Helm: variables in values.yaml

Question

I have a need to use variables inside of values.yaml file:

app:
    version: 1.0

my_app1:
    tag: {{ .app.version }} <- version taken from appVersion. In my case tag == version

Any help will be really appreciated.

app:
    version: 1.0

my_app1:
    tag:  {{ .Values.app.version }}

{{ .Values.app | first | default .Values.app.version }}

You can also try this EDIT - 2

{{- range $key, $value := .Values.app }}
       {{ $key }}: {{ $value }}
{{- end }}

I've tried it before posted the question - the result is: ): error converting YAML to JSON: yaml: invalid map key: map[interface {}]interface {}{".Values.app.version":interface {}(nil)} – user2738882 Jun 20 '19 at 15:04
There were more spaces than 2 spaces. – Shudipta Sharma Jun 20 '19 at 15:38
