JS ERROR Error: Value is not a class.

And I don't think I use the symbol Value anywhere in my code.

[karo-dc]

@christocracy look, when I use this part 'app.ios.delegate = MyDelegate;', after that I get exception

[karo-dc]

What can I do to fix this?

[karo-dc]

now I have got this one
'NativeScript encountered a fatal error: TypeError: Attempted to assign to readonly property.

[ouss4m4]

@karo-dc you ever fixed that readonly property error ? i just updated my nativescript app to 5.3 and it hit me just like that, only on IOS , android is working fine
