self = <LLDB error: no location, value may have been optimized out>: MiBanco.NumericPadButtonView

_amount = <LLDB error: parent failed to evaluate: no location, value may have been optimized out>: Binding<Decimal>

_maxDigitsReached = <LLDB error: parent failed to evaluate: no location, value may have been optimized out>: Binding<Bool>

button = <LLDB error: parent failed to evaluate: no location, value may have been optimized out>: MiBanco.NumericPadButton

After update xcode beta 26 custom numeric pad that use bindings variable get stuck my app when binigns variable change, and the console shows those messages

self = <LLDB error: no location, value may have been optimized out>: MiBanco.NumericPadButtonView

_amount = <LLDB error: parent failed to evaluate: no location, value may have been optimized out>: Binding<Decimal>

_maxDigitsReached = <LLDB error: parent failed to evaluate: no location, value may have been optimized out>: Binding<Bool>

button = <LLDB error: parent failed to evaluate: no location, value may have been optimized out>: MiBanco.NumericPadButton

As a first sanity check, could you verify that you're building a Debug version of your app, rather than the Release version, where optimizations are enabled? You should also take a look at your build settings to make sure that optimizations aren't enabled for your Debug build — SWIFT_OPTIMIZATION_LEVEL is set to -Onone, and SWIFT_COMPILATION_MODE is set to Incremental.
