Hey @SandroMachado, that actually is a correct placement.
The Swift type name for a single permission is either ReadPermission/WritePermission or just Permission, so here we are referencing an array of Permission types, being Permissions 😁

Does it make sense? Or you think it's just too confusing?

[nlutsenko]

Maybe just removing the s in the end would make it clearer?

[SandroMachado]

Yup, removing the s makes more sense to me :)

[nlutsenko]

Great, please update the PR, sign the CLA and I'll gladly merge this in!
Congrats on being the first outside contributor!

[SandroMachado]

@nlutsenko Thanks. I think I already signed the CLA. Can you please confirm?

[nlutsenko]

Yup, ^ that tag above means that it's signed.
Update the PR with removal of s and we are all good to go.

[SandroMachado]

Updated. 👍
