You can bind the return type by specializing the initializer:
```
let maximumAge = CoreStore.queryValue(
let maximumAge = dataStack.queryValue(
From<MyPersonEntity>(),
Select<Int>(.maximum("age"))
)
```
or by casting the type of the return value:
```
let maximumAge: Int = CoreStore.queryValue(
let maximumAge: Int = dataStack.queryValue(
From<MyPersonEntity>(),
Select(.maximum("age"))
)
