A version according to the semantic versioning specification.
- Xcode 10.2+
- Swift Package Manager
A package version is a three period-separated integer, for example
1. It must conform to the semantic versioning standard in order to ensure that your package behaves in a predictable manner once developers update their package dependency to a newer version. To achieve predictability, the semantic versioning specification proposes a set of rules and requirements that dictate how version numbers are assigned and incremented.

- The major version
The first digit of a version, or major version, signifies breaking changes to the API that require updates to existing clients. For example, the semantic versioning specification considers renaming an existing type, removing a method, or changing a method’s signature breaking changes. This also includes any backward-incompatible bug fixes or behavioral changes of the existing API.
- The minor version
Update the second digit of a version, or minor version, if you add functionality in a backward-compatible manner. For example, the semantic versioning specification considers adding a new method or type without changing any other API to be backward-compatible.
- The patch version
Increase the third digit of a version, or patch version, if you’re making a backward-compatible bug fix. This allows clients to benefit from bugfixes to your package without incurring any maintenance burden.
