu"):

Sub Class_Globals
.
.
.
    Private Drawer As B4XDrawer
.
.
.
End Sub

'This event will be called once, before the page becomes visible.
Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    'load the layout to Root

    Root.LoadLayout("Main")
    Dlg.Initialize (Root)
    'load MENU the layout to Root
    Drawer.Initialize(Me, "Drawer", Root, 200dip)
    Drawer.CenterPanel.LoadLayout("Main")
    Drawer.LeftPanel.LoadLayout("MainPageMenu")

Here is the error log:

I was NOT working on MainPageMenu that hasn't been changed in weeks.
I was working on Main, but nothing significant. And that line runs just fine.
The Android version of this runs just fine.

The error message comes from the Debug Version. I tried compiling a release app and it fails as well with no errors.
I cleaned the project.
I UnChecked and then Rechecked B4xDrawer(Version 1.52).
None of this helped.
Thanks for any clues.

Try to isolate a problem. Create a new project, add designer scripts and a code, which you posted,
Do you see troubles ? If yes, attach this project. If not, continue to add fragments.

I will try that tomorrow. I was hoping someone might recognize something from the error log.

Check the file itself in the Files folder. Its name should be lowercased.

Check the file itself in the Files folder. Its name should be lowercased.

Interesting, I removed the file from the list, restored it, and put it back in and it worked. However it now fails on the very next line

   HamburgerIcon = xui.LoadBitmapResize(File.DirAssets, "hamburger.png", 32dip, 32dip, True)

with the same error:

Error opening stream (/private/var/mobile/Containers/Data/Application/CB885317-1ECD-4B5E-9FE5-400053FF16F0/tmp/virtual_assets/hamburger.png): Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory" UserInfo={_kCFStreamErrorCodeKey=2, _kCFStreamErrorDomainKey=1}

I deleted it from files, cleaned the project, restored it, cleaned the project again, but this time no luck.
All files in Files dir are lower case.

Solved: I tried the obvious:
Deleted the app from the phone and reinstalled it.
