Types
Here, you’ll find a comprehensive list of all types supported by the Typesync specification. Typesync’s powerful type system is designed to support a wide array of complex and useful types.
any
Represents any type.
unknown
Represents an unknown type.
nil
Represents the explicit absence of a value.
string
Represents a string value.
boolean
Represents a boolean value.
int
Represents a signed integer.
double
Represents a double-precision floating point number.
timestamp
Represents a datetime value.
literal
Represents a literal type.
Literal types are not supported in Swift. Typesync currently compiles literal types to the type of the literal value in Swift.
enum
Represents an enum value.
tuple
Represents a tuple value.
list
Represents a list of items.
map
Represents a mapping from arbitrary strings to values of any type.
object
Represents an object with known fields.
union
Represents a union of multiple types. Typesync supports two types of unions: simple union and discriminated union. Both are defined in the same way using variants, except a discriminated union definition has a discriminant key and requires every variant to be of object (or alias resolving to object) type.

alias
Represents an alias of another type.
