Mobile OS compatibility

The Mobile FIDO SDK supports multiple operating systems (OS) for both the iOS and Android platforms.

Each OS update is tested for compatibility with the latest version of the Mobile FIDO SDK.

Mobile operating system versions

The versioning of each mobile OS release is defined in accordance with the semantic versioning system, MAJOR.MINOR.PATCH where:

A MAJOR version is used when incompatible API changes are made.
A MINOR version is used when the functionality added is backward compatible with the previous version.
A PATCH version is used when backward compatible bug fixes are made.

Note

The exact version numbering of each OS is defined by the respective mobile OS providers and is subject to changes.

Typically, beta versions of the mobile OS are published ahead of the actual launch. This practice allows application developers to test the compatibility of their applications on the mobile OS, where:

The number of published beta versions and the dates they are published before the actual release are dependent on the mobile OS provider strategy.
The exact publication date of the actual release is not disclosed by mobile OS providers because it depends on the feedbacks received from the beta releases.
