In 2016, [device tokens] may be growing up to 100 bytes.

This was mentioned at WWDC but is not yet mentioned in Apple's documentation.

Device tokens are currently 32 bytes (64 hexadecimal digits). Will they be either 64 or 200 digits? Will they be anywhere in between? It also said "may be growing", so maybe it won't even happen.

This isn't needed for the current version of iOS (9.2).

When it changes, it only impacts validations in Buford, but something to keep in mind if you are storing device tokens in a database.

The validation could be changed to not validate length or just have a minimum length.

[nathany]

they are now saying they are “variable length"

maybe this validation isn't that useful
