Hi,
How can we decide whether a variable needs to be a state variable or a regular variable?
and also in the examples at certain places the state variable are called with the ‘$’ sign and in some places its used without a ‘$’ sign. how do we decide when the $ sign is needed and when it is not.
I thought when we are calling a state variable we should always include the ‘$’ sign in front.
Hi
Just wondering what is better in a simple text display case - interpolation or conversion? An example being:
Text(“\(self.target)”)
vs
Text(String(self.target))
Thoughts?
